After the vehicle is turned off, the start time is too long.
First, the vehicle meets the normal startup must have a certain condition, that is, there is sufficient start speed (generally 150 ~ 300R / min); there is sufficient compression pressure to achieve sufficient fire temperature; there is enough oil volume and good fog change. Second, look forward from engine oil oil roads:
1. Check if the tank vent is blocked;
2. Check if the oil tank exjects whether there is welding defect (gripping, air hole);
3. Check the rubber tube connected between the oil tank from the oil pipe to the engine into the oil pipe, which is not extruded, bending, and damage to the oil supply.
4. Check the main, the three fuel prefilter cores of the oil-in-oil end to the engine connections;
5. Check whether the prefilter is flat and smooth, smooth, and burr;
6. Check if the engine low-pressure oil pump pump transition joint has a crack or tubing nut is unbuined.
Silicone fans clutch failure
The two bolts on the fan slave are released, and the lock stop is inserted into the active shaft, fasten the bolt, but the fan speed does not change the temperature of the engine temperature, and can only be used.
Engine overheating
If the engine water temperature meter pointer is in the red area, it should be slowed down, and then quickly let the engine turn off. Follow these steps to cool the engine:
1. Check if the front protection grid is in the protection state, and go to the regular use state;
2. Open the inspection port, check whether the engine coolant in the expansion tank is insufficient;
3. Open the hood to remove all obsissive sink and oil cooler, if the air of the oil cooler and the radiator is not smooth, the engine is lubricated, and the engine cooling liquid cannot be effectively cooled;
4. Check if the radiator tube is damaged, if there is an immediate repair or replacement.
Notice
If the engine coolant horizontal line is in a low position, do not start the vehicle, otherwise the engine can be damaged.
Charging failure alarm
1. Check whether the motor drive belt loose or wear; adjust or replace the belt.
2. Check the charging load system.
3. Check if the system harness is normal.
Tank conversion valve fault handling
The fuel tank fault conversion valve fault treatment method is as follows:
Fault phenomenon | Check item | Possible cause and treatment method |
The valve conversion is normal, the oil box cannot be filled (Oil gauge indication 0) | Check the fuel tank | Oil fuel tank oil or oil is too small. |
The valve cannot be converted normally (the sound of the conversion switch does not until the valve conversion) | Check valve power supply circuit | When the valve does not switch properly: Check if the switching valve power supply loop fuse is blown; Check if the insertion connections in the wiring connector associated with the valve connection are good, plus plug-in, re-conversion test; Whether the harness connected to the valve is broken; Whether the conversion switch is damaged; Conversion valve damage; can be disassembled when the condition is permitted, check whether the valve internal movement is good, whether the contact point contact is good, whether the transmission is flexible, and the corresponding problem is processed and replaced back the power-on test. If it still cannot be converted, Conversion valve. After accurate judgment, it will be processed depending on the situation. Note: When the conversion valve is not powered, the oil gauge always indicates the amount of fuel tank oil! |
The valve conversion is normal, the fuel tank cannot be filled (the oil gauge is normal) | Check oil supply | When the oil supply oil pipeline assembly is not damaged and the fuel tank cannot be filled, it indicates that the supply oil pipe joint is not tightly connected, and a large amount of air is formed into a large amount of air in the supply oil pipeline. At this time, you must carefully check the joints of the pipelines and fastened loosely. |
When the oil supply oil pipeline assembly is damaged, the damaged oil pipe or joint is replaced. | ||
The new valve must be replaced when the valve body is injured on the valve body, causing the pipe joint connection without tight or sealing surface leakage. | ||
The valve conversion is normal, but on, downhill or bump road engine flames (oil gauge indication is normal) | Check the fuel tank | The amount of fuel tank oil is too small, in the car, deceleration, upper, downhill, or bump road travels, inhaling the air to form an airbase to turn off the engine. |
Oil tank oil level signal display failed | Check fuel tank sensor and signal line | Remove the electric wire of the corresponding tank to the oil volume sensor and intermittently touched with the frame, and observe whether the oil meter is swingable; Swing: oil volume sensor damage, replace the sensor; No response: Check the line whether it is broken, whether the conversion valve contact is poor contact, and if it is normal, replace the conversion valve. |
Check if the valve conversion is normal conversion | According to the above processing method, the processing affects the factors that the valve cannot be properly converted. |
