发动机术语解释

发动机术语解释

发动机术语解释发动机术语解释如下:1. 排量(Displacement):指发动机活塞在一个往返运动过程中,气缸容纳混合气的总体积。

一般用单位为升(L)来表示。

2. 马力(Horsepower):是一种用于衡量发动机输出功率的单位,表示发动机单位时间内所能发出的功率。

常用单位为马力(hp)。

3. 扭矩(Torque):表示发动机旋转力矩的物理量,是发动机输出力矩的强弱。

常用单位为牛·米(Nm)。

4. 缸径(Bore):指发动机活塞直径的大小。

一般以毫米(mm)或英寸(inch)为单位。

5. 行程(Stroke):指发动机活塞在气缸内上下运动的距离。

一般以毫米(mm)为单位。

6. 压缩比(Compression Ratio):指活塞在上止点与下止点之间的气缸容积比。

压缩比越高,燃烧效率和发动机功率通常会提高。

7. 点火提前角(Ignition Timing):指点火系统在活塞顶点附近开始点火的角度。

合理的点火提前角可以提高燃烧效率和功率输出。

8. 进气量(Air Intake):指每个循环中进入发动机气缸的空气量。

进气量的大小直接影响着发动机的输出功率。

9. 燃烧室(Combustion Chamber):是发动机中燃烧混合气的空间。

燃烧室的形状和尺寸对燃烧效率和动力性能产生重要影响。

10. 涡轮增压器(Turbocharger):是一种通过压缩进气增加发动机进气量和提高燃烧效率的装置。

通常由废气驱动。

以上是一些常见的发动机术语解释,供参考。

不同类型的发动机还有其他专业术语和工作原理,需要根据具体情况进行深入了解。

发动机专业术语

自然吸气:我们一般常见的发动机多数为自然吸气式发动机,自然吸气发动机是利用汽缸内产生的负压力,将外部空气吸入,跟人类吸取空气一样,这种吸气方式的发动机称为自然吸气发动机。

自然吸气发动机特点是:动力输出非常平顺,不会因为转速的变化而出现骤然的猛加速,而且使用寿命更长,维修更为简便。

涡轮增压:涡轮增压发动机是依靠涡轮增压器来加大发动机进气量的一种发动机,涡轮增压器(Tubro)实际上就是一个空气压缩机。

它是利用发动机排出的废气作为动力来推动涡轮室内的涡轮(位于排气道内),涡轮又带动同轴的叶轮位于进气道内,叶轮就压缩由空气滤清器管道送来的新鲜空气,再送入气缸。

当发动机转速加快,废气排出速度与涡轮转速也同步加快,空气压缩程度就得以加大,发动机的进气量就相应地得到增加,就可以增加发动机的输出功率了。

涡轮增压特点:一般增压后的发动机动力能比原发动机增加40%或更高;机械增压机械增压器采用皮带与发动机曲轴皮带盘连接,利用发动机转速来带动机械增压器内部叶片,以产生增压空气送入引擎进气歧管内,以此达到增压并使发动机输出动力变高的目的。

机械增压特点:机械增压优点是“全时介入”,使其在低转速下便可获得增压,加速感受相当线性化没有增压迟滞感;缺点就是依靠发动机曲轴带动的机械增压器,将损耗一定量发动机的动力,高转速损耗明显,燃油经济性降低,这点就不如涡轮增压系统好了。

目前,普通轿车多采用单机械增压,而一些超跑为了获取更大动力,还搭载装配两台增压器的双增压发动机,这两个增压器各为一半汽缸服务。

单点电喷以喷油嘴取代了化油器,进气总管中的节流阀体内设置一只喷射器,对各缸实施集中喷射,汽油被喷入进气气流中,形成可燃混合气,由进气岐观分配到各个气缸内。

单点电喷实现了电子控制,供油量精确度有所提高。

但是,化油器和单点喷射存在一个共性的缺陷,燃油雾化与进气混合的位置处于进气管距离气缸的最远端,油气混合后,要分配给各个气缸,无法实现精确的按比例并且均匀的油气混合,所以油耗高且动力低。

