Abstract
An internal combustion engine, which has poppet type valve overlap and timing means and has the centerline of each and every cylinder being offset from the rotational axis of the crankshaft in the counter direction of rotation, provides efficient transformation of combustion energy to mechanical rotational power reducing exhaust loss, heat loss and detonation, and increasing volumetric efficiency. The engine also increases effective torque at certain rotational angle of an early stage of a power stroke. Thereby, the invented engine improves thermal efficiency.
