A system in which electronic equipment on a vehicle sends signals back to a central control facility, locating the vehicle and providing other information about its operations or about its mechanical condition. AVI is also referred to as Automatic Vehicle Monitoring System and Automatic Vehicle Location System.Average Annual Daily Traffic (AADT)The total traffic for a year divided by 365.Average Daily Trafficis defined as the total traffic volume during a given period (from 1 to364 days) divided by the number of days in that period. Current ADT volumes can be determined by continuous traffic counts or periodic counts. Where only periodic traffic counts are taken, ADT volume can be established by applying correction factors such as for season or day of week. For roadways having traffic in two directions, the ADT includes traffic in both directions unless specified otherwise.Average Weekday Daily Traffic (AWDT)The total traffic for an average weekday. An average weekday is a representative weekday computed as the mathematical average of several typical weekdays selected at random throughout the year. A typical weekday has no anomaly such as heavy traffic due to a special public event or light traffic due to inclement weather. Average Saturday and Sunday data, including holiday service, are determined the same way.BBenefit/Cost (B/C) ratioB/C is used to compare the benefit versus the cost of proposedalternatives. For highway projects, benefits may include reduced fuel consumption, travel time, and air pollution; costs may include construction, right of way, and maintenance.BottleneckHighway sections that experience operational problems such as congestion. Bottlenecks may result from factors other than reduced roadway width. For example, the close spacing of exit and entrance ramps can cause weaving patterns that result in congestion. A less obvious example is a steep freeway grade that can slow trucks and cause a localized "bottleneck."CCapital Area Metropolitan Planning Organization (CAMPO) (formerly ATS)CAMPO is the Metropolitan Planning Organization (MPO) for the Austin area.CapacityCapacity refers to a rate of vehicular or person flow that can be expected to traverse a point or uniform section of a lane or roadway during a specific period, which is most often a peak 15-minute period, and which is not the maximum volume that can be accommodated during an hour, under prevailing roadway, traffic, and control conditions. Capacity and Level of Service (LOS) are analyzed separately and are not simply related to each other; both must be fully considered to evaluate the overall operation of a facility. Capacity analysis may be used in the computation of Volume-to-Capacity (V/C) ratios. In some cases, the V/C ratio is used to define LOS.Categorical ExclusionExamples of categorical exclusions are actions which, based on past experience with similar actions, do not involve significant environmental impacts. They are actions which do not do any of the following: induce significant impacts to planned growth or land use for the area; require the relocation of significant numbers of people; have a significant impact onany natural, cultural, recreational, historic or other resource; involve significant air, noise, or water quality impacts; have significant impacts on travel patterns; or otherwise, either individually or cumulatively, have any significant environmental impacts.Central Business District (CBD)The downtown retail trade and commercial area of a city or an area having high land values, traffic flow, and concentration of retail business offices, entertainment, lodging, and services.Changeable Message Sign (CMS)A CMS is used to advise drivers of traffic or roadway conditions ahead and, in some cases, recommend alternate routes. The CMS also reduces driver frustration by providing advance warning. A CMS is also referred to as a Variable Message Sign (VMS).Collector Distributor (CD)A CD freeway system separates local and through traffic by use of CD roadways and through roadways ("main lanes" or "core roadway"). The CDroadway is located between the main lanes and a frontage road or local street system. On the main lanes, traffic flow is improved since weaving is eliminated and access points are reduced; the CD roadway provides needed freeway access points. A CD roadway is different from a frontage road because access to adjacent properties is not permitted. A CD roadway can complement an existing frontage road system by inclusion of ramps connecting the CD roadway to the frontage road; the frontage road is then better able to handle traffic accessing adjacent properties. For traffic traveling between a freeway system and more distant points, "direct connect" ramps can be used to "directly connect" the CD roadway to major thoroughfares (leading to major traffic generation areas) and, thereby, bypass frontage roads or local streets adjacent to the freeway. This CD roadway and direct connect ramp arrangement eliminates merging and