SYSTEM AND METHOD OF CONTROLLING FUEL INJECTION PRESSURE IN AN ENGINE HAVING AN IN-CYLINDER PRESSURE SENSOR |
| 摘要 |
A method of operating an internal combustion engine is provided. An in-cylinder pressure within a cylinder of the engine is determined. A fuel injection pressure from a fuel injector disposed within the cylinder is determined. A ratio of the in-cylinder pressure within the cylinder and the fuel injection pressure is compared to a stored threshold value. The fuel injection pressure is adjusted based upon the comparison of the ratio of the in-cylinder pressure within the cylinder and the fuel injection pressure to the stored threshold value. |

1. A method of operating an internal combustion engine comprising:
determining an in-cylinder pressure within a cylinder of the engine; determining a fuel injection pressure from a fuel injector disposed within the cylinder; comparing a ratio of the in-cylinder pressure within the cylinder and the fuel injection pressure to a stored threshold value; and adjusting the fuel injection pressure based upon the comparison of the ratio of the in-cylinder pressure within the cylinder and the fuel injection pressure to the stored threshold value. |
