ABSTRACT:
This invention includes a method and apparatus for starting an internal combustion engine with a reduced starting time. That is, there is a reduced delay before the first combustion event occurs in the engine. Only a single engine position sensor is used. The method includes injecting fuel into a cylinder before true engine position is determined and applying an ignition pulse to the cylinder and firing the ignition coil after fuel has been injected into the cylinder. Advantageously, injecting fuel for the cylinder is done after determining the engine is turning and determining the engine has a rotational rate below a predetermined parameter.
