12.发动机油泵必须提供一定压力和数量的油，以便于在任何情况下都能对整个系统进行润滑。
The engine oil pump must provide a continuous supply of oil at sufficient pressure and in sufficient quantity to provide adequate lubrication at all times to the entire engine.
13.内燃机是一个能将汽油中的化学能转化为热能并将其转化为可用的机械能的装置。The internal combustion engine is a device used to convert the chemical energy of the fuel into heat energy and then convert this heat energy into usable mechanical energy.
14.一些由冷却系统所吸收的热量被用来在寒冷天气为车厢供暖，并清除窗户上的水分和霜。
Some of the heat absorbed by the cooling system is used to heat the passenger compartments in cold weather and to keep windows clear of moisture and frost.
15.汽油机、柴油机统称热机，燃油燃烧产生热量使气体压力升高，提供动力使曲轴旋转。
Both gasoline and diesel are called heat engines. The burning fuel oil generates heat which causes the gas to increase its pressure and supply power to rotate the crankshaft.
16.空气冷却系统是以空气作为冷却介质用以冷却发动机各部件的。The air cooling system means that air is used as a cooling agent to cool the engine parts.
17.动力通过传动系从发动机传到车轮，从而车轮转动，汽车行驶。The power is carried from the engine through the power train to the car wheels so that the wheels turn and the car moves.
18.这一主要部件必须非常坚固刚硬，才足以抗得住任何的弯曲或扭曲。
This major unit must be strong and rigid enough to withstand any bending or distortion.
19.无论哪种情况，缸体本身都有许多部件铸在缸体之内或者附装在缸体之上。
In any case, the block itself has many components cast into it or assembled onto it.
20.如果让热量保留在发动机中，发动机会很快被烧损。
If the heat is allowed to remain in the engine, it would soon destroy it.
21.当润滑油供向发动机的各运动部件时，它吸收并带走发动机部件发出的热量。As the lubrication oil is fed to the various moving parts of the engine, it absorbs and carries the heat away from the engine parts.
22.凸轮轴必须和曲轴同步旋转，这样才能保证曲轴每旋转两周凸轮轴旋转一周。
The camshaft must be synchronized with the crankshaft so that it makes one revolution for every two revolutions of the crankshaft.
23.同时计算机会把故障记录在它的存储器中，技术人员可以在以后以故障码的形式读取这些故障信息，这些信息会有利于技术人员从中找到正确修理的方法。The computer will at the same time record the fault in its memory, so that technicians can at a later date retrieve that fault in the form of a code which will help them determine the proper repair.
24.活塞向上运动到气缸顶部，同时在排气门关闭之前排除所有的燃烧废气，为下一次新的四冲程循环做准备。
