DEFINITION

Classification: 123/70

Two-cycle recompression internal-combustion engines in which the working cylinder and the pump for supplying a combustible mixture thereto are located adjacent each other, axial lines

through the pump and motor cylinders being parallel and perpendicular to the axis of the main shaft of the engine and both lying in a plane passing through the axis of the main shaft. In engines in this subclass the supply-pump is inseparable from the engine and may draw both air and hydrocarbon into the cylinder thereof upon the suction-stroke, so that the pump operated upon the whole charge to be supplied to the working cylinder, or the supply-pump may draw in and discharge air only, in which case the combustible constituent of the charge is supplied to the air during its passage to the working cylinder.
