Answer / krishna kanth

smaller vehicles like bikes, cars are started with the help
of motors. initialy, motors turn the crank shafttill
sufficient suction pressure is reached. when sufficient
suction pressure is reached, the engine starts to suck the
fuel in and then the cycle begins when the fuel is taken in
and ignited. similarly, for huge engines, instead of
motors, we use starting air. air at a pressure of 10-30 bar
is fed to the engine which is at rest. this air rotates the
engine till it attains sufficient suction pressure. once
the pressure is reached, the cycle starts and it starts
firing.

not moving. So when the vehical are in rest then the
pistones are moved.
