IPC: F02B37/04
Filed: 2008-02-14
Abstract: The invention is a two-stroke engine that incorporates advantages of both the two-stroke and four-stroke types of engines. The crankcase is sealed and uses an oil pump to lubricate the piston, connecting rod and crankshaft. The combustion air does not flow through the crankcase.  Instead, the engine uses two camshafts, one for the intake valve located on the cylinder head and the other for the exhaust valve located on the side of the cylinder. 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 engine 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.
