| 摘要 |
The invention relates to a device (16) for heating viscous fuel (6) for an internal combustion engine (4) of a vehicle, comprising at least one chamber (26) supplied with fuel from a fuel tank (8), which can be connected by fuel lines (64, 66) to a fuel pump (10) and an injection pump (18) of the internal combustion engine (4), an electric heater (28) for heating fuel (6) inside the chamber (26), a heat exchanger (30) which can be supplied with heated coolant from the internal combustion engine (4) in the heat exchanger contact with fuel (6) inside the chamber (26), and a fuel recirculation (70; 70, 76) branching off in the direction of flow of the fuel (6) behind the chamber (26). The invention also relates to a fuel facility and a method for heating viscous fuel. In order to improve the thermal efficiency of the device (16) particularly during heating the fuel (6) using electric power, it is proposed that the fuel recirculation (70; 70, 76) terminate in the chamber (26). |
