ABSTRACT:
A 2-cycle engine having a transfer passage communicating the crank case with the combustion chamber. The transfer passage comprises a first passage and a second passage. The first passage has a long length and a small cross-sectional area for causing a fresh combustible mixture to flow at a high speed. The second passage has a short length and a large cross-sectional area for causing a fresh combustible mixture to flow at a low speed. An exhaust gas recirculation device is provided for recirculating the exhaust gas from the exhaust system into the intake system of the engine.
