ABSTRACT:
The electronic control module of the new generation of fuel injected internal combustion engines is adapted to compensate for variations in operating temperature or pressure readings among the cylinders, so that cylinders having a low temperature or pressure reading relative to the others will receive an increased flow of injected fuel, whereas cylinders running at a relatively high temperature and pressure compared to the other cylinders will receive a decreased fuel injection, so that the cooler cylinders run hotter and the hotter cylinders run cooler. The uniformity of power delivery among the cylinders, which is the object of the operating temperature and pressure adjustment, yields a more even delivery of power and a more efficient use of fuel.
