ABSTRACT:
A system for balancing power includes an internal combustion engine with at least two cylinders and a computer with a memory programmed to balance power output between the cylinders. Each of the cylinders has a fuel injector which injects fuel into the cylinder for a set period of time determined by a working pulse width signal received from the computer. The working pulse width signal is adjusted by a working balance factor which ranges from a first specified percentage to one-hundred percent before being transmitted to the fuel injector. The system operates in accordance with a set of instructions stored in the programmed memory which comprise: measuring peak firing pressure in each of the cylinders; generating an average peak firing pressure signal for each of the cylinders from the measurements of the peak firing pressure in each of the cylinders; generating a new balance factor for each of the cylinders in an iterative process from the working balance factors for each of the cylinders, a sensitivity constant, and the average peak firing pressure signal for each of the cylinders until at least one of the new balance factors is within a first preset amount of one hundred percent; and replacing the working balance factor for each of the cylinders with the new balance factor for each of the cylinders. The system and method may further comprise the step of triggering an alarm signal if any of the new balance factors is less than a specified percentage.
