SYSTEMS AND METHODS FOR SUPPLYING GASEOUS FUEL TO AN ENGINE |
摘要 |
Systems and methods for supplying gaseous fuel to an internal combustion engine are presented. In one example, a gaseous fuel pump is selectively activated to extend a vehicle's operating range. The methods and systems may be useful for operating an engine that includes directly injected gaseous fuel. |

1. An engine operating method, comprising:
directly injecting a gaseous fuel to an engine in response to a pressure of a gaseous fuel stored in a fuel tank exceeding a threshold pressure; and activating a gaseous fuel pump only when the pressure of gaseous fuel stored in the fuel tank is less than or equal to the threshold level. |
