  • SYSTEM AND METHOD OF CONTROLLING FUEL INJECTION PRESSURE IN AN ENGINE HAVING AN IN-CYLINDER PRESSURE SENSOR
    Publication number: 20150122223
    Abstract: 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.
