The invention relates to a fuel injection system more specifically to a compressed air assisted fuel injection system, for a two-stroke internal combustion engine, with small cylinder capacity. According to the invention, the injection system has a conduit with a first aperture in the cylinder, forming a fuel and compressed air injection port and a second aperture in the crankcase forming a compressed air entrance and a blow off port, wherein the piston opens and closes the two ports, having a reciprocating movement in the cylinder, the first and the second apertures are sufficiently spaced apart relative to each other, and the piston is sized and shaped such that the piston substantially simultaneously opens the compressed air entrance and blow off port and closes the fuel and compressed injection port, the blow off port remaining open as the piston moves to the internal dead centre position. |