weaving movements that would otherwise occur between the freeway, frontage road, and local roads. During peak traffic, this arrangement can provide the added benefit of keeping open those sections of freeway lanes approaching exit ramps since greater storagelength for exiting traffic queues (lines of vehicles waiting their turn) is made; increased queue storage is made by the greater length of the direct connect ramps, the reduction of turbulence in the queue (no access to adjacent property), and the relocation of the queue away from, instead of parallel with the freeway. A CD system with direct connect ramps can promote intermodalism since it provides for easier movement of transit vehicles like buses. Buses can easily travel directly between the CD roadway and local streets without having to merge and weave on and off of frontage roads. The CD roadway's operating speed is generally lower than the main lanes since the CD roadway has more entrance and exit areas. It is worth noting that a freeway's optimal traffic carrying capacity occurs at around 45 mph. Because of this lower operating speed, the CD roadway may be designed with a lower design speed which allows for more flexible design. In general, a freeway system with high traffic volumes, in a city-type area, can have its overall traffic carrying capacity and flow operations improved by use of a CD system. CD systems are currently in operation in several cities across the nation.Commuter Rail (CR)Commuter Rail is urban passenger train service for short distance (local) travel between a central city and adjacent suburbs and long haul (regional) passenger service between cities. It does not include heavy rail service or light rail service (serving longer distances). Commuter rail service may be either locomotive-hauled or self-propelled, and is characterized by reduced fare multi-trip tickets, specific station-to-station fares, railroad employment practices, and usually only one or two stations in the central business district. Also known as "suburban rail." It may cross the geographical boundaries of a state. Congestion/Demand Management (CDM)See Transportation Demand Management and Congestion Management System .Congestion Management System (CMS)A systematic process which provides information on transportation system performance and alternative strategies to alleviate congestion and enhance the mobility of persons and goods. A CMS includes methods tomonitor and evaluate performance, identify alternative actions, access and implement cost-effective actions, and evaluate the effectiveness of implemented actions.Congestion Mitigation and Air Quality (CMAQ) improvement programA special provision of the ISTEA that directs funds towards projects in Clean Air Act Non-Attainment areas for ozone and carbon monoxide. Congestion PricingThe policy of charging drivers a fee that varies with the level of traffic on a congested roadway. Congestion pricing is designed to allocate roadway space in a more efficient manner. Congestion pricing is also known as relief tolling, variable pricing, and road pricing.Control of Access (COA)This is also referred to as access control. COA is the regulated limitation of access and is achieved by regulation of public access rights into (ingress) and out of (egress) properties abutting a roadway. There are two types: full control of access and partial control of access. Also, thereare driveway and approach control regulations. On a roadway with full COA, preference is given to the movement of through traffic by providing access connections only with selected public roads, by prohibiting crossings at the same grade, and by prohibiting direct private driveway connections. On a roadway with partial COA, preference is given to through traffic; however there may be access connections with selected public roads, crossings at the same grade, and private driveway connections. Full or partial access control is usually accomplished by legally obtaining right-of-access from the abutting property owners or by the use of frontage roads.Critical Movement Analysis (CMA)For signalized intersections, CMA focuses on lane groups or movements which control signal requirements. CMA focuses on the identification and provision of capacity for such flows called critical movements. CMA is also used in capacity analysis.DDesign Hour Volume (DHV)Typically, the DHV is the thirtieth highest hourly traffic volume for the design year, commonly twenty years from the time of construction. The DHV is given in units of vehicles per hour.Directional Design Hour Volume (DDHV)Typically, the DDHV is the thirtieth highest hourly traffic volume in one direction for the design year, commonly twenty years from the time of construction. DDHV is given in units of vehicles per hour.Draft Environmental Impact Statement (DEIS)An environmental document that is prepared when it is initially determined that the action/project may cause significant impacts to the environment, when environmental