What is the cause of H6 indoor abnormal noise, and what is the abnormal noise of Haval H6 engine

If there is no abnormal sound in the clutch engagement, but there is an abnormal sound after pressing the clutch pedal, it may be that the front bearing of the first shaft is damaged. The reason is that when the clutch is engaged, the first shaft rotates with the flywheel, and the front bearing of the first shaft has no relative motion, so there is no abnormal sound or the abnormal sound is not obvious; When the clutch is disengaged, the first shaft is separated from the flywheel, and the inner and outer rings of the front bearing of the first shaft move relatively, and if the bearing is damaged, there is an abnormal sound. If the engine is idling and the transmission is in neutral, there is a less obvious abnormal noise in the front of the transmission, but when the car starts and shifts, the clutch is in a semi-engaged state and makes a strong metal friction sound, which is likely to cause damage to the front bearing of the first axle.

The reason is that when the car starts and shifts, the clutch is in a semi-engaged state, and the front bearing of the first axle is subjected to a large load. If the bearing is damaged, it makes a strong metal grinding sound. If there is an abnormal noise in the front of the transmission, and the abnormal noise disappears after pressing the clutch pedal, it may be that the rear bearing of the first axle and the needle roller bearing at the front of the second axle are faulty.

The reason is that after the clutch is disengaged, the rear bearing of the first shaft and the needle roller bearing at the front of the second shaft do not rotate, and the abnormal noise disappears naturally. If the operation is such as , without stepping on the clutch, tightening the hand brake, and the abnormal noise at the front is aggravated, it is the needle roller bearing at the front of the second shaft that is faulty. The reason is that the clutch is engaged, the first shaft rotates, the hand brake is tightened, the second shaft does not rotate, and the needle roller bearing in front of the second shaft must work, and if it is damaged, there must be abnormal noise.

If the operation is such as, there is a clear abnormal sound during driving, it is most likely caused by the abnormal sound caused by the failure of the constant meshing gear, as for which pair of constant gear failure, it can be judged by listening to the sound from the front to the back by the probe.

Abnormal noises can only be judged by listening to the sound during the test drive.

1. Abnormal noise of hot car: the main driver is vigilant, because it is difficult for the owner to distinguish the abnormal noise from the ** when drivingIt is best to go to the 4S store to troubleshoot the problem. When there is abnormal noise, the engine power is normal, there is no symptom of weakness, the exhaust color is also normal, and there is no blackening or whitening, which means that the problem is not very serious, and the fault in the cylinder can be ruled out.

2. Abnormal sound of cold car: When the cold car is in the car, it is common to hear the abnormal sound of "da-da" in the engine compartment, and it disappears after the hot car. This is because the car is parked for too long, the oil basically flows back to the oil pan, and the oil cannot form an effective oil film and cannot establish an effective oil pressure during the cold start.

At this time, the metal parts inside the engine collided, and there was a slight impact sound.

Common engine failures.

1. The engine is hot and the car is shaking.

The engine is hot and the car is shaking when idling. There are many reasons for the idle shake of a hot car, the most common is the lack of fire in the engine, generally check the spark plug, ignition coil, fuel injector and oil circuit, whether the exhaust is blocked, whether the fuel label is matched, remove the engine carbon deposit, whether the throttle valve is carbon deposit, whether the engine rubber block is firm, etc.

2. Engine carbon deposit.

The formation of carbon deposition is mainly due to the incomplete combustion of the engine when it is doing work, and the gelatinous substance produced by the impurities in the fuel and oil during combustion, the carbon deposition is formed over time. Carbon deposition will cause cool car engine shaking, idle engine shaking, power decrease, fuel consumption increase, starting difficulties, idle instability, poor acceleration, exhaust gas exceedance, fuel consumption and other phenomena, the solution can be alleviated by removing carbon deposition.

If the engine of Haval H6 does have abnormal noise, there may be the following reasons:

1.Large valve clearance;

2.Generator or air conditioner belt slippage;

3.Timing system abnormal noise;

4.oil quality oil problems;

5.problems with the air intake system;

6.premature ignition (diesel models do not have an ignition system);

7.burning tiles; 8.Excessive carbon deposition and so on.

The corresponding causes of different abnormal manifestations are also different, and it is recommended to confirm the specific situation after entering the station for inspection. The specific vehicle information is subject to the information published on the official website of Haval.

When there is an abnormal noise in the automobile engine, it is necessary to first determine the part of the abnormal noise and then diagnose what fault exists in that part.

There are many abnormal noises of automobile engines, such as belt abnormal sounds, valve abnormal sounds, cylinder knocking, etc.

