10.It contains two basic electrical circuits:the primary circuit(low-vol
 
          
         tage circuit)and the secondary circuit(high-voltage circuit).The primary circuit consists of the battery,ignition switch,resistance wire,ignition coil primary winding,distributor contact point and connecting wiring.The secondary circuit consists of the ignition coil secondary winding,distributor cap,distributor rotor,spark plug and spark plug wire.
它包含两个基本电路:一次电路(低压电路)和二次电路(高压电路)。一次电路由蓄电池、点火开关、电阻线、点火线圈一次绕组、分电器出头和连接线组成。二次电路由点火线圈二次绕组、分电器盖、分电器转子、火花塞和火花塞线组组成。
11.The purpose of the ignition switch is to connect and disconnect the ignition system with the battery, so the engine can be started and stopped as desired.

点火开关的作用就是将点火系统与蓄电池进行连接或者断开,从而使发动机能够按照人的意愿起动或停止。
solenoid allows battery current to flow directly from the battery to the starter motor,which in turn cranks the engine.
电磁线圈允许蓄电池电流直接从蓄电池流至起动机,从而驱动发动机运转。
the cooltant temperature falls below this pri-set temperature,the thermostat blocks the coolant flow to the radiator,forcing the water instead through a bypass directly back to the engine.
如果冷却水温度低于设定温度,恒温器组织冷却水流入散热器,迫使冷却水从旁道回流到发动机。
engine lubrication system supplies oil to all the friction surfaces between the engine moving parts.
润滑系统为全部传动件的摩擦表面提供润滑油。
cylinder walls and pistonpin bearings are lubricated by oil fling dispersed by the rotating crankshaft.The excess oil is then scraped off by the lower ring in the piston.