studies and early coordination indicate significant impacts, or when review of the environmental assessment indicates that the impacts anticipated to result from the project may be significant. The DEIS compares all reasonable alternatives to the proposedproject and summarizes the studies, reviews, consultations, and coordination required by legislation and Executive Orders to the extent appropriate at the draft stage in the environmental process. This document lists all entities from which comments are being requested.EEnvironmental Assessment (EA)A document that assesses an action that is not a categorical exclusion and does not clearly require the preparation of an environmental impact statement (EIS), or where the Federal Highway Administration believes an environmental assessment would assist in determining the need for an EIS.Environmental Impact Statement (EIS)An environmental document that is required when an action that will significantly affect the environment.Environmental Protection Agency (EPA)A Federal agency charged with protecting the natural resources onthe nation.ExpresswayAn expressway is a divided highway facility usually having two or more lanes for the exclusive use of traffic in each direction and partial control of access (as opposed to a freeway which has full control of access).FFeasibility StudyA study about a project's feasibility which is summarized in a document. The study addresses issues including the project's benefits, costs, effectiveness, alternatives considered, analysis of alternative selection, environmental effects, public opinions, and other factors. The feasibility study for major projects involving Federal funds was replaced under the Intermodal Surface Transportation Efficiency Act by the Major Investment Study.Federal Highway Administration (FHWA)The federal agency responsible for the administration of federal highway funds. FHWA does not have a direct role or responsibilities in the development of urban transportation plans or their development. However, their role is administration of federal funds and in the issuance of policy and procedure timetables for implementation of federal legislative directives is immense.Federal Transit Administration (FTA)The FTA was formerly as the Urban Mass Transportation Administration. It operates under the authority of the Federal Transit Act. The FTA was established as a component of the US Department of Transportation.Final Environmental Impact Statement (FEIS)An environmental document that is prepared following the Draft Environmental Impact Statement (DEIS), which includes the results of the public involvement process and agency input on the DEIS. This document summarizes the substantive comments on social, economic,environmental, and engineering issues made as a result of the public involvement process, and documents compliance with requirements of all applicable environmental laws, Executive Orders, and other related requirements.Flexible Operational Capabilityallows the direction lanes to change to accommodate uneven traffic flow. For example, during an evacuation, 7 northbound lanes can be created for evacuees and 1 southbound lane for emergency vehicles. FreewayA divided highway facility having two or more lanes for the exclusive use of traffic in each direction and full control of access. The freeway is the only type of highway intended to provide complete "uninterrupted" flow.Frontage roadAn arterial type roadway that parallels a major transportation facility such as a freeway. It serves to collect and distribute traffic along themajor facility without impeding flow along the freeway. Frontage roads are also referred to by the public as "access," "feeder," and "service" roads.GGradeThe slope (ratio of change in elevation to change in distance) of a roadway typically given in percent. For example, a 2% grade represents 2-feet of elevation change over a 100-foot distance.Grade SeparationA vertical separation between intersecting roads or railroad tracks. One facility travels over the other via an overpass or other structure.HHigh Occupancy Vehicle (HOV)Vehicles having more than one occupant. Examples include carpools, vanpools, buses, and mini-buses. Transportation systems may encourageHOV use by having designated HOV lanes.High Occupancy Vehicle (HOV) LaneHigh Occupancy Vehicle Lane. Exclusive road or traffic lane limited to buses, vanpools, carpools, emergency vehicles, and in some cases, single occupant motorcycles. HOV lanes typically have higher operating speeds and lower traffic volumes than adjacent general purpose lanes. HOV lanes have proven to be successful in major metropolitan areas across the US; however, their full effectiveness is usually not realized until about one to two years after implementation.High Speed RailA rail service having the characteristics of intercity rail service which operates primarily on a dedicated guideway or track not used, for the most part, by freight, including, but not limited to, trains