Abstract
A method of controlling a fuel injector comprises measuring a pressure in a cylinder of an engine with a pressure sensor and determining at least one of a crank angle and a crank speed with a crank sensor. The method also comprises calculating a net indicated mean effective pressure of the cylinder from the measured value of the pressure sensor and the determined value of the crank sensor. Also, the method comprises adjusting a fueling parameter of a fuel injector for the cylinder in response to the difference between the calculated net indicated mean effective pressure and a reference mean effective pressure indicates a change in power of the engine. Alternatively, the method may adjust the fueling parameter based on a power feedback signal for the engine.
