Abstract: An internal combustion engine having a compressed air assisted fuel injection system. The injection system has a compressed air accumulator with a first aperture into the cylinder of the engine and a second aperture into the crankcase of the engine. The two apertures are located at opposite ends of the accumulator and the accumulator has a tube shape. The accumulator blows off pressure every time one of the ports into the cylinder is closed. The tube shape of the accumulator forms a tuned reflection pipe for a compression wave from the cylinder to generate a reflected compression wave for assisting in delivering fuel and air into the cylinder. The two apertures are adapted to be opened and closed by the piston head of the engine.