on welded rail, magnetically levitated (MAGLEV) vehicles on a special guideway, or other advanced technology vehicles, designed to travel at speeds in excess of those possible on other types of railroads. High Speed Rail has exclusive right of way and serves densely traveled corridors at speeds of 124 milesper hour and greater.Highway Advisory Radio (HAR)A radio station which broadcasts highway conditions and traffic information.Hourly Volume (HV)The volume of traffic (given in units of vehicle per hour) that traverses across a segment of a roadway in one hour. The HV may be determined from traffic counts or may be a projected calculation. Refer to Design Hour Volume.IIncidentAn incident may be any of the following: traffic accident, stalled vehicle, load spillage, or other action that effects one or more lanes of traffic. An "accident" typically involves a collision of a moving vehicle with another vehicle, person, or object.Intelligent Transportation System (ITS)ITS replaces the term Intelligent Vehicle Highway System. ITS is a surveillance system designed to monitor traffic flows on major freeways and to inform motorists or problem areas. Some ITS technology includes changeable message signs, cameras, and video detectors. ITS applications include: the integration of traffic control and transportation management systems; traffic signals which adapt to traffic and change control each cycle; highway advisory radio systems; changeable message signs (CMS); vehicle detectors; closed-circuit television; Global Positioning Systems and route guidance (currently used in some trucks, buses, and rental cars). An ITS may enable drivers to operate their vehicles more safely and with greater knowledge about existing traffic conditions.Intelligent Vehicle Highway Systems (IVHS)See Intelligent Transportation System.Intermodal Surface Transportation Efficiency Act (ISTEA)A Transportation Bill passed by Congress in 1991 that provides six year authorizations for development of a National IntermodalTransportation System which consists of all forms of transportation in a unified, interconnected manner. It increased the percentage of federal match funding available for the majority of Texas transportation projects. ISTEA was designed to move goods and people more efficiently by developing an integrated transportation infrastructure system for the United States. ISTEA is this country's first serious effort to promote intermodalism, the idea that all systems and structures for moving people and goods must function as an integrated and cohesive transportation network which includes rail and mass transit as well as highways. Under ISTEA, the statewide planning process must incorporate some new goals: to reduce congestion and improve air quality; to consider national and international commerce; to consider energy conservation; to create an integrated system of several modes; and to concentrate on the most efficient way to move goods and people, not just people. The three major components of ISTEA are the National Highway System, the Surface Transportation Program, and the Congestion Mitigation and Air Quality Improvement Program.Intermodal TransportationTransportation of persons and goods that involves the interchange between transportation modes such as surface routes, airways, and waterways. Intermodal transportation for surface transportation of people and goods includes the interchange between modes such as automobiles, mass transit such as buses, railway includingcommuter rail and can include Park And Ride lots or other mode interchange facilities. Intermodal transportation enables people and goods to be consolidated into larger groups that can be transported at lower costs. In addition to reducing costs, it enables greater logistic flexibility than can also reduce congestion and travel time. IntermodalismA holistic view of transportation in which individual modes work together or within their own niches to provide the user with the best choices of service, and in which the consequences on all modes of policies for a single mode are considered. This view has been called balanced, integrated, or comprehensive transportation. Intermodalism includes theprovision of connections between different modes, such as highways to bus feeder services to rail transit.KK-FactorA factor which represents the proportion of Average Annual Daily Traffic (AADT) expected to occur in the design hour. The K-factor is also known as the design hour factor and is normally expressed in design problems as DHV = AADT x K, where the DHV is the total two-way Design Hour Volume, and K is estimated from the ratio of the 30th Hourly Volume to the AADT from a similar site.LLevel Of Service (LOS)A qualitative measure describing operational conditions within a traffic stream and motorists' perceptions of those conditions. For example, LOS A represents free flow, almost complete freedom to maneuver within the traffic stream. LOS F represents forced flow, more vehicles areattempting