Intake Stroke:
Piston moves from TDC to BDC
creating vacuum in the cylinder
Intake valve opens allowing only
air to enter the cylinder and
exhaust valve remains closed
Power Stroke
Both valves stay closed
When the piston is at the end of
compression stroke(TDC) the injector
sprays a mist of diesel fuel into the
cylinder.
When hot air mixes with diesel fuel
an explosion takes place in the cylinder.
