Abstract

A control system for at least one fuel injector in an electronic fuel injection system for a heat engine in which the injector has a linear operating time range defined by a minimum opening time (MIT) and a minimum rest time (MIOT). The system includes a first processor for determining a theoretical injector opening time (TJ), and a second processor directing asynchronous opening of the injector with respect to the phase of the engine, subject to the criteria that the minimum opening and rest times are maintained, while the same linear proportion between the opening and closing time of the injector is also maintained, to ensure that the operating time does not exceed this linear range.