to use the freeway than can be served resulting in stop and go traffic.Light Rail Transit (LRT) or Light RailA railway with a "light volume" traffic capacity compared to "heavy rail." Light rail may use shared or exclusive rights of way, high or low platform loading, and multi-car trains or single cars traveling on fixed rails. LRT uses lightweight, streetcar type passenger vehicles operated on city streets that is not separated from other traffic for much of the way. LRT also known as light rail, streetcar, trolley car, and tramway.MMajor Investment Study (MIS)A study and resulting document which replaced Feasibility Studies under the Intermodal Surface Transportation Efficiency Act (ISTEA) for major improvement projects involving significant Federal funds. A MIS includes the study of factors that may justify a proposed project such as it's cost effectiveness and overall effectiveness and incorporation ofintermodal transportation. Measures Of Effectiveness are defined and calculated as part of the MIS. The MIS also requires consideration of other transportation modes as well as broader public and agency input. Measures Of Effectiveness (MOE)MOE include: average vehicle speed, vehicle stops, delays, vehicle-hours of travel, vehicle-miles of travel, fuel consumption and pollutant emissions. MOE provide insight into the effects on the traffic stream of the applied improvement strategy.Metropolitan Planning Organization (MPO)An association of local agencies established for mutual benefit and to help coordinate planning and development activities within a metropolitan region. Establishment of the MPO is required by law in urban areas of over 50,000 population if federal funds are to be used. The MPO consists of two groups. 1) The Policy board is comprised of officials representing the counties, cities, and state agency. 2) The technical advisory group consists of professional planners and engineers who are usually employees of the same agencies. The MPO is not a level ofgovernment. However, the MPO has "effective control" over transportation improvements within the area since a project must be a part of the MPO's adopted plan in order to receive federal funding.NNational Highway System (NHS)The NHS is one of the three major components of the 1991 Intermodal Surface Transportation Efficiency Act. A major new Federal-aid system was established in the NHS. It includes the Interstate System, other routes identified as having strategic defense characteristics, routes providing access to major ports, airports, public transportation and intermodal transportation facilities and, of particular significance to local governments, and many principal urban and rural arterials which provide regional service.National Transportation System (NTS)An intermodal system consisting of all forms of transportation in a unified, interconnected manner to reduce energy consumptions and airpollution while promoting economic development and supporting the Nation's preeminent position in international commerce. The NTS includes the National Highway System, public transportation and access to ports and airports.Non-attainment areasThese are geographical areas, defined by the Environmental Protection Agency, whose air quality does not meet Federal air quality standards designed to protect public health.North American Free Trade Agreement (NAFTA)A formal agreement, or treaty, between Canada, Mexico, and the United States of America to promote means for improved and increased free trade between the three countries. The affect of NAFTA on transportation was to increase the need to upgrade existing, and build new, transportation facilities between and within the countries.Notice Of Intent (NOI)A notice that is prepared to inform the public that an Environmental。

交通运输专业英语课件(Vehicle Fuel Economy)
Fuel consumption is substantially related to the type of vehicle, its power unit and drive line, its mechanical condition, the use to which it is put and how it is driven. 燃油消耗实际上与汽车类型、动力装置和传 动系统、机械状况、用途和驾驶方法有关。
Axles on bogies should be correctly aligned because tyres running at slip angles have a high rolling resistance and therefore are a source of increased fuel consumption. 因为轮胎以滑移角旋转时滚动阻力高,这样 会增加燃油的消耗,所以应该正确地调整转 向轴。
In the tests, at 40mph the fuel consumption was 10.5mpg, at 50mph this fell by 2.6mpg to 7.9mpg and at 60mpg a further reduction of 1.5mpg was experienced, making a 3.75mpg difference between 40mph and 60mph. 在试验中,以40英里/小时,燃油消耗为10.5 英里/加仑;以50英里/小时,该数字小了2.6 英里/加仑,下降为7.9英里/加仑;以60英里/ 小时,则进一步降低1.5英里/加仑的差值。从 40英里/小时到60英里/小时,产生了3.75英里 /加仑的差值。
The following activities should be avoided by careful route planning, scheduling and prior thought about the cost consequences. 通过认真的线路规划、日程安排和成本结果 的预先考虑,下列的行为应该避免。

The Transit Of Great Britain
The taxies and buses in London are bigger than Chinese. And they're colorfull. The bus in the picture is called "double-decker buses".British are conscious.If there are lots of people waiting the bus, they always line up.
