METHOD FOR MITIGATING CAVITATION |
| 摘要 |
Methods and systems are provided for mitigating loss of engine torque due to cavitation in a fuel pump. One example approach is adjusting engine operation or fuel pump operation based on ambient conditions and a measured engine torque being lower than a desired engine torque after a pre-determined duration. The ambient conditions may include one or more of ambient temperature being higher than a temperature threshold, barometric pressure lower than a threshold pressure, and fuel volatility higher than a threshold volatility. |

1. A method for an engine in a vehicle, comprising:
following an engine start,
adjusting engine operation or fuel pump operation responsive to detection of cavitation in a fuel pump, the detection of cavitation based on each of ambient conditions and a measured engine torque being lower than a desired engine torque after a first pre-determined duration. |