(完整word版)航空发动机术语

Acceleration lag --in the turbine engine,delay between the time instant power is requested and when power is available。

The time it takes the engine to accelerate and give the required power increase. Aerodynamic drag -—force which thrust must overcome to move an aircraft forward. Design can lesson aerodynamic drag through streamlining。

Drag increases with increased speed.Airbleed actuator -—device that operates the interstage bleed system,to improve compressor acceleration characteristics by unloading small amounts of compressed air.Air density-—total mass of air per given volume,the weight of a given volume of air. Air is denser at lower altitude, at lower temperature,and lower humidity。

Airfoil profile -—outline of an airfoil section.Airfoil section -—cross section of an airfoil parallel to a specific reference plane.Air-fuel ratio -—Ideal mixture of 15 parts of air to 1 part of fuel by weight;the mixture to be burned in the combustion chamber.Air inlet —-large,smooth aluminum or magnesium duct at mouth of engine which conducts air into the compressor with minimum turbulence and restriction。

发动机相关术语

发动机相关术语

发动机相关术语(1)上止点--活塞离曲轴旋转中心最远处,通常即活塞的最高位置。

(2)下止点--活塞离曲轴旋转中心最近处,通常即活塞的最低位置。

(3)活塞行程--上、下两止点间的距离。

(4)冲程--活塞由一个止点到另一个止点运动一次的过程。

(5)曲轴半径--曲轴与连杆大端连接的中心到曲轴旋转中心的距离。

(6)气缸工作容积--活塞从上止点到下止点所让出的空间的容积。

(7)发动机工作容积--发动机所有气缸工作容积之和,也称发动机的排量。

(8)燃烧室容积--活塞在上止点时,活塞顶上面的空间叫燃烧室,它的容积称燃烧室容积。

(9)气缸总容积--活塞在下止点时,活塞顶上面整个空间的容积,它等于气缸工作容积与燃烧室容积之和。

(10)压缩比--气缸总容积与燃烧室容积的比值。

发动机将热能转变为机械能的过程,是经过进气、压缩、作功和排气四个连续的过程来实现的,每进行一次这样的过程就叫一个工作循环。

凡是曲轴旋转两圈,活塞往复四个行程完成一个工作循环的,称为四冲程发动机。

曲轴旋转一圈,即活塞往复两个行程完成一个工作循环的,称为两冲程发动机。

1. 四冲程汽油机的工作原理:(1) 进气行程。

曲轴带动活塞从上止点向下止点运动,此时,进气门开启,排气门关闭。

活塞移动过程中,气缸内容积逐渐增大,形成真空度,于是可燃混合气通过进气门被吸入气缸,直至活塞到达下止点,进气门关闭时结束。

由于进气系统存在进气阻力,进气终了时气缸内气体的压力低于大气压力,约为0.075MPa~0.09MPa。

由于气缸壁、活塞等高温件及上一循环留下的高温残余废气的加热,气体温度升高到370K~440K。

(2) 压缩行程。

进气行程结束时,活塞在曲轴的带动下,从下止点向上止点运动,气缸内容积逐渐减小。

此时进、排气门均关闭,可燃混合气被压缩,至活塞到达上止点时压缩结束。

压缩过程中,气体压力和温度同时升高,并使混合气进一步均匀混合,压缩终了时,气缸内的压力约为0.6MPa~1.2MPa,温度约为600K~800K。

(word完整版)发动机相关术语

发动机相关术语所谓点火提前角是指压缩行程接近终了,火花塞开始向燃烧室跳出高压电火花时,活塞与上止点的距离,用曲轴转角表示.点火提前角是指从火花塞电极间跳火开始到活塞运动至上止点为止这段时间曲轴所转过的角度。

点火提前角会对发动机的排放、输出功率、燃油消耗量、汽车的驱动性能产生影响。

最佳点火提前角的一般定义是指发动机转速一定,混合气浓度及进气量保持不变的条件下,能使发动机输出扭矩达到最大,且比油耗最低的点火提前角,简称MBT(maximum brake torque timing)。

