초록 ▼

An internal combustion engine has a fuel system that has a fuel valve with a housing, wherein in the housing a fuel chamber is formed. A fuel pump pumps fuel from a fuel tank into the fuel chamber. A conveying pump provides forced conveyance of fuel into the fuel system. A feed line is connected to the fuel chamber of the fuel valve. The conveying pump is arranged in the feed line and supplies fuel to the fuel chamber. A relief line is connected to the fuel chamber of the fuel valve and a first valve is arranged in the relief line.

1. An internal combustion engine comprising: a fuel system comprising: a fuel valve with a housing, wherein in the housing a fuel chamber is formed;a fuel tank;a fuel pump comprising a pump chamber and pumping fuel from the fuel tank into the fuel chamber;a pressure regulator comprising a control chamber, wherein the pressure regulator is arranged in a flow path of the fuel in a flow direction from the pump chamber to the fuel chamber of the fuel valve;a conveying pump adapted to provide forced conveyance of fuel into the fuel system;a feed line connecting the control chamber of the pressure regulator with the fuel chamber of the fuel valve, wherein the conveying pump is arranged in the feed line so that the pressure regulator does not limit a fuel pressure generated by the conveying pump in the fuel chamber of the fuel valve when the conveying pump supplies fuel to the fuel chamber;a relief line connected to the fuel chamber of the fuel valve;a first valve arranged in the relief line. 2. The internal combustion engine according to claim 1, wherein the feed line is a bypass line bypassing the fuel pump and connecting the fuel tank to the fuel chamber. 3. The internal combustion engine according to claim 1, wherein the first valve is actuated as a function of an actuating pressure. 4. The internal combustion engine according to claim 3, wherein the actuating pressure actuating the first valve is a pressure in the fuel chamber. 5. The internal combustion engine according to claim 3, wherein the actuating pressure actuating the first valve is a pressure difference between the fuel chamber and the fuel tank. 6. The internal combustion engine according to claim 1, wherein the first valve is actuated as a function of an actuating temperature. 7. The internal combustion engine according to claim 1, wherein the first valve is actuated as a function of an actuating engine speed of the internal combustion engine. 8. The internal combustion engine according to claim 1, wherein the first valve is actuated by time control. 9. The internal combustion engine according to claim 1, wherein the first valve is actuated as a function of an actuating pressure and is a pressure retention valve opening in a relief direction of the relief line. 10. The internal combustion engine according to claim 9, wherein the first valve blocks in a direction opposite to the relief direction. 11. The internal combustion engine according to claim 1, wherein the first valve is actuated as a function of an actuating pressure and is an electrically actuated valve. 12. The internal combustion engine according to claim 11, further comprising an electronic control unit actuating the first valve. 13. The internal combustion engine according to claim 11, wherein the fuel system further comprises a second valve arranged in a bypass line bypassing the first valve. 14. The internal combustion engine according to claim 13, wherein the second valve is a pressure retention valve. 15. The internal combustion engine according to claim 1, wherein the conveying pump is manually operated. 16. The internal combustion engine according to claim 1, wherein the conveying pump is mechanically driven by a component of the internal combustion engine. 17. The internal combustion engine according to claim 1, wherein the conveying pump is electrically driven. 18. The internal combustion engine according to claim 1, wherein the conveying pump is pneumatically driven.
