The engine sound is not the best

The engine sound is not the best Don't be in a hurry to change the parts, clean the oil circuit first, which has dealt with a lot of links before. Car repair is all about testing by elimination and achieving maximum improvement at the lowest cost. If your car has not been used for a long time, effective cleaning results, it is recommended to clean it first, because the problem of misfire and lack of cylinder caused by poor fuel combustion abounds.

If the oil is really dirty and you change the accessories, it will still be a fire in the future. Directly use the Si Youpu fuel cleaning agent refueling tank, run 3 tanks of oil, most of the misfire and lack of cylinders as long as it is not a problem with accessories will be smooth.

Many car owners complain that the noise of their cars is getting louder and louder, what is the reason?

If the engine is noisy and does not last long during a cold start, there is generally no problem, but when the engine starts for a while, the engine will return to normal and there will be no more violent noise. In addition, engine oil, belt tightness, etc. will cause high engine noise.

If my engine is loud, it may be a little longer in use, and I can consider replacing it with a new one.

Are you buying a new car? Or is it a used car? If the car's engine is too loud, you can go to a 4S shop and have a look.

It is possible to add sound insulation and change the high-quality engine oil. It's a lot better. The sound insulation should be done well. Very important.

Generally speaking, generators are loud, but if there are too many generators, you still have to go for repairs.

The engine is loud, whether there is loosening of fasteners, you need to ask professionals to find the problem, and deal with it reasonably.

If the car engine is very loud, it may be caused by not changing the oil for a long time, or it may be caused by the wrong viscosity of the selected oil.

Engine oil is known as the blood of the engine, and it plays the role of lubrication, cleaning, heat dissipation, and sealing in the engine.

If there is a lack of oil in the engine, the engine will not work properly.

When the engine is working, the oil will form an oil film on the surface of the various parts of the engine, so that the friction of the various parts of the engine will be reduced. If the oil is used for a long time, the oil will become thinner, so that the engine will become louder when it accelerates.

If the viscosity of the oil is not right, the engine will also be noisy.

If it's loud, it's possible that there is something wrong with your oil. It is recommended to try it differently.

The following is how to deal with the high noise of the engine:

1.If the engine belt is loose, you need to go to the 4S shop to replace the belt.

2.If there is carbon deposit in the engine, the repair shop needs to remove the carbon deposit.

3.The sound insulation effect of the vehicle is poor, and the sealing strip of the vehicle should be checked for old traces, and if it is aging, it needs to be replaced.

A normal car engine should be without a screeching sound during the start of the engine, and the engine idle sound is even. There may be a clicking sound when the cool car starts, and the sound weakens and disappears after the engine warms up, which is a normal engine sound. Here's why your car's engine is louder:

1. The engine has a kicking sound, like the sound of a pencil hitting the table. The possible cause is that there is dirt inside the engine, it is recommended to change the oil engine and filter the engine; 2. When the acceleration is normal during driving, the ignition is normal, but when driving at a constant speed, it is found that the engine speed is too high, but the speed still does not seem to be able to rise. Try checking the coolant, and it is also possible that there is a problem with the ignition time setting that can also cause these symptoms; 3. The engine makes a clicking sound when idling, as if something is hitting the metal.

It may be that the cylinder valve can be changed by adjusting the valve; 4. When the engine is accelerating, there will be a whirring sound or deceleration. The possible reason is that the power steering oil is missing, and the generator bearing may be damaged. Problems with power steering pumps and water pumps will produce similar noises; 5. When you step on the accelerator pedal, you will hear a banging sound coming out of the exhaust pipe, and the sound may not be very loud, and the car will not be abnormal when driving, and the fuel consumption will increase.

It is advisable to check whether the muffler and exhaust pipe are damaged.

The reasons for the loud engine are as follows:

1. Poor oil quality, if you use poor quality fuel, the combustion situation in the engine will become worse, so that the engine will vibrate violently and make noise quickly. Solution: In this case, generally replacing the better quality fuel can reduce the engine noise.

2. The engine is fixed and loose, you should know that the engine is not simply placed in the engine compartment, but supported and fixed by claw pads and other components, if those parts are aging and loose, it will cause the engine to produce noise when working. Solution: In this case, it is necessary to check the engine support and fixing parts, and generally tighten or adjust it.

