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 momentary
breaks down, it can also cause traffic accident.
(6) the bad lubrication oil easily heated goes lean, oxidation resistance becomes poor, easy metamorp
hism, 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 wh
eel 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 maintenance
1. Use proper quality level of the lubricating oil
The engine should be for gasoline into the exhaust system according to additional devices and the using conditions choose SD-SF petrol engine oil level; The
diesel 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 filter
Any 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 ventilation
Now 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 crankcase
The 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 system
Fuel 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-fuel
ratio 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 tank
Engine 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。因此，应调小量孔，调整加速装置与节气门摇臂连接的位置，适当降低浮子室油面高度，以减少供油量。
（2）防止气阻炎热的夏季，汽油机燃料系统容易因温度升高而发生“气阻”现象，致使油路供油不足甚至中断供油。为防止“气阻”，可用石棉垫将汽油泵与排气管隔开，或用湿布将汽油泵包住降温。
（3）防蒸发高温下，油及水的蒸发都将增加，油箱盖要盖严，油管要防止渗油；经常检查水箱的水位，曲轴箱的机油油面、高度，制动总泵内的制动液液面高度及蓄电池内电解液密度和液面高度等。不合规定时，要及时添加和调整。
weigh翻译（4）防过热为防止发动机产生过热现象，保养时，应注意风扇皮带不能沾油，以防打滑，皮带紧度适当。行驶途中适时休息，休息时尽量选择阴凉处，并打开发动机罩通风散热。当轮胎气压因热而增加时，应停车降温，不得用放气及泼冷水的方法来降低轮胎气压和温度。
（5）防“自燃”、“自爆” 夏季气温较高，日最高气温常常在35℃以上，这使得汽车自身的故障率也大大提高。气温高时散热慢，汽车水箱的温度常常因为居高不降而影响发动机的功率，甚至可能引起混合“自燃”、“自爆”，使得发动机不能正常工作。高温也使得一些部件膨胀变形，轻者会加速部件磨损，重者会烧坏机件。夏季公路路面温度常常在70℃以上。汽车轮胎因为受热，胎内气压增高，一旦长距离行驶，容易爆胎。当汽车瞬间发生上述故障时，还有可能导致交通事故。
（6）防润滑不良润滑油易受热变稀，抗氧化性变差，易变质，甚至造成烧瓦抱轴等故障。因此，应将曲轴箱和齿轮箱里换上夏用润滑油，经常查润滑油数量、油质情况，并及时加以更换。
（7）车漆防曝晒车漆如同人身上的肌肤，要光洁亮丽，才惹人喜爱。虽然它似乎没有生命，但确实也怕晒，长期曝晒会发旧、起皱。
夏季要经常清洗爱车，以防止雨水对车漆造成酸性腐蚀，也最好不要在街边洗车，重复使用的水夹带泥沙会划伤车漆。其次夏季还要为爱车多做除污处理，夏天汽车上很容易溅上黏性物质，气温过高时，还会被沥青溅满车身。遇到这种情况，要尽快去做美容处理，用专用的清洁剂去除污物，情况严重的，要进行抛光处理。有些污物如不及时处理，用各种方法
