METHOD OF TRANSITIONING BETWEEN OPERATING MODES IN AN INTERNAL COMBUSTION ENGINE |
摘要 |
A method of operating an internal combustion engine is provided. The method includes injecting a first fuel charge into at least one cylinder of the engine. The method further includes determining a value indicative of at least one of a cylinder pressure and a rate of change in cylinder pressure. The method further includes injecting a second fuel charge into the at least one cylinder, upon the occurrence of a predetermined contingency, which may be a determined cylinder pressure or rate in change thereof exceeding a predetermined threshold. An internal combustion engine is further provided, including an electronic controller having a control algorithm. The control algorithm includes software for determining a value indicative of at least one of a cylinder pressure and a rate of change in cylinder pressure of at least one cylinder of the engine. The control algorithm further includes logic for transitioning a fuel injector of the engine between modes, based upon the occurrence of a predetermined contingency, which may be the determined value. |
