The speed of the Transit diesel car has come up, but the speed can t be raised, what s going on? 10

1. The reason for the clutch.

Park the car in a flat place that does not affect other vehicles and put the handbrake on it.

When the car is working, tighten the handbrake to make sure the car is braked. After that, start and step on the clutch.

Hang in first gear. Refuel while releasing the clutch, under normal circumstances, the engine of the vehicle should be turned off. If the engine is not turned off and the engine speed is still high, it means that the clutch is not working.

2. The reason for the clutch pump.

In addition, if the car has a clutch pump, check the oil return of the pump and the oil return of the booster.

3. The reason for the air intake system.

It should be judged whether the air intake system is in good condition, and if it is in good condition, the air filter should be thought of whether the air intake system needs to be cleaned.

Remove and blow off the dust, if it is difficult to blow it off, it should be replaced.

4. Throttle reasons.

Check if the throttle is clean, further check the intake valve, intake manifold. Wash properly if necessary.

5. Automatic transmission reason.

A road test can be done to determine if the automatic transmission is faulty, and the joystick can be dialed into a different position to let the car go. If an automatic transmission.

Move up to a certain gear.

When the engine speed suddenly increases, but the speed does not increase accordingly, it means that there is slippage in this gear. The more likely the engine speed to increase during skidding, the more severe the skidding.

6. Automatic transmission hydraulic oil.

Causes. Check the oil level height of the hydraulic oil of the automatic transmission, if the oil level height is too low or too high, you should find a good adjustment, and then see if the automatic transmission is still slipping. If it is still slippery, then the quality of the hydraulic oil should also be checked, if the hydraulic oil is brownish-black or has a burning smell, it means that the friction pads or brake bands of the clutch or brake are burned, and the automatic transmission should be dismantled.

The speed of the diesel car is up, but the speed cannot be raised, which may be caused by the failure of the clutch plate or the gear is too low.

Let's first analyze the fault phenomenon that may cause this situation:

Fault phenomenon 1: when you press the accelerator pedal when starting, the engine speed increases quickly but the speed increases slowly;

Fault phenomenon 2: When pressing the accelerator pedal to accelerate while driving, the engine speed increases but the vehicle speed does not increase quickly;

Fault phenomenon 3: The flat road driving is basically normal, but the uphill slope is weak, and the engine speed is very high.

Once you understand the fault phenomenon, you can determine the cause of the failure.

If you are driving a manual transmission car, you must pay attention to the clutch plates, which may be due to damage to the clutch plates and the speed of the vehicle cannot be increased. If you are driving a car with automatic transmission, it is generally caused by damage to the friction plates in the transmission. In addition, if the oil pump is worn too much or the main oil circuit is leaking, resulting in too low oil pressure in the oil circuit, it will also lead to this fault phenomenon.

At this time, do not accelerate anymore to avoid greater economic losses. The vehicle should be driven to the maintenance shop for maintenance in time.

The tires or clutch plates are too badly damaged, if it's okay, it is estimated that there is a problem with the ABS, and it needs to be checked.

When the water tank is dirty and the ignition is not improper, it will slip due to the high water temperature, whether the clutch plate is changed, and the clutch adjustment is too high.

Probably:1The gear is too low.

2.Clutch friction plate slippage.

1. The oil pressure is not enough, and the oil pump works poorly. The oil filter or grease nipple is clogged.

2. The clutch part is faulty. A cold car may be better, but as the temperature rises while driving, there is a greater chance of frequent occurrences or even "stopping" driving.

3. Throttle body department, stuck or stepper motor failure.

4. The exhaust part or contact catalysis is blocked.

5. The electrical circuit is open or short-circuited, and the conduction is poor.

Some small-displacement turbocharged engines.

In the usual constant speed driving conditions, the turbocharger is in a negative pressure state, in the foot throttle rapid acceleration, in order to obtain greater output power, the pressure relief valve of the turbocharger will be closed to achieve pressure storage, the pressure storage is the need for a certain speed to make the exhaust form an effective pressure, which takes a certain amount of time, at this time will also lead to the engine speed rise, but the power output is not large.

Because the AT gearbox uses a hydraulic torque converter to buffer and transmit power, the locking clutch inside the hydraulic transmission system is in a disengaged state when changing gears, and the purpose of this is to cushion the impact.

At this time, the power is transmitted through the gearbox oil, at the moment of sudden change in speed, the pump wheel and the turbine of the gearbox oil can not form a coupling, and the power can not be effectively transmitted to the gearbox, which will also lead to the increase of engine speed and poor power response of the car.

Note: Automatic vehicles are protected and interlocked against dangerous movements, such as switching from D gear to R gear or P gear. Because it is dangerous to inadvertently change the wrong gears. However, it is possible to switch between D and N at will, including during driving.

Coasting in neutral gear for a long time will lead to insufficient oil pressure in the hydraulic lines in the automatic transmission, which will not only increase friction and reduce the lubrication effect, but also damage the friction plates inside the automatic transmission.

The above content reference: People's Daily Online - Winter hot cars do not need to take a long time to return to the tachometer.

I didn't see the actual car, so I just made a simple judgment. There are multiple reasons that can be caused, for reference. (Take a gasoline car as an example).

1. The oil pressure is not enough, and the oil pump works poorly. The oil filter or grease nipple is clogged.

When the K revolution should be around a hundred or so, the acceleration is not weak, and it may also be a failure of the clutch part (oil or wear). A cold car may be better, but as the temperature rises (driving), there is a greater chance of frequent occurrence, or even "stopping" the driving (** when it has been completely burned out).

