Abstract
A process for controlling the quantity of fuel injected into a diesel engine comprising at least one cylinder includes the steps of determining the pressure variation (.increment.P) within at least one cylinder around a specific time of the engine cycle, for two successive cycles (C.sub.1, C.sub.2) having different injection characteristics; deducing therefrom the difference between the quantity of fuel actually injected into the cylinder and a theoretical quantity of fuel; and adjusting the injection parameters so as to balance in real time the quantity of fuel actually injected with the quantity of fuel that is to be theoretically injected. The process is preferably implemented during stabilized running of the engine.
