More Information
Summary:A pressure determining method is provided for a fuel distribution rail of an injection system of a motor vehicle comprising maximizing the fuel rail pressure to minimize particulate emissions of the engine. The method determines a setpoint pressure based on a calculation pressure being determined from a sum of a combustion chamber pressure and a square of a ratio of a fuel mass component and a pulse width, wherein the calculation pressure is output, at least temporarily, as the setpoint pressure.
