two-stroke-cycle engine cycle
Two-stroke engine: combustion engine whose cycle (intake, compression, combustion and exhaust) requires one up-and-down movement of the piston.
Second stroke during which the piston is pushed back by the expansion of the burned gases, which are then expelled and replaced by the mixture coming from the crankcase.
End of the first stroke during which a spark ignites the air/fuel mixture.
Conduit through which the air/fuel mixture enters the crankcase.
Conduit through which the burned gases are expelled from the combustion chamber.
Sealed enclosure where the air/fuel mixture enters and the piston/connecting rod moves.
Conduit conducting the air/fuel mixture from the crankcase to the cylinder.
Beginning of the first stroke during which the piston moves up, drawing the air/fuel mixture into the crankcase and compressing the mixture in the cylinder.
Electric device whose two electrodes produce the spark necessary to ignite the air/fuel mixture in the cylinder.
