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.
