(2) Two­Stroke cycle diesel engines. In two­cycle diesel engines, it
is necessary to force air into the cylinders and force exhaust gases at. One
way to do this is to use a supercharger or "blower". The General Motors (GM)
two­cycle diesel uses a positive displacement type blower to force air into the
cylinders (Figure 1­13).
Figure 1­13. Blower.
(a) Two­cycle diesel engines do not have intake valves. One
configuration used by the military has fair exhaust valves for each cylinder.
Air enters the cylinder through ports in the cylinder liner instead of through
intake valves (Figure 1­14). These ports are exposed each time the piston
moves down. Intake and exhaust will occur in the cylinder at the same time.
