As shown in Figure 1, an embodiment of the present invention proposes an emergency fuel supply system for an engine 4, which includes: a fuel tank 11 and an emergency fuel tank 1; the fuel tank 11 passes through a first oil inlet pipeline 10 and a first return The oil pipeline 8 is connected to the engine 4. The emergency oil tank 1 is connected to the first oil inlet pipeline 10 through the second oil inlet pipeline 5. The emergency oil tank 1 is connected to the first oil return pipe through the second oil return pipeline 2. Road 8 is connected, and the horizontal position of the emergency oil tank 1 is higher than the horizontal position of the engine 4 .

The utility model adds an emergency fuel tank 1 and improves the fuel pipeline of the engine 4. By setting the emergency fuel tank 1 at a position higher than the engine 4, the inlet and return pipes of the emergency fuel tank 1 are connected to the main inlet and return pipes close to the engine 4. Provide oil supply to the engine 4 in a "bottle-type" manner. Therefore, even if the vehicle is parked for a long time, the fuel will not flow back to the higher emergency fuel tank 1, and air bubbles will not be generated on the inlet and return lines of the emergency fuel tank 1, allowing the vehicle to start smoothly. In addition, even if there is no fuel in the fuel tank 11, the emergency fuel tank 1 can be used to supply fuel to the engine 4, ensuring timely operation and improving user experience.

It can be understood that the capacity of the emergency fuel tank 1 is smaller than the capacity of the fuel tank 11. For example, the capacity of the emergency fuel tank 1 can be set to a fuel capacity that can run about 100 kilometers according to the situation.

As shown in Figure 1, the first oil inlet pipeline 10 is provided with a first solenoid valve 9 for switching the pipeline, and the first oil return pipeline 8 is provided with a second solenoid valve 7 for switching the pipeline. The second oil inlet pipeline 5 is provided with a third solenoid valve 6 for opening and closing the pipeline, and the second oil return pipeline 2 is provided with a fourth solenoid valve 3 for opening and closing the pipeline.

Further, the connection position of the second oil inlet pipe 5 and the first oil inlet pipe 10 is located on the first oil inlet pipe 10 between the first solenoid valve 9 and the engine 4; The connection position of the second oil return pipeline 2 and the first oil return pipeline 8 is located on the first oil return pipeline 8 between the second solenoid valve 7 and the engine 4 . Through the arrangement of the four solenoid valves and the connection positions, it is possible to reasonably control which fuel tank (fuel tank 11 or emergency fuel tank 1) is used to supply fuel to the engine 4, and when there is no fuel in the emergency fuel tank 1, the fuel can be replenished in time.

As shown in Figure 1, the emergency oil tank 1 is provided with a liquid level sensor. The liquid level sensor is installed on the inside of the tank wall of the emergency oil tank 1 for real-time monitoring of the oil volume of the emergency oil tank 1. As shown in Figure 2, the liquid level sensor is electrically connected to the electronic controller unit (ECU) of the vehicle, and sends the amount of oil in the emergency fuel tank 1 to the ECU. The electronic controller unit is also electrically connected to the engine 4 speed sensor and the emergency starting switch. The emergency start switch is installed in the cab. The ECU collects signals from the emergency switch, engine 4 speed sensor and emergency fuel tank 1 liquid level sensor, and controls the actions of the four solenoid valves according to the calibrated operation logic. The ECU automatically controls the emergency system to realize its functions.

The specific working method is shown in Figure 3:

When the engine 4 is difficult to start after being left for a long time or the fuel tank 11 (main fuel tank) is short of oil and cannot operate, the driver can turn on the emergency starting switch, the ECU receives the instruction, the emergency fuel pipeline starts to operate, and the ECU controls the first solenoid valve 9 and The second solenoid valve 7 is closed, the fourth solenoid valve 3 and the third solenoid valve 6 are opened, the fuel pipeline is changed to supply fuel to the engine 4 from the emergency fuel tank 1, and the engine 4 can start smoothly. After the engine 4 is started, the driver can choose to close the emergency fuel tank 1 or continue to use the emergency fuel tank 1 according to the actual situation.

Situation 1: When there is oil in the main fuel tank and the engine 4 is operating normally, the emergency switch can be turned off. At this time, the ECU controls the first solenoid valve 9 to open based on the emergency switch and the engine 4 speed signal. At this time, the oil supply state is that the main oil tank and the emergency oil tank 1 jointly supply oil. After running for a certain period of time, the third solenoid valve 6 is closed. At this time The fuel supply status is switched to supply fuel to the main fuel tank, and the fuel return continues to fill the emergency fuel tank 1. When the specified amount of fuel is filled, the liquid level sensor of the emergency fuel tank 1 will send a signal to the ECU, and the ECU controls the second solenoid valve 7 to open , the fourth solenoid valve 3 is closed, and the fuel pipeline is switched to return fuel to the main fuel tank. At the same time, the emergency oil tank 1 maintains the prescribed liquid level for next use.

Situation 2: When there is no oil in the main fuel tank 11, the driver can continue to use the emergency fuel tank 1 until the car is driven to a gas station or maintenance station. When the oil is filled or repaired, the emergency oil tank 1 is turned off after starting normal operation. The system proceeds with the steps after turning off the emergency switch in case 1, so that the emergency oil tank 1 is automatically filled to the set level for next use.

The system also has the function of automatically detecting the level of emergency fuel tank 1 and filling it with oil. When the engine 4 starts, the liquid level sensor of the emergency oil tank 1 will self-check. When the ECU detects that the liquid level of the emergency oil tank 1 is insufficient, it will automatically open the fourth solenoid valve 3 and close the second solenoid valve 7. At this time, the oil return state switches to Fill the emergency oil tank 1 with oil. When the liquid level in the emergency oil tank 1 reaches the specified level, the EUC controls the second solenoid valve 7 to open and the fourth solenoid valve 3 to close according to the liquid level sensor signal, and the oil volume returns to the main oil tank supply and Return oil. In this way, the emergency fuel tank 1 always maintains a set amount of fuel, providing safety guarantee for emergency use.

The oil supply system of the present utility model has a simple structure and is easy to install, and can effectively solve the problem of difficult starting of the engine 4 and emergency oil supply without making major changes to the entire vehicle. And it is easy to operate. The driver only needs to press the switch and the ECU can automatically control it to realize the function. At the same time, the ECU can automatically detect the liquid level of the emergency fuel tank 1, automatically fill it and maintain the specified liquid level, avoiding manual operation, preventing forgetfulness, and ensuring that there is emergency fuel every time.

Based on the above emergency fuel supply system, embodiments of the present invention also provide a vehicle, which is provided with the emergency fuel supply system described in the above embodiment. Since the above emergency fuel supply system has the above technical effects, the emergency fuel supply system is adopted. Please refer to the above embodiments for the technical effects of the vehicle's fuel supply system.
