we have read that when the piston goes up and down then the
engine works i.e. the suction,compression etc etc.
then what happens in the case of big vehicles, which start
at stable condition, i.e. how does their piston moves when
they are at rest.
how suction,compression etc
Answer Posted / 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.

why we use kg/cm2 instead of kg/m2 as a unit of pressure. As we know kg is a MKS unit and cm is a CGS unit. So why we use combination of both(kg/cm2)while describing the pressure.
