Why is there a sizzling sound when stepping on the accelerator while driving?

There is an abnormal sound when you step on the accelerator, and it may be the sound of the oil pump or related places. Or maybe the release bearing of the clutch is broken.

In addition, the sizzling sound depends on where it happens. On the right side of the engine is generally the belt of the generator; The words on the left are a matter of festival atmosphere; The presence of front brake pads may be mostly due to brake calipers, and a small number of them are caused by jamming. It may be that when the piston of the brake caliper is pressed back when it is installed, it is crushed, resulting in a certain degree of stuckness.

Precautions for driving

Drive in one lane as much as possible, and don't change lanes too often: one in the overtaking lane and one in the driving lane. Do not change lanes frequently when driving on the highway, do not drive side by side with other vehicles, do not drive in the overtaking lane for a long time, and do not overtake from the emergency lane.

Do not make a sudden turn or brake suddenly.

At high speed, you must check the car, especially the tires, and repair the problem in time, without which your car will not be able to drive no matter how good it is. In addition, the tire pressure also needs to be monitored at all times, too low and too high tire pressure will cause potential safety hazards to the vehicle.

It's the two nuts of the front drive shaft that are loose, and it's good to go to the repair department tightly, and I don't have such a tool.

There are several reasons for this.

1. The engine has abnormal noise.

Symptom description: There is a lot of abnormal noise in the engine compartment, and most people also judge it to be the abnormal noise of the engine compartment by the sound**, which is usually a metal screeching sound or a howling sound.

2. There is abnormal noise in the gearbox.

Symptom description: If there is a "rustle" sound inside the gearbox while the car is driving, and there is no more after pressing the clutch or accelerator, there will be a whistle-like sound when changing gears.

3. There is an abnormal sound in the door.

Symptom description: When driving on the accelerator or brake, there is always some abnormal noise in a certain part of the body, the sound is not loud, and it does not affect normal driving, but it always makes people worry a little about the failure of the body.

1.Engine Reason:

Solution: The abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment.

Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

2.Transmission Reason:

Solution: There are many transmission parts, and the reasons for the sound are more complex, so we should pay attention to whether it is related to a specific speed, such as some planetary teeth that sound at about 50km h.

Whether it is related to certain gears, which is very important for judging the failure of the transmission, if a certain gear sounds, it must be related to the components that affect the transmission of the gear; If all gears sound, it is often a common meshing shaft failure or a lack of oil in the transmission. Whether it is related to specific actions, such as increasing and decreasing gears, starting, rapid acceleration, sharp deceleration, turning, etc., are effective means to judge abnormal noise, among them, changing speed and direction are particularly important for judging the rear axle fault.

3.Door Reason:

Solution: The abnormal noise of the door is mainly caused by the lack of lubrication, but it is necessary to determine whether it is the position of the door hinge or the glass regulator, door lock mechanism, handle mechanism, etc. inside the door. In the case of door hinges or limiters, special door hinges and slide grease can be used, while special door attachment grease is used for lubrication of glass regulators, door locking mechanisms, handle mechanisms, etc. inside the door.

Due to the fact that the car is not heated up before driving, it is generally possible to start after one minute of heating up before driving, especially when it is cold.

It is also possible that the exhaust pipe is slightly deformed and leaking, or check the air intake system for any air leaks and abnormal noises from the engine belt assembly.

It may also be the sound of the half shaft, bearing and other parts, the engine abnormal sound indicates that the technical status of a certain mechanism of the engine has changed, mainly due to the excessive wear and tear of some parts or even the assembly, improper adjustment of the cause, some abnormal noise can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the expansion of the fault, it needs to be reminded that if it is an abnormal noise in the engine, the owner is most likely unable to solve it by himself, and it is best to send it to the factory for maintenance.

The reasons for the sound of air leakage when the car steps on the accelerator are:1Broken air leakage in the intake manifold; 2.

Excessive valve clearance or loose valves. The air intake pipes of modern cars are basically made of engineering plastics, and the temperature in the cabin is usually high, and the plastic is prone to aging, resulting in air leakage in the air intake pipe. The valve works according to the opening and closing of the throttle, and the valve clearance will become larger when the valve is worn, and there will be a sound of air leakage when the throttle is pressed.