3. The engine is noisy during cold start, and when the car is parked for a long time and starts, the engine will vibrate violently, and then make a "da-da" noise. This is because after the car is parked for a long time, the lubricating oil basically flows to the oil pan, and the oil pump can not immediately establish the oil pressure when the cold car starts, especially the valve inside the cylinder head, which is not sufficiently lubricated when the cold car starts, and the hydraulic tappet and the mechanical rocker arm fail to work normally to cause the sound.

Basic maintenance items for automobile engines

1. Regularly change the engine oil: the engine oil is the lubricant of the engine, which can lubricate, clean, cool, seal, reduce wear and other functions of the engine, and is also the "blood" of the engine.

2. Replace the three filters regularly: The three filters refer to the air filter, oil filter and gasoline filter. The three filters can provide the engine with the effect of filtering impurities, protect the engine, and also improve the working efficiency of the engine.

The regular maintenance interval of the three filters is the same as that of the engine oil.

3. Power steering fluid: Power steering fluid is commonly known as direction oil, and it is necessary to regularly check whether there is any leakage or obvious abnormal noise. The electronically assisted models are maintenance-free, and there is no need to change the direction oil. The maintenance interval of directional oil is about 60,000 kilometers.

Hello dear, <>

I am glad to answer for you, how to solve the problem of loud engine in the face of such a situation, you only need to change the oil. The engine is noisy when the car is parked for a long time and then starts, the engine will vibrate violently and then make a "click" noise. Because after the car is parked for a long time, the lubricating oil basically flows to the oil pan, and the oil pump can not immediately establish the oil pressure when the cold car starts, especially the valve inside the cylinder head, which cannot be lubricated enough when the cold car starts, and the hydraulic tappet and the mechanical shaking arm fail to work normally to cause a clattering sound.

At this time, the noise is normal, and when the engine starts for a while, the engine will return to normal and there will be no more violent noise. 2. How to solve the problem of engine noise caused by the wrong engine oil condition, oil is an important component of engine lubrication, and when there is a problem with the engine oil, it will affect the working condition of the engine. When the viscosity of the engine oil is too high, it is easy to cause problems in the operation of the engine, and the lubrication effect becomes poor, resulting in friction during the operation of the engine, resulting in noise and sound.

All you need to do is change the oil. <>

1.During the start of the engine, there should be no squealing sound in the starting motor; The engine idle speed "sudden sound" is uniform, and there is no abnormal noise; The idle speed is stable at about 850 rpm (please refer to the car manual for the specific stable idle value). 2.

Gently step on the accelerator, let the engine speed slowly increase, there should be no noise in the process, individual models will have resonance phenomenon at a fixed speed, that is, the whole body shakes (if the resonance is very slight, does not cause riding discomfort, it should be normal), after the speed resonance phenomenon should be eliminated; When the engine speed exceeds the maximum power point speed, the sound is generally more noticeable, but there should be no metal friction sound. 3.Press the accelerator pedal quickly, and the sound of the engine power increase should be smooth and free of lag; Carefully distinguish the sound of each engine speed.

The main noise is: valve sound (generally "clicking" sound), if it is large, there is a suspicion of top valve; All kinds of belt rotation sounds (generally "squeak" sounds), if large, may be the belt and the body friction; If the engine emits other friction sounds, it is doubtful that the sudden sound is masked. 4.

Find a suitable place, drive the vehicle according to the compound road conditions for 5-10 minutes, and the idle speed should still be stable at the original idle speed without change after stopping, and the sound should be the same as before. 5.Open the bonnet, listen to the sound on both sides of the engine, and at the same time move the accelerator control raft with your hands, and listen carefully to the engine sound according to the key points mentioned above.

How to judge the quality of an engine by its sound:

1. In the process of starting the engine, the idle sound is uniform, no abnormal noise is good, and there is a screaming sound when starting is bad;

2. Gently step on the accelerator, let the engine speed slowly increase, there should be no noise in the process, individual models will have resonance phenomenon at a fixed speed, that is, the body will shake, if the resonance is very slight, does not cause discomfort in the ride, it should be normal, and the sound will be eliminated after the speed resonance phenomenon;

3. Quickly press the accelerator pedal, the sound of the engine power improvement should be smooth and no lag is good, and the sound of each speed of the engine should be carefully distinguished.
