车辆工程外文翻译--日常汽车保养

外文翻译英文：Daily car maintenance. Auto maintenance aspects should be paid attention to:(1) prevent the mixture too thick due to the high temperature, gas to flow, but also because of quantity pore expansion, gas flow rate increase, and gasoline easy to evaporation, lead to the mixture too thick. Therefore, should be the small hole, speed up adjustment device and throttle rocker connection position, reduced float chamber oil surface height, to reduce the flow of.(2) prevent air resistance the burning hot summer, the gasoline engine fuel system due to temperature happen "gas resistance" phenomenon, fuel supply shortage or even interrupted the oil supply. To prevent "gas resistance", usable asbestos gasket will gasoline pumps and exhaust pipe is separated, or with wet cloth will cover the gasoline pump cooling.(3) the evaporation under high temperature, oil and water evaporation will increase, the flap raises to cover tightly, oil pipe to prevent oil leakage; Always check the water level of water tank, the crankcase oil oil face, height, brake zongbeng inside the brake fluid liquid surface height and within the battery electrolyte density and liquid surface height, etc. Illegal, want to add and adjust in time.(4) prevent overheating to prevent engine overheating, maintenance, attention shall be paid to fan belt can't with oil, in case the sliding, the degree appropriate belt. Driving timely rest, when resting, try to choose the shade, and open the hood ventilation cooling. When the tyre pressure because of the heat and increase when, should stop cooling, not use put gas and the method of threw cold water to reduce the tyre pressure and temperature.(5) the "combustion", "explosive" summer air temperature is higher, daily maximum temperature above 35 ℃in often, this makes the car itself also greatly improve the failure rate. When the high temperature heat slowly, auto water tank temperature often because do not fall high in and the influence of engine power, and may even cause mixed "combustion", "explosive", make the engine can't work normally. High temperature also makes some parts inflation deformation, light person can accelerate part wear, the person that weigh will blow out the parts. Summer road surface temperature at 70 ℃more often. Car tires for heated, the tyres increased pressure in, once the long distance running, easy blowout. When the car, a momentarybreaks down, it can also cause traffic accident.(6) the bad lubrication oil easily heated goes lean, oxidation resistance becomes poor, easy metamorphism, even cause the tile burning failure holding shaft. Therefore, should the crankcase and gear box with the oil changed into summer, often check the number of oil, lubricating oil, and in time to change.(7) the car paint the car paint him as insolate of skin, to bright and clean and bright beautiful, just cute. Although it seems to have no life, but it is also afraid of sun, long-term exposure willFaJiu, corrugate.The summer will often clean the car, in order to prevent the rain to car lacquer cause acid corrosion, also had better not on the street and wash your car, the repeated use of water sediment will scratch the car paint secretly. Next summer and the car that do more decontamination processing, summer bus is easy to splash on the viscosity substances, air temperature is exorbitant, will also be full of asphalt splash body. In that case, to do as soon as possible beauty treatment, using special detergents remove dirt, serious, want to undertake polishing processing. Some dirt if not handled in a timely manner, with all kinds of methods to remove not to drop, can only local polishing paint, paint again.The summer will pay more attention to the engine work environment, made timely cleaning work, if the engine external pollution too thick, it will affect the machine heat dissipation, give all sorts of machine fault buried hidden trouble. Summer should also be to paint on certain preventive protection, such as wax, glazing. Auto accessories part of the nursing in the summer also more important, such as the wheel hub, electroplating parts to timely derusting, clean, bumper, tires and other rubber and plastic parts to do add black glazing, anti-aging treatment.Common beauty protection- -wash the car wax, although some effect, but not for good. Because any waxes contain silicon ingredients, and ultraviolet ray will rust the car paint, leaving little black patches. And the car wax grinding particles, will be in the light of the car paint leave way way fine marks. Car wax itself up less than increase hardness, resistance ultraviolet function, will soon loss due to the temperature too high. Therefore, When the car parking shall be in the shade.The six main engine maintenance1. Use proper quality level of the lubricating oilThe engine should be for gasoline into the exhaust system according to additional devices and the using conditions choose SD-SF petrol engine oil level; Thediesel engine according to the mechanical load selection CB-CD level diesel engine oil, choose standard to not under production factory regulations shall prevail.2. Change regularly oil and filterAny quality level of the lubricating oil in use process of oil will change. To a certain mileage after, performance deterioration would bring a variety of problems to the engine. In order to avoid of failure, should combine conditions of use regular oil, and that the amount of oil moderate (generally in oil rod cap of good). The oil from the pores through the filter when the solid particles and viscous oil content stored up in filter. Such as filter jams, oil, not through the filter, will burst filter or turn on the relief valve, from bypass valve through, still the dirt back to lubrication part, make the engine wear, the internal worsening pollution.3. Keep the crankcase ventilationNow most of the gasoline engine are equipped with PCV valves (the crankcase forced ventilation device) prompted the engine take a breath, but channeling the pollutant in gas will "deposition in the valve, PCV around the valve plug. If possible PCV valves jams then pollution reverse flow gas air filter, pollution people filter core, make filtering ability, reduce inhaled mixture of dirty, caused the pollution, more crankcase to increase fuel consumption, engine wear more, even engine damage. Therefore, must be maintained regularly PCV, PCV valves clear around the pollutants.4. Regular cleaning the crankcaseThe engine running process, the combustion chamber not burning gas, high pressure water and sulfur acid, and of nitrogen oxide piston and cylinder wall after the clearance between into the crankcase, with parts wear produced metal powder mix together, form sludge. Quantity in oil suspended for a little time, large amount of precipitation from oil, blocked filter and the oil hole, cause the engine lubrication difficulties, caused by wear. In addition, the oil in the high temperature oxidation film and generates carbon bond on the piston, make the engine oil consumption, increase power decrease, serious when the rings card died and pull cylinder. Therefore, regular cleaning the crankcase and maintain engine internal clean.5. Regular cleaning fuel systemFuel in through the oil for the process of burning to the combustion chamber, inevitably will form the colloid and carbon, in oil,, carburetor, nozzles and deposited in the combustion chamber, interfering with the fuel flow, disrupt the normal air-fuelratio make fuel atomization bad, cause the engine out of shaking, blasting vibration, the idle instability, poor acceleration performance problem. Regular cleaning fuel oil system, control the generation of carbon, can always be the best to make the engine.6. Maintenance regularly water tankEngine water tank rust, scale is the most common problems. The grunge and scale can limit the cooling fluid in the cooling system, the flow, reduce the cooling effect, cause the engine overheat, even cause the engine damage. The cooling liquid oxygen also forms acidity material, corrosion water tank the metal components, causing the water tank damage and leakage. Regularly use the water tank cleaner water tank, remove the rust and scale, can not only ensure normal engine work, and extend the life of the whole water tank and the engine.中文：日常汽车保养汽车日常保养方面应该注意：（1）防混合气过浓由于气温高，汽油容易流动，还因量孔膨胀，使汽油流量增加，且汽油容易蒸发，导致混合气过浓。
