It is in (a) cycle stroke when the piston is at the top of its stroke and moving down. The mixture of air and fuel vapor is drawn through the inlet valve into the cylinder
It is in (a) cycle stroke when the inlet valve closes. The piston now rises compressing the air-gasoline mixture.
It is in (a) cycle stroke when the spark plug ignites the fuel which burns very rapidly. As pressure and temperature increases, burnt gases inside the cylinder expand pushing the piston down.
It is in (a) cycle stroke when the exhaust valve opens. Pressure inside the cylinder drops making the piston rise thus pushing the burnt gases out of the cylinder.
(a) is added to the engine which is a relatively high temperature.
Some of the energy from the input heat is used to do (a) .
The rest of the heat is removed and goes to the cold reservoir called (a)
