Shaanxi Automobile Delong F2000 After starting, the speed can be increased for a while? 5

You should go to the special maintenance center to debug the oil supply computer.

The EFI fuel supply technology adopted by Shaanxi Gas Delong will automatically control the fuel supply when idling for refueling, so as to protect the engine from running at a certain speed. If the power is not triggered when the load is heavy, it is considered normal.

There are many factors that cause the speed of the car fuel pedal not to go up, if there is a fault instrument, you can read the fault code of the car, and then know which module of the car reports the fault code, and then you can deal with the fault module.

Determine the reason why you can't speed up when you press the accelerator to the end.

Try to judge that there is a problem with the accelerator pedal of the car, because when you step on the accelerator, the cable will drive the throttle, that is, the throttle, there is a position sensor on the throttle, and the control unit knows the opening of the throttle according to the throttle position sensor signal, and then calculates the corresponding signal voltage, and finally calculates the fuel injection of the vehicle according to the single pressure of this signal.

Therefore, if the throttle position sensor is too dirty or the voltage is out of balance, it will lead to the failure of the electronic throttle, and the throttle will not be able to go up at the end speed.

My Shaanxi Automobile is also this problem today, the speed of the gas pedal can only reach 1500, the speed of the throttle is not responding, the speed of the gear walking and stepping on the accelerator can only reach 1500, the ignition is good again, the length of time is not necessarily, sometimes you can drive for several hours, sometimes you can drive for half an hour.

Is the metering unit broken? There is also a rail pressure sensor, and there is a common rail pipe to see if there is oil return? Or it is the fault of the injector, the injector fault computer can not be found, can only disassemble the oil pipe, see the amount of oil return, which cylinder is the largest oil return is which cylinder!

Your car has started the limp home function, mainly because of the following important sensors and actuators: accelerator pedal position sensor, rail pressure sensor, camshaft crankshaft position sensor, metering valve. This includes the sensor itself as well as wiring issues.

Delong F2000 heavy car when the car has no energy, lack of power, high-end does not go up to cut abnormal bumps! The oil circuit oil head gearbox has basically been checked except for not dismantling the engine! I don't know why! The master helps to find the problem! Thank you! Urgent!

Haruhei: I would also like to add that if the diesel filter is not replaced for a long time, the injector will not be able to refuel, especially when it is under heavy load.

Summary. Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Shaanxi Automobile Delong's speed went up, but the speed couldn't go up.

Hello, in this case, you need to test the following aspects: 1, check the source and test the engine data flow to see if the rail pressure data can reach greater than when accelerating, and then connect a diode test light to detect whether the pulse signal voltage of the fuel injector and the high-pressure hand pump metering unit to the engine computer version is appropriate, and see if the diode test light can be lit.

3. Check whether the urea injection nozzle is blocked, and whether the pin voltage of the urea injection unit is appropriate.

China VI new car. Is there a fault with the whole car scan**?

I haven't been to the service station yet.

If it's a new car, it's a problem with the electronic control unit or electronic control system.

Summary. Hello dear, I'm honored to answer for you <>

Shaanxi Automobile Delong car speed to 1500 rpm can not add oil, in this case, you need to detect the following aspects: 1, test the engine data flow to see if the fuel rail pressure data can reach greater than the acceleration, connect a diode test light to detect the fuel injector and high-pressure pump metering unit to the engine computer version of the pulse signal voltage is not appropriate, to see if the diode test light can be lit.

Shaanxi Automobile Delong car speed to 1500 rpm can not be refueled.

Hello dear and hungry, I'm honored to answer for you <>

Shaanxi Automobile Delong car speed to 1500 rpm plus the year slip back to the oil in this case, you need to test the following parties to bury the surface 1, test the engine data flow to see if the fuel rail pressure data can reach greater than the acceleration, connect a diode test light to detect whether the pulse signal voltage of the fuel injector and the high-pressure pump metering unit to the engine computer version is appropriate, and see if the diode test light can be lit.

I hope it will be helpful to you: The EFI fuel supply technology used by Shaanxi Gas Delong will automatically control the oil supply operator when idling for refueling, so as to protect the engine from running at a certain speed. If the power is not triggered when the load is heavy, it is considered normal.

There are many factors that cause the speed of the car fuel pedal not to go up, if there is a fault meter, the jujube file can read the fault code of the car, and then know which module of the car reports the fault code, and then the fault module can be processed.

Still have questions? Kiss, can you talk about it specifically? Or is there anything you'd like to talk about? <>

There are several main reasons for high idling:

1. The idle switch is not closed;

2. The idle control valve has lead judgment fault;

3. Air intake pipe leakage;

4. The gas distribution phase is wrong;

5. Injector dripping or nucleus blockage;

6. The exhaust system is blocked;

7. The EGR valve is opened when idling.

Solution: 1. Adjust or replace the throttle position sensor;

2. Clean or replace the idle control valve, and use a special decoder to set the idle speed;

3. Find the leakage, reseal it or replace the relevant parts;

4. Check the timing mark and readjust the gas distribution phase according to the standard;

5. Clean the cong excavation, check the amount of fuel injected by each injector and confirm that there is no blockage and dripping;

6. Replace the three-effect catalytic converter;

7. Eliminate the carbon deposits on the EGR valve or replace the EGR valve.
