PRINCIPLE OF OPERATION OF THE 2-CYCLE ENGINE
As the piston rises, it opens the inlet port and begins to draw a fresh mixture into the crankcase.
This is because the increasing crankcase volume lowers the crankcase air pressure below atmosphere.
At the same time, combustion chamber pressure begins to increase
. See figure 1
Piston reaches top of its stroke, spark plug ignites the mixture.
See figure 2
Rapid expansion of ignited mixture pushes the piston down. The inlet port closes.
See figure 3
Fuel supply: As piston descends in cylinder, it creates air pressure in the crankcase which escapes
through the fuel pump port in crankcase to the fuel pump causing the fuel pump membrane to expand.
As piston rises in cylinder, a vacuum is created inside the crankcase causing the fuel pump membrane
to contact. This process now creates a pumping action in the fuel pump, and to keep the gas flowing in
an upward direction to the carburetor, the pump has two check balls which act as one-way valves.
Exhaust begins. The burned gas is forced out due to high pressure in the combustion chamber.
See
figure 4
Transfer port opens. Descending piston forces fresh mixture through transfer port to combustion
chamber. The incoming fresh mixture helps to push exhaust mixture out.
See figure 5
Exhaust port closes. Compressions begins.
