DIESEL ENGINE - TWO STROKE
Vertical flask type demonstration model, on metal base. This type of engine is
mostly used in motor boats. A two stroke diesel engine takes in air and discharges
exhaust through a system called crank-case scavenging. Scavenging begins with
piston at bottom dead centre. At this pointed, the intake part inside the cylinder are
uncovered and the exhaust valve is open. The air is forced into the cylinder, and as
the air is forced in, the burned gases form the previous operating cycle are forced
out. The two strockes involved are compression stroke and power stroke.
