Abstract
The fuel injection method uses a distributor-type fuel injector pump for an internal combustion engine which has a rotary distributor member formed with two outlet passages communicating with a pump chamber and arranged to distribute fuel intermittently to successive fuel delivery apertures leading to respective engine cylinders, so that in each revolution of the distributor the pump delivers to each cylinder a principal fuel injection at the end of the compression stroke, preceded by a pre-injection. Automatic timing control means advance the delivery stroke of the pump automatically in response to engine speed increase, and the angle between the outlets of the two outlet passages is such that as the engine speed varies the ratio of the fuel pre-injected to that of the principal injection into each cylinder varies according to a rule predetermined in relation to the type of engine (i.e. precombustion chamber or direct injection type).
