  • Method of removing the fuel contained in the lubricating oil of an internal-combustion engine and engine using same
    Patent number: 8025041
    Abstract: The present invention relates to a method removing the fuel contained in the lubricating oil of an internal-combustion engine comprising an engine block with an air intake circuit for a fuel mixture, a burnt gas exhaust circuit, an oil sump and means for pumping the oil contained in the sump. According to the invention, the method consists in removing, after pumping the oil, the fuel diluted in the oil by heating intermittently the oil for a time ranging from 1/100 second to 10 second, in order to obtain vaporization of the fuel diluted in the oil.

  • Fuel mixture autoignition control method, notably for diesel type internal-combustion engines, and engine using same
    Patent number: 7937206
    Abstract: The present invention relates to a method for controlling autoignition of a fuel mixture, notably for a diesel type internal-combustion engine, according to which a fuel mixture is made in at least one combustion chamber (14) of the engine with a fuel and at least one fluid in order to obtain a homogeneous type combustion by autoignition. The method includes defining a desired combustion progress by autoignition of the fuel mixture, and adjusting the cetane number of the fuel used for the mixture to that of the fuel providing the desired combustion progress is obtained.
