  • System for controlling the combustion noise a motor vehicle diesel engine
    Patent number: 6854441
    Abstract: This system for controlling the combustion noise of a motor vehicle diesel engine of the type including means for feeding each of its cylinders with fuel by multiple injections of fuel, which means are adapted to trigger fuel feed into each cylinder in the form of at least one pilot injection and a main injection of fuel, comprises: means for determining pressure gradients in the engine cylinder while in operation, at least during the pilot and main injection stages; and means for determining the quantity of fuel to be injected into the cylinder during pilot injection for a predetermined quantity of fuel injected during main injection so as to optimize a criterion based on the ratio between the pressure gradients corresponding to the pilot and main injection stages, thereby optimizing the operating noise of the engine.
