METHOD AND SYSTEM FOR CHARACTERIZING A PORT FUEL INJECTOR. |
摘要 |
Various systems and methods are described for calibrating a port injector of a common fuel, dual injector per cylinder engine which includes first and second fuel rails and first and second fuel pumps. In one example, after pressurizing both fuel rails and suspending operation of the two pumps simultaneously, a single cylinder is fueled by a port injector while the remaining cylinders are fueled via their respective direct injectors. Fuel rail pressure drops are measured in the rail coupled to the port injector and correlated to port injector performance. |
