Compressed natural gas fuel injection system and method

The present invention provides a fuel injection for gaseous-fueled engines which comprises of a system and methos of injecting fuel direcly into the combustion chamber, wherein the gaseous fuel injector and fluid passage in perpendicular to the piston axis creating turbulence which is desirable to provide optimal mixing of gas fuel with air in the combustion chamber resulting in better engine performance and the gaseous fuel injector is disposed at an angle of between 0 and 30 degrees and is perpendicular to the piston axis with the injector nozzle positioned at no more than 5mm away from the isnition tip which results in increased ignitability and allowing gaseous fuel to be injected at any time resulting in optimized volumetric efficiency.
