What's wrong with the abnormal noise of the Buick Enlang engine

1. The reason for the abnormal sound of the Buick Enlang engine is that the oil is too high; the belt is loose; the water temperature is too high; The valve and fuel injector are blocked. Take the Buick Engrand 2021 as an example, its body size is: length 4609mm, width 1798mm, height 1486mm, and a wheelbase of 2640mm.

2. The reason for the abnormal sound of the Buick Enlang engine: When the engine is working, the main sound sources are work explosion, exhaust sound waves, intake resonance, and parts movement. Except for these, it is an abnormal sound. The engine abnormal sound indicates that the technical status of a certain mechanism of the engine has changed.

3. The main reason for the abnormal noise of the engine is: the abnormal noise caused by the aging or loosening of the foot pad. The foot mat is generally installed between the engine and the body, connecting the body and the engine, and plays the role of fixing the engine.

4. It is a cold car valve gap with large and poor lubrication; if there is a sound you described during the acceleration process, it is not a problem with the valve sound; it may be a slight explosion; it may be a slight knock on the cylinder and the ring is stuck; it may be that the cylinder wall has been introduced, and an experienced technician should be checked.

5. The relationship between abnormal noise and engine speed. The existence of most common abnormal noises in the engine depends on the speed state of the engine. 1 Abnormal sounds only exist during idle or low-speed operation.

How to solve the noise of Buick Enlang engine

How to solve the loud noise of Buick Enlang: The main source of Yinglang noise is engine noise, reducing noise The sound method is generally to replace the better oil, use a soundproof intake duct, exhaust and cylinder head to cover with cotton tiles, and the simplest is to soundproof the machine cover.

Change the better car oil.Apply soundproof air inlet. The exhaust pipe and cylinder head are covered with cotton tiles. The alarm cover is soundproof. If the noise is loud during idling and the idling speed of the car is high, the throttle valve, air intake and fuel injector must be cleaned.

Engine noise is mainly transmitted to the cockpit from the firewall and the front bottom plate of the cab. It can be solved by improving the sound insulation effect of the firewall. In addition, replacing the better oil, using a soundproof intake duct, exhaust and cylinder head covered with cotton tiles can reduce engine noise. The simplest thing is to soundproof the cover.

Therefore, when there is an abnormal sound in the engine, it should be repaired in time to prevent the failure from expanding. If it's just that the noise is too loud, noise reduction can be carried out. Generally, the better oil is replaced, the intake duct with sound insulation is used, and the exhaust and cylinder head are covered with cotton tiles. The simplest is to soundproof the cover.

First, confirm whether there is a fault problem with the engine itself. If so, it should be sent to the maintenance agency for repair in time; use the oil suitable for your car engine, and do not use additives indiscriminately; add a soundproof film to the car to achieve the best sound insulation effect and effectively slow down the noise. .

What's wrong with the loud noise of the Buick Enlang engine

1. The whole Buick Enlan uses a three-cylinder engine, and the noise of the three-cylinder engine itself is louder than that of the four-cylinder engine, which is normal. Buick Engrand is a compact car under Buick. This car uses two engines, one is a 0-liter turbocharged engine and the other is a 3-liter turbocharged engine.

2. [Pacific Automobile Network] The reasons for the abnormal noise of the engine of Buick Enlang are: aging or loosening of the foot glue: once these foot glue age or loose, the engine will shake, resulting in abnormal noise. Engine cylinder missing abnormal sound: engine cylinder missing mainly refers to one or more cylinders in the engine that are not working properly.

3. The solution to the loud noise of Buick's new Yinglang engine: the main sound sources are work explosion, exhaust sound waves, intake resonance, and parts friction. Noise reduction can be carried out. Generally, it is better to replace the engine oil, use a soundproof intake duct, exhaust and cylinder head to cover with cotton and tile, and the simplest is to soundproof the machine cover.

4. The reason why the sound of the Buick New England engine is loud: After a period of use, the oil will gradually decline, and it is normal for the sound to become louder at this time;If the engine oil is not suitable, it will also cause the engine to be loud.

What's the matter with the loud noise of the Buick New England engine?

1. In fact, there are many times when there are many reasons why the engine of the car is loud: when the new car first arrives, the freshness and tension of the person will make us less sensitive to the sound.

2. The solution to the loud noise of Buick's new Inlang engine: the main sound sources are work explosion, exhaust sound waves, intake resonance, and parts friction. Noise reduction can be carried out. Generally, it is better to replace the engine oil, use a soundproof intake duct, exhaust and cylinder head to cover with cotton and tile, and the simplest is to soundproof the machine cover.

3. The abnormal sound of Buick's new Yinglang bumps may be due to lack of oil and lubrication in the switch, resulting in dry grinding.And the switch is fixed on the metal bracket to form a resonation, which amplifies the friction sound and causes abnormal sound. This kind of friction will only form at a certain speed if you step on the brakes quickly without making a sound.

4. The buzzing sound at the starting engine pulley of the Yinglang cold car may be caused by the slipping of the belt on the generator. The belt and the pulley vibrate violently, making a certain frequency of noise. The main reason for the belt slippage is the looseness or aging of the belt, among which the factors that cause the looseness of the belt are improper adjustment of the belt tensioner or insufficient elasticity of the tensioner.

5. The whole series of Buick Enlang uses a three-cylinder engine, and the noise of the three-cylinder engine itself is louder than that of the four-cylinder engine, which is normal. Buick Engrand is a compact car under Buick. This car uses two engines, one is a 0-liter turbocharged engine and the other is a 3-liter turbocharged engine.
