1，every time the fuel system delivers air fuel mixture to a cylinder, the ignition system follows up by delivering an electric spark, this ignites the mixture which creates the high pressure that move the pistons and turn the car wheels, the action is repeated many times each second while the engine is running.,
2，the internal combustion engine is a device used to convert the chemical energy of the fuel into heat energy, and then to convert this heat energy into usable mechanical energy, this is achieved by combining the appropriate amounts of air and fuel, and burning the mixture in an enclosed cylinder at a controlled rate , a movable piston in the cylinder is forced down by the expanding gases of combustion
3，the efficiency of the internal combustion, reciprocating piston engine in converting the potential energy in fuel into mechanical energy is only about 33%,of the available heat energy in the fuel, about one-third is lost through the exhaust system and one-third is absorbed and dissipated by the cooling system, of the remaining one-thrid, about one-half is lost through available at the vehicles drive wheels
4，To start the engine, some method of cranking the engine is required to turn the crankshaft and cause piston movement, this is done by the starter motor when the ignition key is the start position, when sufficient air fuel mixture has entered the cylinders and is ignited, the power strikes create enough energy to continue crankshaft rotation, at the point ,ignition key is released to the run position and the starter is disengaged

Answer 1

1. 每次燃油系统输送燃油和空气的混合物到气缸里面，紧接着点火系统提供电火花。这样就可以点燃空气和燃油的混合物，从而产生强大的压力来使活塞运动以便推动车轮运转。只要在引擎点燃的情况下这个动作每秒钟会重复很多次。
