ABSTRACT:
An L-head two stroke engine comprises two pistons mounted for reciprocable movement in first and second cylinders respectively. The cranks of the two pistons are drivably connected such that the pistons are in phase. A fuel/air supply is provided for one cylinder where it is compressed and ignited causing both pistons to return to their respective bottom dead center position. The compression ratio in the one cylinder is less than in the other cylinder so as to aid retention of the air fuel mixture in the one cylinder prior to ignition.
