METHOD FOR CORRECTING IGNITION ADVANCE OF AN INTERNAL COMBUSTION ENGINE |
摘要 |
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. |
