SYSTEMS FOR FUEL DELIVERY |
| 摘要 |
Various systems are provided for delivering fuel to an engine. In one example, a system includes a controller and a fluid system configured to maintain a fluid at a pressure downstream of a check valve. The controller may be configured to determine if a leak is present in the fluid system based on a first pressure decay rate of the fluid system, and responsive to identifying that a leak is present in the fluid system, differentiate between an internal leak and an external leak based on a leak flow rate as fluid system pressure decreases. |

1. A system, comprising:
a fluid system configured to maintain a fluid at a pressure downstream of a check valve; and a controller configured to:
determine if a leak is present in the fluid system based on a first pressure decay rate of the fluid system; andresponsive to identifying that a leak is present in the fluid system, differentiate between an internal leak and an external leak based on a leak flow rate as fluid system pressure decreases. |
