Abstract

Methods and systems for evaluating cylinder pressure profiles in cylinders of an engine are disclosed. In one example, fuel injection timing of engine cylinders is adjusted to improve engine combustion in response to output of one or more pressure sensors installed in engine cylinders. Combustion within a plurality of engine cylinders may be adjusted in response to pressure sensed in a single engine cylinder.
