USING CYLINDER FIRING HISTORY FOR COMBUSTION CONTROL IN A SKIP FIRE ENGINE
First Claim
Patent Images
1. An engine controller for an internal combustion engine operated in a skip fire manner, the engine controller comprising:
- a firing counter that stores a firing history of a working chamber in the engine; and
a combustion control module that is arranged to determine a combustion control parameter that helps manage combustion in the working chamber wherein the determination of the combustion control parameter is based at least in part on the firing history.

Abstract
Various methods and arrangements for determining a combustion control parameter for a working chamber in an engine are described. In one aspect, an engine controller includes a firing counter that stores a firing history for the working chamber. A combustion control module is used to determine a combustion control parameter, which is used to help manage combustion in the working chamber. The combustion control parameter is determined based at least in part on the firing history.
