）Compression（压缩）Crank-connecting Rod MechanismCrank-connecting rod mechanism(Fig.3-3) including the crankshaft，connecting-rod，piston and flywheel etc. Its role is to change reciprocating motion of piston and linkage into rotational motion of the crankshaft. In addition，the crankshaft is responsible for driving the camshaft by a camshaft timing gear，and operating the accessories through the belt sand pulley device driver. Lastly，the crankshaft carries the total torque-turning or twisting effort and delivers it to the flywheel. From the flywheel the torque then passes either to the friction clutch assembly or to the torque converter.（曲柄连杆机构(图3-3)包括曲轴、连杆、活塞、飞轮等。
它的作用是将活塞和连杆的往复运动转化为曲轴的旋转运动。
此外，曲轴负责驱动凸轮轴由一个凸轮轴正时齿轮，并通过带砂滑轮驱动装置操作附件。
最后，曲轴携带总扭矩旋转或扭转的努力，并提供它的飞轮。
从飞轮扭矩然后传递到摩擦离合器总成或扭矩转换器）Fuel supply systemThe fuel supply system has the job of supplying a combustible mixture of air and fuel to the engine.
