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.
Claims7
An L-head two stroke engine comprising a first cylinder and a second cylinder, the two cylinders being connected to one another in perpendicular relation, a first piston mounted for reciprocable movement in the first cylinder and a second piston mounted for reciprocable movement in the second cylinder, a first crank and a second crank, a drive means drivably connecting the first and second cranks, means for supplying fuel to one of the cylinders, ignition means for igniting fuel in said one cylinder and means providing a communication between the two cylinders whereby in operation the compression ratio in said one cylinder is less than that in the other cylinder.
