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 / ravichandra kumbalavati
Piston moves in the same way. In small vehicals we are using gear system were at rest the driving wheel is not in contact with engine reciprocating system. Only when we made contact between them i.e with the help of Clutch then only the vehicals moves.
