| 摘要 |
The invention relates to a fuel injection system for a diesel engine cooled by a cooling water circuit comprising a storage tank, a distribution system, an injection harness and a draining circuit. The distribution system comprises a pump and a device for the selective heating of the fresh fuel flow before admission into the pump, and the injection harness injects part of the fuel into the engine. The draining circuit comprises a device for cooling the flow of non-injected fuel, and is used for the selective return of the flow toward the storage tank. The selective heating device comprises a recycle line and a direction setting element which can be used selectively to recycle the flow of non-injected fuel upstream of the pump.
