Method and device for determining the specific parameters of the injectors of a combustion engine, in particular of a pre-injection diesel engine.

摘要

The control circuit includes a processor which receives information from a sensor (2) operated by the accelerator pedal (3), a sensor detecting the tick-over speed (4) and an injection pressure sensor (5). Further sensors detect the speed of rotation (6) and the angular position of the cam shaft (7). Control of the injectors includes establishing the curve of difference between the time at which the piston passes through top dead centre and the time of ignition of the preceding cylinder. This is analysed whilst other factors remain constant, in order to determine the optimum value of this function. IMAGE
