Abstract
A cranking fuel control method and apparatus for combustion engines. The method includes the steps of delaying the injection of fuel to the engine until one or more of the operating parameters of the engine, such as the engine rotational speed, the crankshaft rotation angle or the cylinder gas combustion pressure has reached a predetermined value. The fuel is then injected into the cylinder(s) at the required quantity for optimum starting of the engine. The method and apparatus can be used in fuel pumps with mechanical governors or with engines having electronic fuel controls.
