METHOD FOR DETERMINING FUEL INJECTION ON-TIME IN A GASEOUS-FUELLED INTERNAL COMBUSTION ENGINE |
摘要 |
The present invention relates to a method and apparatus for determining the fuel injection on-time to accurately meter fuel injected directly into the combustion chamber of a gaseous fuelled internal combustion engine. The fuel injection on-time is determined by interpolating between values retrieved from two of a plurality of predetermined look-up tables, which each define fuel injection on-time as a function of gaseous fuel rail pressure and fuelling amount. Each table corresponds to a fixed value of a third parameter that correlates to in-cylinder pressure. |