即在压缩过程中,火花塞跳火瞬间到活塞运动到上止点时的曲轴转角称为点火提前角.发动机扭矩其实就是发动机加速能力的具体指标,它的准确定义是:活塞在汽缸里的往复运动,往复一次做有一定的功,它的单位是牛米N.M。

在每个单位距离所做的功就是扭矩了。

就是指发动机所能输出的最大扭矩,是发动机性能的一个重要参数.一般来说,发动机只在某个转速时或某个转速区间内才有最大扭矩,这个区间就是在标出最大扭矩时给出的转速或转速区间。

最大扭矩一般出现在发动机的中、低转速的范围,随着转速的提高,扭矩反而会下降。

汽油机燃烧过程分为三个阶段:着火落后期,明显燃烧期,后燃期。

汽油机负荷特性,当汽油及保持某一转速不变,而逐渐改变节气门开度(同时调节测功器负荷,如改变水力测功机水量,以保持转速不变),每小时耗油量和耗油率随功率(或扭矩、平均有效压力)变化的关系。

测取前应将化油器。

点火提前角调整完好;测取时应按规定保持冷却水温,润滑油温度在最佳状态。

汽油机的速度特性,汽油机节气门(油门)开度固定不动,其有效功率、扭矩、耗油率、每小时耗油量等随转速变化的关系,测取前应将化油器。

点火提前角调整完好;测取时应按规定保持冷却水温,润滑油温度在最佳状态。

汽油机外特性是在节气门全开时测得,曲线上每一点表示它在此转速下的最大功率及扭矩,所以代表发动机的最高动力性能。

着火落后期是指从火花塞点火到火焰核心形成的阶段.发动机工况:是其工作情况的简称,它包括发动机的转速和负荷情况。

航空发动机术语简介

航空发动机术语简介

航空发动机术语简介编号术语解释备注1 喘振压气机的一类气动失稳现象,由于气流分离导致的增压能力的丧失,产生周期性的倒流、解除分离、正常流动、分离、再倒流的循环过程。

可通过中间级放气、双转子自动防喘、可调静子叶片和导向叶片、采用处理机匣等方法来防喘。

2 痒振进气道处于深度超临界状态下,通道中的附面层与正激波相互作用形成的分离区具有强烈的脉动性质,其压力表现为高频周期性变化,从而引起管道中激波的高频振荡,这种不稳定流动现象称为痒振。

4 质量附加涡扇发动机将从热机中获取的有效能分配给了更多的工作介质,参与产生推力工质增多,因此推力增大;“同参数”使涡扇发动机在相同热效率条件下降低了排气速度,减小了余速损失,具有更高的推进效率,因此提高了总效率,降低了耗油率;B越大,速度越低、推力越大。

5 余速损失绝对坐标系中气流以绝对速度(C9﹣C0)排出发动机所带走的能量称为“余速损失”。

yusun6 能量分配原则为减少气流掺混引起的损失,在混合室进口两股气流总压应大致相等,即Pt5II=Pt5,风扇压比的选择要遵循能量最佳分配原则。

7 同参数“同参数”的不同类型发动机具有相同的热力循环和理想循环功,总增压比和涡轮前温度相同,且具有相同的空气流量和燃油流量。

8 推力矢量能够控制排出气流的方向使推力方向变化的尾喷管称为推力矢量尾喷管。

目前通常是通过机械方法使喷管管道转向以控制推力方向的。

shiliang9 几何可调几何可调尾喷管指尾喷管喉道面积可调节,由此来改变气流在涡轮和尾喷管中膨胀比的分配,即改变压气机和涡轮的共同工作点,实现对整个发动机工作状态的控制,带加力的发动机必须几何可调。

10 共同工作各部件组合成整台发动机,部件间的相互作用和影响称为“共同工作”,共同工作条件:质量流量平衡;压气机与涡轮功率平衡;压气机与涡轮物理转速相等;压力平衡。

压气机特性图上满足共同工作方程的点组成共同工作线。

gongzuoxian11 调节规律被控制参数随飞行条件、油门位置、大气条件的变化规律称为控制规律(或调节规律)。