• But it's also very crowded in subway station. So it's not very conveniet. • Buses are good choise. It is cheaper than the taxi. But in these times : schools over, work over and festivals , buses are always crowded . • China is crowded nearly every where. Because China has the great number of population.
Transpotation In China
• Traffic jam is ordinary in big citys such as Beijing , Shanghai . And it's not convenient . • The commonest mode of transit in Beijing is the subway.

In certain situations, exhaust system leaks can also lead to death.
Proper vehicle inspections can address exhaust system issues before these problems occur.
1.2 Exhaust system
Carbon monoxide from diesel emissions can be dangerous. Prolonged exposure to concentrations of CO can lead to headaches, shortness of breath, nausea, dizziness or light-headedness. These symptoms adversely affect a driver’s ability to safely control a commercial motor vehicle.
A cause of the fire was determined to be a hole in the fuel supply line, resulting in a fuel leak.

(3)Some lawbreakers make use of the leaks of the car rental contract to entice away the car. Thus, the car rental company has to pay their own money in exchange of the cars according to a deputy to the National People's Congress in 2010.
The health of the car rental industry partially determines whether the whole car industry can maximize its profits.
China’s car rental industry still faces many problems that need to be dealt with in order to let it develop healthily.

交通运输英语ppt【篇一:交通运输专业英语翻译】lesson1 to lesson3engine发动机发动机充当动力装置。
内燃机是最常见的:它通过在发动机汽缸里面燃烧一种液体燃料获得动力。
有2种形式的发动机:汽油机(也叫做火花点燃式发动机)和柴油机(也叫做压燃式发动机)两种发动机均被称为热机,有燃烧的燃油产生热,引起气缸内气体的压力升高,并输出动力使连接到传动系的轴旋转。
