Effect It is possible to return excess oil to the tank, which can discharge the pressure of gasoline and reduce fuel consumption, not only to ensure that the inlet of the injection pump will not produce vaporization and cavitation due to too low oil pressure, but also to avoid cavitation to ensure the continuity of the oil supply of the high-pressure oil pump and make the engine work stable.
Production method

Production method
Technical field:
The utility model relates to the field of engines, in particular to an engine fuel injection pump return oil pipe.
Background technology:
In the existing technology, the fuel line of the engine is usually designed and arranged according to the aesthetic direction of the oil pipe. The oil return pipe of the injector is first connected to the oil return hole of the engine fuel injection pump, and then the oil return of the fuel injection pump flows back to the fuel tank through a pipeline, because the oil return pipe of the injector is relatively long, due to its own and other pipelines and components connected to it are not tightly sealed, resulting in air mixed in the oil circuit of the injector return, and the inlet is directly set in the oil return hole of the fuel injection pump. It is easy to cause the air mixed in the oil circuit of the injector to be compressed into the injection pump, which affects the pump oil performance of the injection pump, and then the engine is difficult to start, and also causes the rail pressure of the pipeline to be unstable, affecting the operation performance of the engine.

The utility model solves the technical problem of providing an engine fuel injection pump oil return pipe which prevents the air in the oil return pipe of the fuel injector from entering the engine fuel injection pump and affecting the oil pumping performance of the fuel injection pump. To achieve the above purpose, the utility model provides an engine fuel injection pump return oil pipe, which comprises an oil pipe drawn upward from an oil injection pump return hole and a fuel tank nozzle connected with the oil pipe. The return oil pipe of the fuel injector is connected by the connection point of the oil pipe and the oil tank nozzle. Further, the tubing is drawn vertically upward from the oil return hole of the injection pump. Further, the upper end of the oil pipe is arranged with a tee joint, and the oil tank nozzle and the return oil pipe of the fuel injector are connected with the oil pipe through the tee joint. According to the technical scheme of the utility model, since an oil pipe from the oil return hole of the fuel injection pump is added to the oil return pipe of the engine fuel injection pump, part of the oil return pipe is always retained in the oil return pipe of the fuel injection pump to seal the oil pipe during the oil return process of the fuel injection pump, so that the oil return pipe of the fuel injector cannot be directly connected to the oil return hole of the fuel injection pump, and the air in the oil return pipe of the fuel injector is prevented from entering the engine fuel injection pump. The pump performance of the fuel injection pump is affected, and the starting of the engine is affected.

Figure 1 is a structural diagram of an engine fuel injection pump return pipe according to the utility model.
Concrete implementation mode

The following is a specific implementation method of the utility model in combination with the attached drawings
However, it should be understood that the protection scope of the utility model is not subject to the specific embodiments
The limits of... As shown in Figure 1, the oil return pipe of the engine fuel injection pump comprises a section of oil pipe 1 drawn upward from the oil return hole of the oil injection pump and a fuel tank nozzle 2 connected with the oil pipe 1. The lower end of the oil pipe 1 is provided with a connection bolt 11 for connecting the oil pipe 1 to the oil return hole of the oil injection pump. The upper end of the oil pipe 1 is provided with a tee joint 12, and the left end of the tee joint 12 is connected with the oil tank nozzle 2. Right end of the return line connected to the injector 3. Tubing 1 can be drawn vertically up from the oil return hole of the fuel injection pump, thereby reducing the cantilever of the upper tee joint 12 and increasing the reliability of the oil connection. [0011] The oil return of the engine fuel injection pump flows through the oil line 1 of the fuel injection pump return line to the tee joint 12 to meet the oil return line 3 of the oil device, and then flows back to the oil tank through the tank nozzle 2 (not shown in the figure). The oil return of the engine injection pump can only be returned to the tank by rising to the part of the tee joint 12, and some oil return is still retained in the upward oil pipe 1. Because this part of the oil return is closed to the oil pipe 1, the air in the oil return pipe 3 of the injector cannot enter the engine injection pump through the oil pipe 1. In addition, the direction of the oil pipe 1 is upward from the oil return hole of the injection pump. The air in the return pipe 3 of the injector is less dense than the fuel, so that the air is collected upward and cannot enter the engine injection pump through the oil pipe 1, which prevents the air in the return pipe of the injector from entering the engine injection pump, and affects the pump performance of the injection pump, and then affects the start of the engine. The above disclosed is only a specific embodiment of the utility model, however, the utility model is not limited to this, and any changes that can be contemplated by technical personnel in the field shall fall within the scope of protection of the utility model.
1. An engine fuel injection pump return oil pipe is characterized in that the oil pipe extracted upward from the oil injection pump return hole and the oil tank nozzle connected with the oil pipe, and the oil injector return oil pipe is connected by the connection of the oil pipe and the oil tank nozzle.
2. According to claim 1, the engine fuel injection pump oil return pipe is characterized in that the oil pipe is drawn vertically upward from the oil return hole of the fuel injection pump.
3. According to claim 1 or 2, the engine fuel injection pump return pipe is characterized in that the upper end of the oil pipe is installed with a tee joint, and the oil tank nozzle and the oil injector return pipe are connected with the oil pipe through the tee joint.
The utility model discloses an engine fuel injection pump return oil pipe. The oil return pipe of the engine fuel injection pump comprises an oil pipe drawn upward from the oil return hole of the fuel injection pump and a fuel tank nozzle connected with the oil pipe. The oil return pipe of the fuel injector is connected by the connection point of the oil pipe and the oil tank nozzle. Due to the addition of an oil pipe from the oil return hole of the fuel injection pump to the oil return pipe of the engine fuel injection pump, part of the oil return pipe is always retained in the oil return pipe of the fuel injection pump to seal the oil pipe during the oil return process of the fuel injection pump, so that the oil return pipe of the fuel injector cannot be directly connected to the oil return hole of the fuel injection pump, preventing the air in the oil return pipe of the fuel injector from entering the engine fuel injection pump, and affecting the pump oil performance of the fuel injection pump. Which in turn affects the start of the engine.
