Abstract:
A two cycle crankcase compression internal combustion engine comprised of an engine body that defines a cylinder bore, a piston reciprocating in said cylinder bore, said cylinder bore being provided with at least one scavenge port and at least one exhaust port that are opened and closed by the reciprocation of said piston, a fuel injector mounted in said engine body for injecting fuel directly into a combustion chamber formed by said piston and said engine body, means for supplying fuel under pressure to said fuel injector, and means for controlling the timing of fuel injection so that the beginning of fuel injection is initiated at a time between a time period beginning at a substantially maximum injection allowable angle and terminating at the time said exhaust port closes, and the substantially maximum injection allowable angle is determined by the length of time of crankshaft rotation angle between the beginning of fuel injection and the time when the infected fuel would reach said exhaust port.
