DETECTING MISFIRING IN A GASEOUS FUEL OPERATED INTERNAL COMBUSTION ENGINE |
| 摘要 |
A method of detecting an incomplete combustion, such as a misfire, in an internal combustion engine operating at least partly on a gaseous fuel, includes: receiving pressure data corresponding to a temporal development of a cylinder pressure during a combustion event within a combustion cycle; deriving from the pressure data a combustion energy value of the combustion; determining that the derived combustion energy value is beyond a predetermined combustion-cycle specific combustion threshold level; and associating the combustion event with an incomplete combustion in the combustion cycle. |

1. A method of detecting an incomplete combustion in a cylinder of an internal combustion engine operating at least partly on a gaseous fuel, the method comprising:
receiving pressure data corresponding to a temporal development of a cylinder pressure during a combustion event within a combustion cycle; deriving from the pressure data a combustion energy value of the combustion; determining that the derived combustion energy value is beyond a predetermined combustion-cycle specific combustion threshold level; and associating the combustion event with an incomplete combustion in the combustion cycle. |
