汽车发动机该怎么保养你知道吗?

来源:/ 日期:2019-03-06 发布人:admin
发动机是轿车的心脏,其效果是将燃料在汽缸中焚烧时放出的热能转变成机械能,向轿车提供动力。
The engine is the heart of a car. Its effect is to convert the heat energy emitted by the fuel burning in the cylinder into mechanical energy to provide power for the car.
发动机的核心是汽缸,还有与之相匹配的燃料、进气、排气、润滑、冷却等系统。轿车上常用的汽缸是四冲程汽缸。汽缸经过进气、紧缩、做功、排气四个冲程完结一个工作循环。小轿车上常用的是四缸、六缸、八缸发动机。
The core of the engine is the cylinder, as well as the matching fuel, intake, exhaust, lubrication, cooling and other systems. Four-stroke cylinders are commonly used in cars. Cylinder through intake, contraction, work, exhaust four strokes to complete a working cycle. Four-cylinder, six-cylinder and eight-cylinder engines are commonly used in cars.
汽(柴)油在进入汽缸前先与空气混合,再经过喷油咀和进气阀进入汽缸,做功行程完结后的废气经过排气阀排出发动机,再经过尾气净化装置进入大气。发动机输出的动力则经过曲轴连杆、变速箱等传动系统传递到车轮。
Steam (diesel) oil is mixed with air before entering the cylinder, and then enters the cylinder through the injection nozzle and the intake valve. After the completion of the work stroke, the exhaust gas is discharged from the engine through the exhaust valve, and then enters the atmosphere through the exhaust gas purification device. The output power of the engine is transmitted to the wheels through crankshaft connecting rods, gearbox and other transmission systems.
发动机动力下降由三个原因形成:
The engine power decline is caused by three reasons:
一是轿车设计制作水平的限制,
First, the level of car design and production is limited.
二是燃油品质差对机动车的发动机焚烧系统形成污染,
Secondly, poor fuel quality pollutes the engine burning system of motor vehicles.
三是忽略了污染后的发动机的彻底治愈。这些因素的效果,导致轿车发动机功率降低,焚烧雾化不完全、不充分,最终发生了尾气污染。
Third, it neglects the thorough cure of the polluted engine. The effect of these factors leads to the reduction of car engine power, incomplete and insufficient atomization of incineration, and eventually exhaust pollution.
发动机焚烧做功不可避免地要在污染发动机内部发生沉积物,形成汽油喷发变形,雾化不良,油耗添加,排放恶化,动力下降。
Engine incineration work inevitably results in sediment contamination inside the engine, resulting in gasoline eruption deion, poor atomization, fuel consumption, Emission Deterioration and power decline.
化油器积碳:使各油道、主量孔、怠速油量孔阻塞,使节气门的开度无法精确控制到位,影响化油器正常供油。
Carburetor Carbon Deposition: Blockage of oil channels, main measuring holes and idling oil measuring holes makes throttle opening unable to be accurately controlled and affects normal fuel supply of carburetor.
喷油嘴积碳:在喷油嘴顶部即针阀和金属孔表面的积碳,使喷油嘴通道阻塞,汽油喷发变形,汽油雾化差。
Carbon deposit in nozzle: Carbon deposit on the top of nozzle, i.e. needle valve and metal hole surface, blocked nozzle passage, deformed gasoline injection and poor gasoline atomization.
进油道、进气阀上沉积物发生节流效果,降低了最大功率,吸收喷发的汽油,扰乱了空燃比的控制,油耗添加,排放恶化;
The sediment on the intake port and intake valve has throttling effect, reduces the maximum power, absorbs the gasoline, disturbs the control of air-fuel ratio, adds fuel consumption and deteriorates emissions.
焚烧室的沉积物在形成比面容失调,表面焚烧续走,使焚烧室有效空间减少,紧缩比逐步添加,导致正常使用的车用汽油标号不匹配,对辛烷值要求进步,排放恶化;
The sediment in the incineration chamber is in the form of specific volume imbalance, surface incineration continues, which reduces the effective space of the incineration chamber and gradually adds the contraction ratio, resulting in the mismatch of normal vehicle gasoline labels, the improvement of octane number requirements and the deterioration of emissions.
焚烧室内的积碳在汽缸套空隙往复运行时,会发生研磨,加速发动机磨损,使润滑油患缸焚烧,驾驶功能变差,发动机功率下降,油耗添加,排放恶化。严重时还会发生暴震和积碳阻塞油路,形成发动机事端。
Carbon deposits in the incineration chamber will occur grinding when the cylinder liner gap is reciprocating, accelerating engine wear and tear, making the lubricant cylinder burn, driving function worse, engine power decline, fuel consumption addition and emission deterioration. Severe shocks and carbon deposits can also occur to block the oil pipeline, forming engine incidents.
其成果都是增大油耗,降低功率,焚烧不完全,排放添加,缩短发动机使用寿命,乃至损坏整个发动机。
Its results are to increase fuel consumption, reduce power, incomplete incineration, emission addition, shorten the life of the engine, and even damage the whole engine.
