ABSTRACT:
Internal combustion engines having V-and L-configurations. There are first and second piston systems, each including: an engine block; a cylinder through the engine block; a piston within the cylinder, the piston with piston rings, including a cavity therein the underside; a stump member disposed within the cylinder and sized to be received by the cavity, and having a bore through the center to a direction of travel of the piston; a connecting rod, connected between the piston, and a crankshaft; a first and second combustion chambers defined between the piston, the cylinder, and the upper engine head, and between the piston, the cylinder, the stump member, and the cylinder floor respectively; an inlet port, an outlet port, and a spark plug/fuel injector port; each disposed through the engine block orthogonal to a direction of travel of the piston.
