This is a proposal for a two-stroke engine that incorporates advantages of both the two-stroke and four-stroke types of engines. The engine is lubricated exactly like a four- stroke engine; it has piston rings that lubricate the piston and the cylinder, i.e. the oil control ring, as well as all the customary lubricating parts such as the oil pan with the oil pump and the oil distribution system. The engine uses two camshafts, one for the intake valve and the other for the exhaust valve. The engine has a compressor, powered by the engine battery to compress ambient air before it enters into the combustion chamber. Additionally, the engine has an exhaust powered turbine connected to an alternator, which provides additional power for the engine battery. The engi ne is equipped with one or plurality of fuel-injection nozzles. The piston is of the two step type, which reduces friction between the piston and the cylinder. The operation of the engine is controll ed by a computer, the Engine Control Unit (ECU).
