METHOD AND SYSTEM FOR LIMITING OUTPUT OF A BOOSTED ENGINE |
| 摘要 |
A method for operating a turbocharged engine is disclosed. In one example, during a first condition an engine operation is adjusted in response to a turbocharger expansion ratio exceeding a first limit and during a second condition an engine operation is adjusted in response to the turbocharger expansion ratio exceeding a second limit that differs from the first limit. Degradation of the engine may be reduced under some engine operating conditions by adjusting engine operation in response to the turbocharger expansion ratio. |

1. An engine operating method, comprising:
direct injecting fuel to an engine with a turbocharger; during a first condition, adjusting engine operation in response to a turbine expansion ratio exceeding a first turbine expansion ratio limit of the turbocharger; and during a second condition, adjusting engine operation in response to a turbine expansion ratio exceeding a second turbine expansion ratio limit of the turbocharger that differs from the first turbine expansion ratio limit. |
