Detailed Description

Fig. 1 is a schematic structural view of a fuel recovery system of a fuel system for a vehicle according to an embodiment of the present invention. Fig. 2 is a schematic view of a connection of a recovery device of a fuel recovery system for a fuel system of a vehicle to a two-way valve according to an embodiment of the present invention. As shown in fig. 1 and 2, the present invention provides a fuel recovery system for a fuel system of a vehicle, the fuel system including a filter 11, a fuel rail 12 and a fuel pipe 13 for connecting the two, the fuel recovery system including a recovery device and a two-way valve 21. The recovery device is connected with the oil pipe 13 through a pipeline 22 and is used for recovering and storing the gasoline in the oil pipe 13 and the filter 11 or sending the gasoline back to the oil pipe 13. A two-way valve 21 is provided in the duct 22 for controlling opening and closing of the duct 22.

According to the scheme of this embodiment, through adding in oil pipe 13 between filter 11 and oil rail 12 in original fuel oil system and establishing fuel recovery system for collect the petrol in filter 11 and oil pipe 13 when needing to change fuel oil system spare part, with avoid causing petrol extravagant, and because of the injury that petrol high-pressure injection caused the maintenance personal and because of the conflagration that petrol injection arouses, guarantee maintenance personal's safety in the maintenance process. When the gasoline needs to be collected, the gasoline can be collected into the recovery device, and then the gasoline in the recovery device can be returned to the oil pipe 13, so that the gasoline can be better saved, and the contribution to energy conservation and emission reduction is made.

During operation of the vehicle, gasoline stored in a fuel tank 14 is pumped by a fuel pump 15 and filtered by a filter 11 to a fuel rail 12 to provide power for operation of the vehicle.

As shown in FIG. 2, in one embodiment, the recovery device includes a recovery tank 23, a piston 24, and a drive mechanism (not shown). A recovery tank 23 is connected to the pipe 22 for storing gasoline. A piston 24 is movably disposed in the recovery tank 23, the piston 24 dividing the recovery tank 23 into two parts which are not communicated with each other, and a part adjacent to the pipe 22 communicating with the pipe 22 for storing gasoline. The drive mechanism is connected to the piston 24 for moving the piston 24 in the recovery tank 23. The double-headed arrows in fig. 2 indicate the direction of movement of the piston 24, and the piston 24 has a top dead center at the end of the recovery vessel near the duct 22 and a bottom dead center at the opposite end of the recovery vessel 23, respectively. When the vehicle normally runs, the piston 24 is positioned at the top dead center, no gasoline is in the recovery container 23, and when the fuel recovery system works, the driving mechanism drives the piston 24 to move towards the other side until the gasoline in the filter 11 and the oil pipe 13 is completely recovered or the piston 24 stops moving after moving to the bottom dead center.

In one embodiment, as shown in fig. 1, the fuel recovery system further comprises a pressure sensor 26 disposed in the tubing 13 for monitoring the pressure in the tubing 13.

In one embodiment, the fuel recovery system further comprises a controller 25 connected to the drive mechanism for controlling the drive mechanism to move the piston 24 within the recovery tank 23. The controller 25 is also connected to the pressure sensor 26 and receives the pressure monitored by the pressure sensor 26. Controller 25 is configured to control piston 24 to move to the side away from conduit 22 when gasoline recovery is desired or to control piston 24 to move to the side of conduit 22 when gasoline return is desired, controller 25 being further configured to control the rate at which piston 24 moves based on the pressure monitored by pressure sensor 26.

Alternatively, the drive mechanism and the controller 25 are connected by a wire harness. In other embodiments, the drive mechanism and controller 25 may be connected by wireless signals. In practical applications, the driving mechanism may be controlled by a mechanical principle or by a hydraulic method.

In one embodiment, as shown in fig. 2, the recycling container 23 has a plug 28 for connecting a wire harness on the outer wall of the recycling container opposite to the conduit 22, and the plug 28 is used for connecting the wire harness. The pipe 22 is connected to the oil pipe 13 via a pipe connector 29 provided at the opening of the pipe 22.

Preferably, the two-way valve 21 is a pressure valve and is configured to open when the pressures on both sides thereof are different and close when the same. In one embodiment, the two-way valve 21 is configured to open when the piston 24 is moving and close when it is stopped. During normal operation of the vehicle, the piston 24 is not moved, so that the pressure on both sides of the two-way valve 21 is the same, and therefore there is no force that can open the two-way valve 21, at which time the two-way valve 21 is closed and no gasoline flows into the recovery device. When gasoline is collected, the piston 24 moves to a side far from the pipe 22, so that the pressure of the side of the two-way valve 21 close to the oil pipe 13 is higher than that of the other side, and at this time, the two-way valve 21 is opened, and the gasoline smoothly flows into the recovery container 23. When returning the gasoline, the piston 24 moves to one side of the pipeline 22, so that the pressure of one side of the two-way valve 21 close to the oil pipe 13 is lower than that of the other side, and the two-way valve 21 is opened at the same time, and the gasoline is smoothly returned.

In a preferred embodiment, as shown in fig. 2, the fuel recovery system further comprises a switch 27, manually operable, connected to the controller 25 for controlling the direction of movement of the piston 24. The switch 27 can be set to two positions, first and second. When the whole vehicle needs to replace fuel supply parts, the switch 27 is shifted to the first gear, the controller 25 controls the piston 24 to move in the direction away from the pipeline 22 so as to suck the gasoline into the recovery container 23, meanwhile, the pressure sensor 26 monitors the pressure in the oil pipe 13, the controller 25 adjusts the movement speed of the piston 24 according to the pressure condition in the oil pipe 13 so as to prevent the pipeline pressure negative pressure from damaging other parts until the piston 24 runs to the bottom dead center or the gasoline is completely recovered, the controller 25 stops the movement of the piston 24, so that the gasoline in the oil pipe 13 is stored in the recovery container 23, and the problems of fuel leakage and the like do not exist when the parts are replaced. After the replacement is finished, the switch 27 is shifted to the second gear, the controller 25 controls the piston 24 to move towards the pipeline 22, the gasoline in the recovery container 23 is returned to the oil pipe 13, meanwhile, the pressure sensor 26 monitors the pressure in the oil pipe 13, the controller 25 adjusts the movement speed of the piston 24 according to the pressure condition in the oil pipe 13, so that the situation that the positive pressure of the pressure in the oil pipe 13 is too large to damage other parts is avoided, the piston 24 moves to the top dead center, the controller 25 stops the movement of the piston 24, the fuel is returned to the oil pipe 13, and the starting time of the engine is shortened.

In particular, the invention also provides a vehicle comprising a fuel recovery device for a fuel system of the vehicle. The gasoline in the filter 11 and the oil pipe 13 can be collected when the parts of the fuel system need to be replaced, so that the waste of gasoline, the damage to maintenance personnel caused by gasoline injection and the fire caused by gasoline injection are avoided.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
