Two Stroke Cycle Diesel
a. General. The two stroke cycle diesel (figure 31 on the following page) is a
hybrid engine sharing operating principles of both a two stroke cycle gasoline
engine and a four stroke cycle diesel engine. The major features of the engine are
as follows:
(1) It completes an operating cycle every two piston strokes or every crankshaft
revolution. Like a two stroke cycle gasoline engine, it provides a power stroke
every time the piston moves downward.
(2) It is a compression ignition engine, making it a true diesel engine.
(3) It uses an exhaust valve on top of the combustion chamber as in a four stroke
cycle diesel engine. Intake ports are cut into the cylinder wall as in a two
stroke cycle gasoline engine.
