What is the reason for Chang an Ounuo s inability to climb the slope

There are many reasons for insufficient power, the common ones are insufficient fuel pressure, poor ignition energy, air flow, intake pressure signal is wrong, and exhaust is blocked! Large engine wear, insufficient cylinder pressure, valve timing deviation, poor fuel quality, etc. will cause the engine to be weak, it is recommended that you go to a professional place to check! [If you have a problem with the car, ask the car master.]

1st gear is too high, you should change to low gear when climbing....2. The reason for the change of motor vehicle to gas, the climbing from gas to gasoline, I believe it will be much faster....3. The reason why the belt speed is too low and the belt speed is unstable.

It is recommended that if you are an older car, you should choose gasoline whether it is on a low-speed road or a highway.

Your car situation should be checked from two points, first of all, you should observe how the engine tachometer speed rises slowly when the acceleration speed of the vehicle is normal driving, and the difference in engine speed is divided into two reasons, one is that the engine tachometer rises slowly, which mainly reflects the engine dynamics problem. This problem comes from many reasons, without too much elaboration, the second engine speed rises quickly but the speed is slow, which can directly reflect the problem of clutch components.

Summary. Hello, dear, the vehicle has a speed up and can't jog up this fault performance, it is recommended to check the following reasons for the failure:

First, the shaking or inability to speed up caused by carbon deposition in the vehicle engine, in this case, it is recommended to clean the carbon deposition in the throttle and intake tract, and then check the carbon deposition in the cylinder and whether the carbon deposition in the valve base is serious.

Second, the engine ignition system failure, this failure is generally caused by the ignition coil, or the aging of the spark plug, corresponding to the replacement of the damaged ignition coil, or the replacement of the spark plug.

Third, if the engine fuel system fails, the oil circuit is too dirty, or the fuel quality is too poor, it is recommended to clean the oil circuit, and then add some high-grade gasoline, or fuel treasure.

In the last case, it is considered that it is caused by the problem of the vehicle's gearbox, the internal friction plate of the gearbox is worn, or the solenoid valve body has been damaged, and the upshift is not timely or the acceleration is weak. The gearbox needs to be checked.

Hello, dear, the vehicle can not run up in a gear to speed up this fault performance, it is recommended to check the following aspects of the fault causes: first, the engine of the vehicle caused by carbon deposition caused by the shaking or speed up weakness, in this case, it is recommended to clean the throttle and intake tract carbon deposition, and then check the carbon deposition in the cylinder, whether the valve base carbon deposition is serious. Second, the engine ignition system failure, this failure is generally caused by the ignition coil, or the aging of the spark plug, corresponding to the replacement of the damaged ignition coil, or the replacement of the spark plug.

Third, if the engine fuel system fails, the oil circuit is too dirty, or the fuel quality is too poor, it is recommended to clean up the oil circuit in the sleepy shirt, and then add some high-grade gasoline, or fuel treasure. In the last case, it is considered that it is caused by the problem of the vehicle's gearbox, the internal friction plate of the gearbox is worn, or the solenoid valve body has been damaged, and the upshift is not timely or the acceleration is not delayed. The gearbox needs to be checked.

There are several reasons why you can't start in 1st gear:

1.Pay attention to the battery: Now the car is commonly used maintenance-free battery, and it is also necessary to regularly look at the power display inside:

Under normal circumstances, green means that the power is normal, white means that the battery needs to be charged and maintained, and red means that the battery is out of power (some indicate this: green means qualified, black means power loss, and white means that the battery is damaged and needs to be replaced). The lifespan of the battery is generally about two years.

If the battery level drops, it should be replaced in time.

2.Pay attention to the throttle valve body and idle valve: the throttle valve body and idle valve are difficult to start due to carbon stagnation, if the vehicle using the idle valve can lightly step on the accelerator and start again, it can catch fire, but the oil will be turned off immediately, so it is best to go to the repair shop in time to do a cleaning and overhaul.

In addition, when doing maintenance, we must change the air filter element frequently, and the air filter should be replaced every 10,000 kilometers if it is a sandy bucket Zen soil road.

3.Fuel pressure: In order to ensure the normal start of the engine, the residual oil pressure of the fuel system after the engine is turned off cannot be lower, otherwise the fuel injector will not be able to inject enough fuel to ensure the start if the pressure is insufficient.

At this point, if the ignition is turned on repeatedly, the fuel pressure will return to normal, and the start will be much easier. But it's best to find a professional maintenance person to check the fuel system and troubleshoot.

4.Lubricating oil quality: In winter, all kinds of lubricating oil should be replaced in time, including engine oil, transmission oil, steering empty dust booster oil, etc., because the viscosity of ordinary lubricating oil increases in winter and the fluidity becomes poor, resulting in increased friction resistance when the parts move, and it is difficult for the engine to start cold.

Choose an oil with a slightly lower viscosity to reduce mechanical wear and protect the engine.

1. The run-in of the new car has not yet ended, and the internal resistance of the engine is large, which consumes a lot of power.

2. Add too much oil, resulting in large internal resistance, and release excess oil.

3. Insufficient throttle opening, blocked air filter, etc.

4. The brake is stuck.

5. The three-way catalytic converter is blocked.

6. Check the cylinder pressure for old cars, and eliminate faults such as poor valve closure and cylinder bed leakage.

When idling, the engine shuddes and revs unevenly. The reasons are: blockage of the idle air measuring hole, poor working of the idle device, weak sparks of individual cylinder spark plugs, poor sealing of individual valves, air leakage of the intake manifold, too early or late ignition time, improper idle speed adjustment, etc.

When the engine idle speed is unstable, the idle speed should be adjusted first, if the fault cannot be eliminated after the idle speed adjustment, the idle speed measuring hole and the idle air measuring hole should be checked to see if it is blocked.

Hello! This is the idle instability, cleaning the throttle, checking the idle motor, and the intake pressure sensor. I hope it can help you, and I wish you a happy car! Thank you!

My Ou Nuo is the same, I bought a g idle appliance for 18 yuan on ** and spent 10 minutes to replace it myself, and now everything is very normal.

Hello, it is recommended that you clean the throttle and idle motor, if it is dirty, it will cause the throttle and idle motor to hairpin, if you can solve it, it may be that the idle motor is broken, you need to read the fault code of the decoder for troubleshooting, the working hours of cleaning the throttle are generally about 50-80, I hope my answer will be helpful to you.

The same goes for my Ouno. I bought an idle motor at **18 yuan, and it took 10 hours to replace it myself. Everything works fine now.

Solved no, mine is also this problem.

Wuling Hongguang can also be transferred to the 4S store.

Summary. Hello, in this case, I suggest you clean the throttle body, which is mainly caused by throttle body stagnation.

Changan Ounuo throttle is unstable, and often the throttle goes up by itself when it doesn't move, what should I do?

Hello, in this case, I suggest you clean the throttle body, which is mainly caused by throttle body stagnation.

After cleaning, the speed motor was replaced.

Oil problems can also cause.

If the oil pressure of the oil pump is insufficient, it can be known that the violent noise can not be refueled for a long time, resulting in aging and damage before the oil pump lifting cover, it is recommended to replace the oil pump, or the fuel filter element is blocked and the fuel injector is blocked and leaked.

If the fuel filter element is blocked or leaking, it will also lead to insufficient fuel, and if you step on the accelerator and rush to the town, it is recommended to replace the fuel filter element and test the car to see if it is normal. The fuel filter element usually filters large particles of impurities in gasoline, which can improve the quality of gasoline oil, and is generally replaced once every 1-2 years.
