A two-stroke internal combustion engine having at least one cylinder with a combustion chamber defined between the cylinder head and a reciprocating piston, and a carburetor which delivers a rich fuel and air mixture to a compressor with a reciprocating piston driven by the engine to compress the mixture until the mixture is under sufficient pressure to open a differential pressure injection valve and thereby inject the mixture directly into the engine combustion chamber. The mixture is ignited by a spark plug to drive the engine piston through its power stroke and rotate its associated crankshaft which is connected to a crankshaft of the compressor to reciprocate its piston and thereby compress the fuel and air mixture and inject it into the cylinder in timed relation with the engine piston.

A flat commutator for an electric motor of a vehicle fuel pump. The commutator, is made with a one-piece carbon ring having a flat outer face, a one-piece conductor ring underlying the outer face of and embedded in the carbon ring, and a housing of a plastic insulating material molded on the rear face and the inner and outer edges of the carbon ring and adapted to mount the commutator on a motor armature. A plurality of circumferentially spaced apart grooves extend radially and axially completely through both the carbon ring and the conductor ring to provide a plurality of individual sintered carbon segments each with a separate conductor for electrically connecting the segments with armature coils.
