What Do You Mean By Four Stroke?

What is a 4-stroke diesel engine?As the slightly beyond the top dead center, the
name suggests, these engines work on fuel has acquired the
reciprocating temperature high enough for ignition.The
actions of pistons. One stroke means one fuel is supposed to burn so fast as to
linear motion of the explode. So there is
piston in one direction. When the piston no point in injecting it more than it
moves in the opposite can burn. If the fuel is
