Phaser control systems and methods for balancing mean effective pressure |
| 摘要 |
An engine control system includes a mean effective pressure (MEP) module, an imbalance module, and a phaser control module. The MEP module determines MEPs for combustion cycles of cylinders, respectively, of an engine. The imbalance module selectively determines whether first and second banks of the cylinders are imbalanced based on the MEPs. When the first and second banks of cylinders are imbalanced, the phaser control module selectively adjusts at least one of: a first phaser of an intake camshaft of the second bank of cylinders; and a second phaser of an exhaust camshaft of the second bank of cylinders. |

1. An engine control system comprising:
a mean effective pressure (MEP) module that determines MEPs for combustion cycles of cylinders, respectively, of an engine; an imbalance module that selectively determines whether first and second banks of the cylinders are imbalanced based on the MEPs; and a phaser control module that, when the first and second banks of cylinders are imbalanced, selectively adjusts at least one of:
a first phaser of an intake camshaft of the second bank of cylinders; anda second phaser of an exhaust camshaft of the second bank of cylinders. |
