Patent ID: 7765979

Claim:
A system for controlling the operation of a diesel engine of a motor vehicle comprising means for supplying fuel to the cylinders thereof, the system comprising means for measuring the actual pressure in a combustion chamber of a reference cylinder and means for controlling the supply means as a function of the pressure measured and a predetermined desired fuel supply value for each cylinder, wherein the control means includes: slaving means for slaving the supply of fuel to the reference cylinder to its desired supply value as a function of the pressure measured; means for acquiring the drive shaft rotation speed generated by the displacement of the piston of the reference cylinder and the drive shaft rotation speed generated by the displacement of the piston of at least one other cylinder; and actuating means for actuating the supply of fuel to this at least one other cylinder as a function of a difference between (i) the drive shaft rotation speed generated by the displacement of the piston of this at least one other cylinder and (ii) the drive shaft rotation speed generated by the displacement of the piston of the reference cylinder.
