METHOD AND APPARATUS FOR DETERMINING OPTIMUM SKIP FIRE FIRING PROFILE |
| 摘要 |
In one aspect, a skip fire engine controller is described. The skip fire engine controller includes a skip fire module arranged to determine an operational firing fraction and associated cylinder load for delivering a desired engine output. The skip fire engine controller also includes a firing controller arranged to direct firings in a skip fire manner that delivers the selected operational firing fraction. Various methods, modules, lookup tables and arrangements related to the selection of a suitable operational firing fraction are also described. |

1. A skip fire engine controller comprising:
a skip fire profile module arranged to determine an operational firing fraction and associated cylinder load for delivering a desired engine output, wherein the skip fire profile module is arranged to select the operational firing fraction from a set of available firing fractions, wherein the set of available firing fractions varies as a function of cylinder load such that more firing fractions are available at lower cylinder loads than at higher cylinder loads; and a firing controller arranged to direct firings in a skip fire manner that delivers the selected operational firing fraction. |