suspension悬架车桥和车轮通过悬架系统与底盘隔开。
悬架系统的基本作用是吸收由不规则路面引起的振动,从而有助于把车辆保持在一个受控的水平方向上,否则振动将传至车辆和车辆上的乘员。
steering转向系通过司机控制方向盘,转向系统为前轮转向提供手段。
转向系统为减少转动方向盘所需的力以及让车辆更易操纵提供了强力的帮助支持。
brakes制动系汽车上的制动系统有三个主要的功能。
它必须能让车辆在必要时减速;它必须能让车辆在尽可能短的一段距离内停下;它必须能让车辆保持怠速。
由于制动器迫使固定表面(制动衬片)接触旋转表面(鼓式或盘式)产生的摩擦力来完成刹车动作。
每个车轮具有一个鼓式或盘式制动总成,当驾驶员踩脚制动踏板时,靠液力产生制动principle of operation 工作原理这个发动机的四个行程见图2.2。
在吸气行程开始时,进气阀打开活塞在汽缸中从上止点运动到下止点。
通过活塞运动产生的局部真空,导致空气燃油混合物通过进气歧管进入汽缸。
化油器提供正确比例的空气燃油混合物。
当活塞运动到行程终点时进气阀关闭,因为两个阀都关闭着,所以使得汽缸上端密封。
在图2.2b中,活塞正向上运动,压缩汽缸和活塞之间的燃油混合物至一个很小的体积,--这就是压缩行程。
在到达上止点前,由火花塞电极产生的一个电火花,点燃了空气燃油混合物。
为了得到良好的性能,点火时刻必须精确控制。
随着空气燃油混合物燃烧,热空气膨胀气缸压力急剧上升,以致活塞被迫向汽缸下方运动。
使连杆对曲轴作用一个相当大的回转力。
这就是燃烧行程,也叫做做功行程,见图2.2c。
一旦混合物燃烧,它必须尽可能快的从汽缸内排出,在排气行程中,上升着的活塞把热空气和燃烧产物通过打开的排气阀和排气系统推出汽缸,排到空气中。
该行程依次按顺序连续循环,动力只在4个行程之一的燃烧行程传递给转轴。
由于与曲轴相连的一个很重的飞轮存在的动能,曲轴在别的行程中才能持续旋转。
注意到曲轴在一个四冲程循环中转过2圈,一个火花塞只在一个行程中出现在汽缸内。
在多缸的发动机中,为了发动机平稳的运转,每个汽缸的做功行程相间隔,以至于动力能持续的传递给曲轴。
carbureted fuel system化油系统在化油器中有六个不同的系统使它工作,这些系统在化油器中的排列方式决定了化油器的尺寸和形状。
(1)浮子系统(2)怠速和低速系统(3)主量筒系统(4)动力系统(5)加油系统(6)阻风门系统难以理解的是:用在四缸或六缸发动机上的小的单腔化油器和用在v8发动机上的打的四腔化油器具有相同的基本系统。
当然,四腔化油器具有更多的节流阀孔和硬件,这些是你在单腔化油器中找不到的。
然而,所有的化油器都是相似的,如果你了解了一种简单的单腔式化油器,你就能够运用这些知识来了解四腔化油器。
如果你研究各种系统的说明,你会发现化油器不如你想象的那么复杂。
事实上,考虑到他们完成的工作,它们很简单。
电子反馈化油器和传统化油器按照同样的工作原理进行工作,同时还有额外的优势,即通过电子控制的使用,减少尾气排放。
这个系统利用电子信号来精确控制化油器中的空燃比。
这些电子信号由氧传感器,节油阀位置传感器,冷却液温度传感器,气压计或歧管压力传感器产生。
那么反过来说,三元催化剂的使用允许发动机产生正确的废气混合物。
三元催化剂的设计是用来把这种污染物,碳氢化合物(hc),一氧化碳(co),和氮氧化合物转化成无害物质。
multi-port fuel injections多端口的燃油喷射在今天看来,这是一种最常见的燃料喷射系统,无论制造商是谁,它们都以同样的基本原理进行工作。
在这些系统中,等量的燃料被输送到每个汽缸中。
这些系统均运用传感器,把工作状况输入电脑里,这些由传感器产生的信息,通过电脑的处理,来决定合适的空燃比。
这个信号被发送到燃料喷射器中,喷油器打开,把燃料喷到它的气缸中。
喷油器保持打开的时间越长,燃料混合物将越浓。
