DIRECT INJECTION PUMP CONTROL |
| 摘要 |
Methods are provided for controlling a solenoid spill valve of a direct injection fuel pump, wherein the solenoid spill valve is energized and de-energized according to certain conditions. An example control strategy is provided for operating the direct injection fuel pump when fuel vapor is detected at an inlet of the direct injection fuel pump. To ensure pump effectiveness during the presence of fuel vapor, the solenoid spill valve may be maintained energized for a minimum angular duration past a top-dead-center position of a piston in the direct injection fuel pump. |
