1. A supersonic nozzle for injecting gaseous fuel into the combustion chamber of a cylinder driven gaseous fuel engine, comprising: a valve body having an inlet for receiving gaseous fuel and an outlet for delivering such fuel directly into such combustion chamber; and, said outlet having a converging section coupled to a diverging section through a critical orifice for delivering gaseous fuel therethrough at a supersonic rate directly into such combustion chamber. 2. The supersonic nozzle for injecting gaseous fuel into the combustion chamber of a cylinder driven gaseous fuel engine of claim 1, wherein: the ratio of the cross-sectional area of said critical orifice to the cross-sectional area of said diverging section yields the supersonic rate of approximately Mach 2.5 to 3 (M＿2.5-3).
