Abstract
Several embodiments of V type supercharged two cycle internal combustion engines, in all embodiments the supercharger supplies air to a scavenge manifold that extends at least partially around the cylinder bores and which serves the cylinder bores through a plurality of scavenge passages, each of which is disposed to direct the intake charge away from the exhaust ports. In some embodiments, the supercharger is positioned out of the valley of the V and in one embodiment, the supercharger is positioned in the valley of the V.
Claims13
A two cycle internal combustion engine having a pair of angularly related cylinder banks, defining a valley between said banks, each containing at least one cylinder bore, a pair of scavenge manifolds each at least partially encircling a cylinder bore of a respective bank, at least one scavenge passage extending from said scavenge manifold to the respective cylinder bore and opened and closed by a piston reciprocating therein, a crankcase containing a crankshaft rotatable about an axis, said cylinder banks extending on one side of a plane containing said crankshaft axis, and a supercharger for delivering a pressured charge to said scavenge manifolds positioned externally of said crankcase on the other side of said plane.
