CONTROLLER FOR DIESEL ENGINE |
| 摘要 |
A controller for a diesel engine has a fuel injector which injects a fuel into a cylinder. The controller has a middle-combustion time computing portion which computes a middle-combustion time period that has elapsed from the fuel is injected until a half of the fuel has combusted, based on a detection value of a cylinder pressure sensor. Further, the controller has a fuel component computing portion which computes a ratio of a carbon quantity relative to a hydrogen quantity contained in the fuel based on the middle-combustion time period. |

1. A controller for a diesel engine having a fuel injector which injects a fuel into a cylinder, comprising:
a middle-combustion time computing portion which computes a middle-combustion time period that has elapsed from the fuel is injected until a half of the fuel has combusted, based on a detection value of a cylinder pressure sensor; and a fuel component computing portion which computes a ratio of a carbon quantity relative to a hydrogen quantity contained in the fuel based on the middle-combustion time period. |
