Abstract
Injectors in an internal combustion engine are fed pulses via a gate which starts to transmit when the crank shaft of the engine is in a particular angular position and stops the transmission when the number of pulses applied to the injectors is equal to a number determined as a function of various operating parameters of the engine. The injectors remain open while pulses are being applied and close when the gate closes.
