| 发明名称 | Fuel system for an internal combustion engine | ||
| 摘要 | In a fuel system of an internal combustion engine, a low-pressure delivery unit for the fuel, at least indirectly delivers fuel to at least one low-pressure injection device. The fuel system further provides a high-pressure delivery unit, which has a drive region and a delivery region and at least indirectly delivers fuel to at least one high-pressure injection device. According to the invention, the fuel is first delivered by the low-pressure delivery unit to the drive region of the high-pressure delivery unit and from there onward to the low-pressure injection device and/or to the delivery region of the high-pressure delivery unit. | ||

| 主权项 | 1. A fuel system for an internal combustion engine, having a low-pressure delivery unit which delivers fuel to at least one low-pressure injection valve and having a high-pressure delivery unit which has a drive region and a delivery region and delivers the fuel to at least one high-pressure injection valve, wherein the fuel from the low-pressure delivery unit is delivered first via a fuel line into the drive region and the fuel is delivered both from the drive region directly to the at least one low-pressure injection valve and from the drive region to the delivery region. | ||