3. Throttle body department, stuck or stepper motor failure (you have washed).

4. There is a possibility that the exhaust part or contact catalysis may be blocked (you have also washed it). It is also doubtful ... Materials, methods, and some cars have to match).

5. The electrical circuit is open or short-circuited, and the conduction is poor. Such as ignition coils, spark plugs, lines. etc.).

6. There is no real car, and there are other possibilities that cannot be ruled out. It is recommended to go to the after-sales maintenance, hello and only run 23,000 kilometers, still within the warranty.

1) Oil circuit blockage First check whether the steam filter is blocked, whether the pump pressure of the gasoline pump is sufficient, and whether the fuel injector is blocked.

2) The exhaust system is blocked, check whether there is any blockage in the three-way catalytic converter and the entire exhaust pipe.

3) It may be that the throttle has too much carbon deposit, the idle position sensor, and the air flow meter are damaged.

Summary. Hello, I am your exclusive elite technician, we promise to be attentive, careful, and attentive to answer your car questions. Hello, the speed of the transit diesel car has come up, but the speed can not be raised, this situation is that the inside of your gearbox is slipping, the reasons are as follows, the first is that the gap between the solenoid valve and the valve body inside your gearbox is too large, resulting in the gearbox pressure relief, and the second is that the friction plate inside your gearbox is seriously worn and skidd.

The third word is that you don't change the transmission oil for a long time, it's too dirty, and the oil circuit plate of the transmission is blocked. In this case, it is recommended that you first change the transmission oil to see if it can be improved, if it cannot be improved, you need to remove the gearbox for overhaul, and the cost is generally about 4500.

Summary. Hello.

The supply of fuel directly determines the strength of power, and the full combustion of fuel and the amount of fuel are the guarantee of power, so when the power is insufficient, it is still necessary to test the fuel supply system. First of all, it should be ensured that the oil meets the fuel standard of the car, and in the case of checking the integrity of the oil circuit and connection, check whether the fuel filter, fuel injector and fuel pump are not smooth in oil supply, and clean or replace them if necessary, so as to remove carbon deposits. If acceleration is still weak, consider fuel pressure regulators, cold-start injectors, and other oil circuit components.

The Transit diesel fault light is on, and the oil cannot be added, and the speed cannot be given.

Hello, dear, your question has been received, sort it out Please wait for a while, reply to you in about 5 minutes, please be patient

Summary. Hello, happy to answer your <>

The speed of the Ford Transit diesel is too low to establish the oil pressure, first replace the diesel filter, oh, if not, replace the high-pressure oil pump. The starting speed of the vehicle is too low and can be alleviated by adjusting the throttle opening adjustment screw, but the actual adjustment of the idle speed is more complicated.

The Ford Transit diesel revs too low to build up oil pressure.

Hello. Rail pressure 300

Nozzle replacement of the old one.

The solenoid valve of the large pump has also been replaced.

Hello, happy to answer your <>

The speed of Fuhuai Naidaite Transit diesel is too low to establish oil pressure, first replace the diesel filter element, oh no, if you don't call it, replace the high-pressure oil pump. The starting speed of the vehicle is too low, which can be alleviated by adjusting the throttle opening and adjusting the spiral lead smart nail, but the actual adjustment of the idle speed is more complicated.

Kiss,**Received. It's the oil-water separator sensor that is faulty.

Kiss,**Received. 1.The solution to a faulty oil-water separator sensor is to drain the stagnant water.

After the oil-water separator is used for a period of time, there will be water accumulation in the internal land, which will cause the fault light to be lit up early. It is necessary to unscrew the drain valve of the oil-water separator to drain the water inside and lower the liquid level below the sensor. 2.

The repair line is full of water and the fault light is still on, which is a sensor problem of the oil-water separator Oh Use a multimeter to test the sensor voltage.

Dear, the rail pressure of 300 is normal, and the standard value of the rail pressure is 300 400bar.

Kiss, okay, you drain the stagnant water first. Repair lines.

Kiss, okay. You should do what the teacher tells you first.

Expansion: The idling speed of the car is not a speed, but a working condition with the ant. When the engine is idling, it is called idling. When the engine is running dry, the accelerator pedal is completely relaxed, and the engine is in the idle state.

Summary. Hello, the solution is as follows: 1. The tightness of the belt is not enough.

When the tightness of the engine belt is not enough, the engine will produce squeaky noise during work, which will seriously affect the driver's driving experience. Solution: Adjust the tightness of the engine belt.

2. The oil condition is wrong. Solution: You need to change the oil.

3. There is a leak in the intake and exhaust pipes. When there is a leak in the intake and exhaust pipes, when the engine is started, the gas will leak from the leak when the intake and exhaust pipes are intake, causing vibration and noise. Workaround:

Check the intake and exhaust pipes and replace the intake and exhaust pipes. 4. Poor fuel quality. When poor-quality fuel is used, combustion in the engine will deteriorate, causing the engine to vibrate violently and make noise.

Solution: Replace with better-quality, higher-grade fuel. 5. Abnormal engine noise.

If the screws of the lower guard plate of the engine are loose, the engine cannot be fixed, and it will shake violently and produce noise when working. Solution: Tighten or adjust the engine lower guard screws.
