摘要： A method for the direct injection of fuel into an internal combustion engine, wherein a high-pressure pump with a variable flow rate supplies the fuel to a common rail, which in turn supplies the fuel to a series of injectors; the flow rate of the high-pressure pump is controlled by choking each pump stroke by varying the closure time of an intake valve of said high-pressure pump; the mechanical actuation of the high-pressure pump is timed so that each injection interval is located at the beginning of a respective choking action; and each pump stroke is choked by at least an angular interval having a duration no shorter than that of the injection intervals irrespective of the quantity of fuel to be supplied to the common rail in such a way that the injection phase of each injector always takes place when the high-pressure pump is not pumping fuel to the common rail.

摘要： A method of updating the transmissibility function of a clutch during the final stage of a gear change, in which the clutch is closed to cause the angular speed of the drive shaft to equal the angular speed of the primary shaft of the gear change, the engine is set to supply a constant torque, the clutch is disposed in a predetermined position in order to transmit a constant torque greater than the torque supplied by the engine and the actual value of the torque transmitted by the clutch is calculated by subtracting the product of the moment of inertia of the engine and the angular acceleration of the drive shaft from the torque generated by the engine, the actual value of the torque transmitted by the clutch then being used to update the transmissibility function of the clutch.