Other than that; If the car steps on the accelerator and there is a sound of air leakage, if it is a turbocharged engine, it is the sound of the turbocharger working, if it is a naturally aspirated engine, it may be that there is an air leak in a certain part of the intake pipe.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

The working sound of the grease nozzle solenoid valve, this is normal, it doesn't matter if the refueling sound becomes louder when the speed is low, it is the increase in the flow rate of the version of the fuel injection and the acceleration of the jumping frequency of the solenoid switch; However, the speed is too low to refuel and not speed up, and there is a bit of fuel consumption, it is recommended to lower one gear when you hear the sound, and the speed of the car is obviously much faster.

It is recommended to check the air conditioner belt and belt tensioner, eliminate the fault caused by aging, and replace the gram to solve the problem.

It is possible to copy the following.

Several aspects. The throttle is aging and the upper point of waste oil lubrication is below bai, du

The mechanical wear between the accelerator pedals is also lubricated with waste oil.

If the free clearance increases, just go to the repair shop to adjust it.

If the sound is in the clutch, then the wear of the clutch can be considered. Stepping on the accelerator, the vehicle does not work hard, this is a slipping phenomenon, most likely the clutch plate is thin, there is a rustling sound, it is likely that the clutch release bearing is broken.

It can also be caused by too much free clearance of the clutch.

Without a specific look, it is impossible to clearly state.

The car sometimes has a chirping sound, and the 4S shop can't be repaired well, and the 40-year-old professional technician will teach you a trick to solve it.

If your car is a new car, there are two reasons, you can check the instrument, and then look at the transmission, if there is oil stain, it will cause the transmission oil pump to have a sound; You can also see if your gasoline is knocking, mainly to check the instrument and whether the workbench is loose; Of course, the change of reputation does not rule out that your new car is going through a run-in period. If it's not a new car, you need to pay attention to this time, and here is a list of a few places that may go wrong:

1.The throttle cord is aging, you can give it a little oil lubrication.

2.There is mechanical wear between the accelerator pedals, the method is the same as above, and lubricate it with oil as well.

3.Your car's free clearance starts to increase on top of the original, in which case you can go to the garage to adjust it.

4.If the abnormal noise is in the clutch part, then you can pay attention to the wear of the clutch nuclear section, try to step on the accelerator, if the car is running normally but does not accelerate, this is an obvious slippage phenomenon, most of the clutch plates are worn thin, if there is a rustling sound, your clutch release bearing is likely to be broken.

After all, we are not professional, some situations we ourselves can not solve, you can only ask the car mechanic to give your car a repair, you must develop a good habit of driving when driving on weekdays, and cherish your car, so that your car can be with you for a longer time.

Millions of car purchase subsidies.

1.It is recommended to operate and maintain according to the maintenance manual. Regularly maintain the owner, and change the engine oil once every 5,000 kilometers. Some vehicles will.

There are hints. 2.The choice of oil should be based on the requirements of the engine, and it is not necessary to use an overly high-grade oil on a less demanding engine, nor should a lower grade oil be used on a more demanding engine.

3.Multi-grade oil should be selected as much as possible, because multi-grade oil has a good protective effect on the pure motive due to its saving, long life and high efficiency. Based on multi-grade oils.

In particular, in the process of use, there may be premature blackening of the rock, and the oil pressure is smaller than that of ordinary engine oil, which is normal.

4.The quality of some domestic brand-name engine oil is quite good, and it is much lower than that of imported similar products, so it can be used with confidence.

Whenever possible, a less viscous oil should be used to keep the oil path clear. For example, in the high temperature season or under the condition of severe engine wear, the selection of high viscosity engine oil is conducive to the formation of oil film and reduce engine wear.

The car stepped on the accelerator and there was a sizzling sound, I am an old driver, the car stepped on the accelerator and there was a sizzling sound, I am an old driver, if your car stepped on the accelerator and there was a sizzling sound, then it means that you pointed out that there was a fault in your oil potato fiber road, and you should go to the repair Weishou Fu shop 4S shop in time to check.
