  • Burnt gas-scavenging indirect-injection internal-combustion supercharged engine and supercharged air supply method for such an engine
    Patent number: 7082764
    Abstract: The present invention relates to a supercharged internal-combustion, notably indirect-injection engine comprising at least one cylinder (10) with two types of supercharged air intake means (12, 14), one type for non-carbureted supercharged air intake (12) and another type for carbureted supercharged air intake (14), said intake means being supplied with supercharged air by supply means (38). According to the invention, supply means (38) comprise a specific supercharged air supply device (46, 50) for each type of intake means (12, 14).

  • Method for correcting ignition advance of an internal combustion
    Patent number: 6412472
    Abstract: The present invention is a method of ignition advance correction of an internal-combustion engine according to the composition variation of the natural gas contained in a tank and supplying the engine. A methane number relative to the natural gas filling the tank is determined and an ignition advance correction value is deduced from the number. According to the invention, a correlation is established between the methane number described above, an air-fuel ratio R for a stoichiometric combustion and the gas flow variation required to reach a reference working point of the engine after the composition variation of this gas.
