| 摘要 |
The invention provides a fuel control method and system for an internal combustion engine. The method includes: calculating an initial amount of fuel based on an amount of intake air, calculating a first cylinder bank air/fuel ratio matching coefficient and a second cylinder bank air/fuel ratio matching coefficient based on an engine speed and a volumetric efficiency, and controlling the amounts of fuel in the second and first banks, using the calculated second bank air/fuel ratio matching coefficient and the first bank air/fuel ratio matching coefficient, respectively. The system includes a control unit and a fuel injection system for implementing the method.
