  • Method for characterising the knock-resistance of fuels
    Patent number: 8468873
    Abstract: A method for characterizing the knock-resistance of a fuel using a test engine is disclosed, wherein the time versus cylinder pressure curve of the test engine during combustion of the fuel in the test engine is determined. This pressure signal is, in turn, compared with the corresponding pressure signal of at least one standard fuel of known knock-resistance.

  • Method for determining the ignitability of a fuel
    Patent number: 8397550
    Abstract: A method for determining the ignitability of a fuel, in particular a self-igniting fuel, based on the ignition delay of the fuel during the combustion in a test engine. According to the invention, the ignition delay is determined from the combustion curve and/or the heat curve.

  • METHOD FOR CHARACTERISING THE KNOCK-RESISTANCE OF FUELS
    Publication number: 20110036147
    Abstract: The invention relates to a method for characterising the knock-resistance of a fuel using a test engine, wherein the curve against time of the cylinder pressure of the test engine during combustion of the fuel in the test engine is determined and the determined pressure signals are compared with the corresponding pressure signals of a least one standard fuel of known knock-resistance.