大部分的燃料喷射系统依靠以下的一些信息来进行正确的操作:温度传感器——它包括空气温度和冷却液温度。
温度决定了混合物应该浓。
温度越低时稀,混合物越浓。
节油阀位置传感器或者转换器——计算机运用这些信息来决定节油阀气门的位置。
一些汽车在任何时刻都运用传感器来反映节油阀的精确位置。
其他的汽车运用转换器则仅仅来反映节油阀关闭和完全打开两个状态。
空气流量传感器——这种传感器同样也帮助计算机通过控制定量的空气进入发动机,来决定发动机的负荷。
空气流量传感器有很多种不同的形式,但最终都在做同样的工作。
歧管压力传感器——假如一辆汽车没装备空气流量传感器,那么它将用一个歧管压力传感器来决定发动机的负荷。
当发动机的负荷增加时,进气歧管的压力也随之增加。
发动机转速和位置传感器——发动机转速和位置传感器的信息可以由曲轴,凸轮轴或者两者一起共同确定。
除了帮助发动机决定负荷,这些传感器还能告诉计算机喷油器什么时候喷射。
这些系统在一个相对很高的压力下工作。
为了控制燃料的压力,一个燃料压力传感器被运用。
当发动机负荷增加时,燃料需要更大的压力。
这是由于混合物浓度变大,以及要克服汽缸中增大的空气压力。
没有用到的燃料经过回油管流回油箱。
喷油器可以一束,一排,或连续进行喷射。
在单孔喷油系统中所有喷油器同步喷油,这个时刻通常是在第一个汽缸压缩行程的上止点。
多孔喷油系统分为两排独立的喷油孔,当第一个汽缸处在排气行程上止点时,第一个喷油孔喷油。
对于连续喷射系统,每一个喷油器在它对应的汽缸处于压缩行程上止点时喷油。
这种方式往往是最高效的燃料喷射方式。
反馈燃料喷射系统运用氧传感器来精确监控空气燃料混合物。
通过运用氧传感器产生的信号,计算机能够改变喷油器的脉冲宽度。
喷油器喷油时间越长,燃料混合物越浓。
p25 离合器离合器是一种连接和脱离发动机的动力的装置,使汽车停止和启动。
压盘或“主动件”用螺栓连接在发动机的飞轮上,离合器片或“从动件”位于飞轮和压盘之间。
离合器压片用花键与从变速器伸出的轴(通常称为离合器轴或输入轴)连接,与飞轮结合。
当离合器和压盘通过摩擦缩在一起时,离合器轴与发动机曲轴一起旋转。
动力从发动机经过不同的齿轮比传递到变速器,从而获得最佳速度和动力来启动和保持汽车运行。
p28主减速器发动机曲轴与后轴成直角,因此必须在后轴上安装某种类型的齿轮装置,以便把动力传递到其轴线与传动轴成直角的每个后轮上。
有几种形式的齿轮装置,使得动力从一个轴传输到和它成直角的另一个轴,并且没有任何明显的功率损耗。
现在汽车主减速器被设计在4:1和5:1之间的减速比,当顶部或直接驱动齿轮与变速箱啮合时,以便后轮驱动以发动机转速的四分之一到五分之一,用于汽车实践的重要类型是:(1)斜齿轮;(2)蜗轮蜗杆。
就锥齿轮来说,它不过是由两个啮合在一起的带齿椎体所组成,这两个锥体的轴线相交在一点。
小锥齿轮用挠性联轴节(即万向节)与传动轴后端相连接,并与称为冠形齿轮的大锥齿轮相啮合,大锥齿轮与一个称为差速器的齿轮传动装置相啮合,以驱动两个后轮。
p33什么是变速器?变速器就是一种连接到发动机背部且能将动力从发动机传递到车轮的设备。
汽车发动机在一个确定的rpm(每分钟的旋转量)范围以它最佳的状态运行,当保持发动机在那个范围工作时,确保动力能够传递到车轮是变速器的工作。
变速器通过多种齿轮组合做到这一点。
在一档,发动机与车轮相比转速要快得多,然而在高的档位,即使汽车速度将超过70公里每小时,发动机也是闲置的。
除了多种前进挡,变速器同样有空挡切断发动机传给车轮的动力,然后转向,这就引起车轮转向相反的方向来使你倒退,最后有一个驻车档,在这一位置,挂钩装置被插入到输出轴的细长孔中来锁住车轮,阻碍它们转动,从而阻碍车辆的转动。
p57 4汽车的起动系统将电池的电能转换成驱动曲轴转动200转每分钟所需的机械能。
就在那时,发动机能利用燃烧空气燃料混合物产生的能量自己运转。
起动电机将会从曲轴上分离。
起动系统的基本部件是电池,起动电动机,起动机传动,点火线圈或者继电器,以及点火开关。
