ABSTRACT:
A device for controlling the ignition and the fuel injection of an internal combustion engine, including a pressure sensor, a position sensor associated with a target fixedly mounted in rotation with the crankshaft, a first computer of the programmed microcomputer type in which are stored values of the angle of advance and the injection time addressable as a function of the engine speed and pressure parameters, and a second computer which, from the output signal of the position sensor applies to the first computer a synchronization signal assuring the marking of each top dead center and/or each bottom dead center, the first computer receiving the output signal from the pressure sensor and computing, as a function of the parameters and under the control of the synchronization signal, the injection time and the angle of ignition advance, the value of the latter being applied by the first computer from the second computer which computes the conduction angle of the ignition coil and controls the conduction of the coil as a function of the computed angles of conduction and ignition advance.
