Abstract
Methods and systems for operating an engine responsive to filtered cylinder pressure data are disclosed. In one example, fuel injection timing may be advanced in response to filtered cylinder pressure data that is indicative of onset of combustion in a cylinder being delayed from an expected timing. The filtered cylinder pressure data may be generated via a digital filter.