Belt squeak is the best judgment, as long as the engine will produce a squeaky sound, then this is a belt squeak. The abnormal sound of the belt is caused by the slippage of the belt, and the solution is very simple, only need to replace the belt.

The belt is a wearable component and should be replaced every 6 to 80,000 kilometers.

Abnormal valve noise will appear on the engine, and the valve is under the valve chamber cover of the engine. There are many reasons for abnormal valve noise, which can be abnormal wear or poor lubrication.

Knock cylinders appear in the middle of the engine. Knocking is caused by an excessive gap between the piston and the cylinder wall. Knocking on the cylinder is very troublesome to repair, and the more common solution is to bore the cylinder and install a larger piston.

If there is indeed abnormal noise in the engine, there may be several reasons1Large valve clearance; 2.Generator or air conditioner belt slippage; 3.

Timing system abnormal noise; 4.oil quality oil problems; 5.problems with the air intake system; 6.

premature ignition (diesel models do not have an ignition system); 7.burning tiles; 8.Excessive carbon deposition and so on. The corresponding causes of different abnormal manifestations are also different, and it is recommended to confirm the specific situation after entering the station for inspection.

The specific vehicle information is subject to the information published on the official website of Haval.

The cam is worn excessively, and the tappet jumps during operation; 2.Excessive valve clearance due to wear or improper adjustment of the valve stem end and adjustment screw or rocker arm causes the swing arm head of the overhead valve to collide with the top of the valve; 3.excessive carbon deposition in the valve guide; 4.

The valve spring seat falls off; 5.Hydraulic tappets or tappets are damaged.

What is the abnormal noise of the car chassis.

Some diagnostic principles of chassis abnormal noise: first, understand the generation of abnormal noise (sound) - the formation of abnormal noise is vibration or vibration, and then conduct sound through air or other media, that is, there is vibration or vibration to produce sound, if the abnormal noise can be reproduced when parking, you can directly touch the ** vibration with your hand, and you can probably know the source of the sound; If it is the abnormal sound of the upper and lower swings of the two wheels, brake pads, and brake cylinders, the sound will be heard much louder outside than when the windows are closed in the car;

Secondly, if it is the abnormal sound of the ball joint of the balance bar, it will be felt in the car that when the abnormal noise is generated, the main and passenger seats will feel the vibration and noise, but the sound heard on the side that produces the abnormal sound is greater; If it is the abnormal sound produced by the steering machine tie rod, grasp a front wheel, shake the other wheel left and right, the gap will be relatively large, and the side that produces the abnormal sound is obvious when the wheel passes through the uneven road, and the steering wheel may have a certain vibration when this abnormal sound is generated (and the abnormal sound of the swing bamboo generally does not vibrate or is lighter, because the sound of the swing arm is connected in multiple places and then transmitted to the steering wheel must be weakened); If it is an abnormal sound in the inner cage, there will be abnormal sound when walking on a straight road or when turning, and sometimes there will be a very crisp sound of "click"; If it is an abnormal sound of the outer cage, the sound is most obvious when the steering is basically killed. The abnormal noise is rarely produced and the position that is difficult for the general technician to determine is the abnormal sound produced by the lower shaft of the steering machine due to the looseness, which will cause the steering wheel to shake obviously, that is, when the abnormal noise is generated, the steering wheel obviously feels the vibration with the direction of the abnormal sound, but this sound sounds much smaller on the outside than on the inside, and the diagnosis method has two aspects: one is when the left and right window glasses are lowered, when crossing the uneven road section, the sound of abnormal noise from the outside is obviously not as loud as the sound coming from the car, The sound caused by the outer ball head or swing arm is eliminated, after all, the closing of the window glass plays a certain role in sound insulation; Second, when there is an abnormal noise, the steering wheel vibrates, and the abnormal sound is significantly reduced by pressing the lower axle of the steering machine with your foot.

Hope it helps.

What is the solution to the Great Wall Haval H6 rear seat abnormal sound, and there are many factors that affect the abnormal sound of the rear seats of the Great Wall Haval H6. Presumably the sound of the owner putting something in the back seat while driving and hitting something. If it is the sound of the seat, it is recommended that the owner can try to wrap the object with iron or metal tape.

Causes and solutions to the abnormal noise of the rear seats of Haval H6: 1The rubber ball on the rope of the lid plate produces an unusual noise when it hits the wall of the box.

Solution: Use two black dovetails to clamp the drawstring above the Shentan partition. When the rubber ball is loose, it will shake downward, producing an abnormal noise.

