A fuel injection method and apparatus, suitable for use with an internal combustion engine operated on LPG, has a reservoir (1) for LPG with an outlet (9) connected via a pump (3) and a non-return valve (5) to a heating chamber (6), which is preferably heated by hot air or hot water, and then via a gas pressure regulator (12) to an injector (10). The apparatus operates such that LPG is pumped by the pump (3) through the non-return valve (5) to the heating chamber (6), where the LPG is heated to allow gaseous LPG to be transmitted to the injector (10) once a predetermined pressure set on the regulator (12) has been reached, whereupon the injector (10) injects the LPG into the crankcase, transfer ports, carburettor or cylinders of the internal combustion engine. The internal combustion engine may be a two-stroke engine, and lubricant may be injected into the engine along with the gaseous LPG using lubricant injection means that are arranged to adjust the amount of lubricant in accordance with engine speed, preferably by drawing the lubricant into the fuel flow by use of the venturi effect. |
