  • Method for estimating the filling of a cylinder in an internal combustion engine
    Patent number: 6728624
    Abstract: Method for estimating the filling of a cylinder in an internal combustion engine provided with cam stroke variation system. A theoretical induction efficiency which the cylinder would have if it operated with an optimal induction/exhaust timing value is estimated; said theoretical induction efficiency is derated by a correction factor depending on the induction/exhaust timing value actually used to estimate the induction efficiency, which is a standardised measurement of the filling of the cylinder.
    Type: Grant

    Date of Patent: April 27, 2004
    Assignee: Magneti Marelli Powertrain S.p.A.
    Inventors: Alessandro Palazzi, Jean Charles Minichetti
  • Method for correction of the spark advance for an internal combustion engine with a continuous phase transformer at the intake and/or exhaust
    Patent number: 6481416
    Abstract: Method for correction of the spark advance for an internal combustion engine with a continuous phase transformer at the intake and/or exhaust; for each cylinder, the method consists of calculating a theoretical value of the optimum spark advance according to the drive point, calculating a first correction value, which depends on the mass of burnt gas-trapped in the cylinder at the end of the intake phase, calculating a second correction value, which depends on the torque value generated, and calculating the actual value of the spark advance, by adding the two correction values to the theoretical value of the spark advance.
