How to deal with the noise of the BAIC Phantom S3 engine?

Cause of failure: This car has a high speed, but because of the low price and poor materials, to ensure that the engine can drive the shell, it is inevitable to make loud noise.

Solution: If you want to reduce noise, change the supergear, but the risk is coexisting, the sound insulation of the whole car is not too big, unless you dismantle the engine to do the sound insulation of the engine compartment, otherwise the effect is not very large.

BAIC Phantom S3 is a 7-seater model independently developed by BAIC Yinxiang Automobile for three and a half years and positioned as a small SUV. As a small SUV, the biggest selling point of the Phantom S3 is the 7-seat design, which is the first of its kind among SUVs of the same price and class.

The product is reasonable, well-configured, competitive, cost-effective, and has obvious advantages over other products at the same level in terms of appearance, interior, space, power, control, configuration and safety, bringing more convenience to consumers and meeting more practical space needs.

BAIC Phantom Speed S3L noise treatment method: do sound insulation of the whole car and replace gears. 1.

Automobile sound insulation refers to the use of special environmentally friendly materials for automobiles, to strengthen the sheet metal structure of automobiles, and to add noise-absorbing materials to ensure that the noise in the car is reduced; 2.Replace the gears, and you can replace one smaller gear to deal with the problem of excessive noise at the high speed of the Phantom S3L. Car sound insulation is a systematic project, each kind of noise will not be independently dispersed from 1 position, taking tire noise as an example, it can be transmitted through the fender, car chassis, rear trunk.

Less than half of the effect of noise reduction in one position is experienced, and the best effect can only be achieved by reducing noise in multiple beats and simple directions for this noise. For example, the chassis of a car is easier to transmit low-frequency noise, and it is easier to hear the friction noise between the wheels and the road surface during the driving process (low-frequency) noise. The effect of sound insulation should be matched according to the material, and the noise reduction effect brought by different materials is different, but at present, some modification shops have noise reduction test equipment, which can facilitate you to have an effect comparison before sound insulation.

For the Phantom Speed S3L, the sound-absorbing cotton of the original car can be thickened, or the whole car can be soundproofed, and Jichun can effectively deal with the noise problem of the car in fast driving.

When BAIC Phantom S3L was first launched, it attracted the attention of the market, setting off a wave of dust and smallness in the compact SUV market, and even felt that it was a "cabbage price" in the compact SUV market. However, recently, a friend responded that the BAIC Phantom S3L is relatively noisy when driving at high speed, so I would like to ask how the BAIC Phantom S3L handles the noise. Now, my brother would like to share with you the experience of a rider.

1. Discover noise problems.

My hostess has been buying it for almost two years and time flies. Because I am a relatively quiet person and have been driving for a long time, I feel that the hostess is a little noisy when driving on the highway, so I think about how to solve this problem.

Second, the process of solving the noise problem.

After a long period of attention, we finally decided to solve the noise problem by replacing the gears. To put it simply, the principle is that the number of gears in 5 gears is a little less than that of the original factory, and the running speed is not the same at the same speed. (For example, the original speed of 100 km/h requires 3000 rpm to run, and after the change, it may only take about 2700 rpm to reach 100 km/h, and the speed has decreased, and the noise is and.)

3. The feeling of use after replacing the gear.

The noise is significantly reduced after the speed is reduced, but the noise is a bit loud when I just switch to running, and it does decrease after the run-in. It used to be around 100-110 per hour. After the change, there is no pressure to run 130-140, and the speed will not be very high.

I am very satisfied with the noise handling of this BAIC Phantom S3L.

The above is my BAIC Phantom Speed S3L noise processing process, which I will share with you here. I hope that friends who have the same troubles as me can solve them through this article. Solve the noise problem, don't increase how comfortable it is when you run, and listen to ** without interference, almost 666.

As soon as the car accelerates, the throttle is slightly stepped on and the buzzing is the problem of oil matching, once the viscosity is too thin oil, it will definitely affect the lubrication and cooling effect of the oil, which will not only affect the power of the vehicle, but also aggravate the wear and tear of the engine. In addition, it may also be because the oil filter element Anhui orange is not in place, when the driver steps on the accelerator to accelerate, there will be a resonance abnormal sound, which can be solved by reinstalling the filter. In addition, if the oil quality of the engine oil is relatively poor and does not have a good lubricating effect, it will also lead to abnormal noise.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions!

Idle speed fluctuations are generally caused by damage to the idle valve. Or it is caused by an air leak in the intake manifold.

1.A leak in the intake manifold will cause the engine oil truck to rpm up and down. Because the throttle is fully closed, and then the air leaks, the economic pressure sensor data will become larger.

If the data is large, the amount of fuel injected will increase. So the computer repeatedly adjusts beautifully. This leads to unstable rotational speed.

2.The intake manifold vacuum tube needs to be inspected and the hose replaced if there is an air leak.

BAIC Phantom S3 idle speed fluctuates high and low.

The throttle valve was changed, there has been no fault code, the intake manifold pressure sensor has also been changed, and there is no air leakage there, and the throttle valve 431 of this car has not been matched.

1 minute after the power is off, it will be automatically reset when it is connected again.

Even if we tried, we were picking up cars that couldn't be repaired by others.

What is the data of the intake pressure, and the air conditioner is not turned on at idle.