2.The gap between the three fixing points of the rear seats is too large, causing abnormal noise. A:

The tape is wound so that it is tightly attached, and the method of applying glycerin is useless. 3.The rear seat belt buckle that connects to the body is very loose, and the abnormal noise is very serious.

Some people see this sound as the abnormal sound of the shock absorber. Answer: Wrap a thick rope between the hoops, fix the two sets of hoops and fasten the shaft.

4.The seat fixing groove is in contact with the slider of the seat. Workaround:

Clamp the pliers to the seat to solve the problem of abnormal noise of the bayonet. 5.The air filter is located on the right side of the engine cabin and is connected to a large air intake pipe.

The ordinary replacement cycle is 20,000 kilometers, and the owner can check and clean it at 5,000 kilometers. The required accessories are: a flathead screwdriver, a hexagonal socket and a Phillips screwdriver.

Millions of car purchase subsidies.

The reason for the abnormal noise when driving Haval H6 is that the tensioner wheel is worn, resulting in abnormal noise when driving; The deformation of the exhaust pipe causes abnormal noise when driving; Wheel wear causes abnormal noise when driving; Some parts of the vehicle are loose, resulting in abnormal noises when driving. Tensioner wear: The function of the tensioner is to tighten the engine belt, so that the generator set and the dynamic high return steering pump are not easy to deviate.

Due to the long working pressure and high speed of operation, the rolling bearings in the tensioner are very susceptible to wear, which in turn produces sound and resonance. When it is confirmed that it is the hum and resonance caused by the tensioner, it is also necessary to check the primer of the car engine, because the role of the primer is to reduce the vibration and sound caused by the car engine. Exhaust pipe deformation:

Generally, the exhaust pipe of the external car engine system is searched for such as the rear tail from the chassis to the rear of the car to widen it. When the road surface is damaged or the chassis of the car is bumpy, it is easy to cause the exhaust pipe to dent and deform. The deformed exhaust pipe increases the frictional resistance of the exhaust pipe, so it causes the exhaust pipe to hum and resonate.

Wheel bearing wear: The wheel bearing is installed in the "horn" of the suspension system, and bears the total weight and impact force of the car all the time in daily driving, among which the rolling bearing steel ball is very easy to wear, and the most common manifestation of rolling bearing wear is the buzz and resonance of the car. Some parts of the vehicle are loose:

For example, fenders or decorative covers for engine hoods. It may be that the vehicle sheet metal is thin, and vibrations and resonance points are generated when the vehicle is moving, creating resonance and humming.

It may be because the sealing strip on the side of the door becomes loose, which will also cause the door to resonate and make abnormal noise, it is recommended to check and replace it; If there is an abnormal sound in the passenger door, it may be the sound of the storage compartment items in the car, the items in the glove box or the sound of the wires of the rear electronic equipment being installed, and it can be fixed. Haval H6 door abnormal noise, generally the door lock block is not adjusted in place, or the lock block is not lubricated in place, resulting in abnormal noise, it is recommended to enter the station for inspection, and then do the treatment If the door lock block is not adjusted in place, you can use a Phillips screwdriver to loosen the lock, adjust some indoors and then lock, you can do it. Several causes and solutions for abnormal door noises:

1. There are small things in the interior panel of the door and bridge tour, such as lighters, coins, etc. 2. The interior trim panel or audio is loose, this fault can be found by shaking by hand, or pressing the abnormal sound when driving, if the abnormal sound disappears, it is a fault here, and it can be re-tightened. 3. The door hinges (hinges) are rusty, this phenomenon will be heard when the door is opened and closed.

4. The door sealing strip is aging, and the door sealing strip will also have this failure if it has not been maintained for a long time, the best way is to buy a bottle of silicone grease to maintain it yourself, apply the silicone grease to the sealing strip, and wipe it off after absorbing for an hour, it will have a good effect. 5. If the door lock block is in poor contact, there is a gap or the lubrication is not good, you can apply butter at the lock block or wrap two circles of waterproof tape around the lock pin. @2019

The reasons for the serious abnormal sound of the right front wheel of Great Wall Haval H6 may be as follows:1. The teeth of the drive wheels are likely to break or have surface damage.

At this point you should pull over and check. If the gear is broken, you should replace it with a new one in time. 2.

It may be an abnormal noise caused by the loosening of the wheel linkage parts. The transmission of the wheels has many gears. If they are too loose, they will make noise when turning.

4.The car is in the running-in period, and the differential planetary gear does not match the half-shaft gear, which requires abnormal noise during the running-in period. 5.

It may be that the poor operation of the human operation leads to the improper coordination of the auto parts in Chiquezhong, resulting in abnormal noise.
