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.
Linvention concerne un moteur à deux temps qui comporte des avantages des types de moteurs à deux temps et à quatre temps. Le carter de moteur est scellé et utilise une pompe à huile pour lubrifier le piston, une tige de raccordement et un carter de moteur. Lair de combustion ne sécoule pas à travers le carter de moteur. Au lieu de cela, le moteur utilise deux arbres à cames, un pour la soupape dadmission située sur la tête de cylindre et lautre pour la soupape déchappement située sur le côté du cylindre. Le moteur possède un compresseur, alimenté par la batterie du moteur pour compresser lair ambiant avant quil entre dans la chambre à combustion. En outre, le moteur possède une turbine alimentée par léchappement connectée à un alternateur, laquelle offre une alimentation supplémentaire pour la batterie du moteur. Le moteur est doté dun ou dune pluralité dinjecteurs de carburant. Le piston est du type à deux temps, ce qui réduit la friction entre le piston et le cylindre.
