  • Method of determining opening of an internal combustion engine intake valve
    Patent number: 8336374
    Abstract: A method of determining opening of an intake valve of an internal combustion engine, the method including the steps of: determining the time pattern of an intake pressure in an intake manifold of the internal combustion engine, the time pattern of the rotation speed of a drive shaft of the internal combustion engine, or the time pattern of a voltage at the terminals of a battery of the internal combustion engine; determining an intake-frequency component of the intake pressure, the rotation speed, or the voltage; and determining opening of the intake valve as a function of the intake-frequency component of the intake pressure, and also as a function of the intake-frequency component of the rotation speed or voltage.

  • METHOD OF CONTROLLING AN ELECTROMAGNETIC FUEL INJECTOR
    Publication number: 20110278369
    Abstract: A method of controlling an electromagnetic fuel injector including the steps of: determining a target quantity of fuel to inject; determining a hydraulic supply time as a function of the target quantity of fuel to inject and using a first injection law which provides a hydraulic supply time as a function of the target quantity of fuel; determining an estimated closing time as a function of the hydraulic supply time and using a second injection law which provides the estimated closing time as a function of the hydraulic supply time; determining an injection time as a function of the hydraulic supply time and of the estimated closing time; and piloting the injector using the injection time.
