1. The reason for the abnormal sound of cold car start is generally caused by the loss of lubrication of the internal gear of the starter, the occurrence of astringency and jamming, which affects the timely return of the gear. That is, when the engine is started, the starter rotates to drive the flywheel to rotate, so that the engine starts, and the speed of the engine is driven by the starter, so the engine speed is lower than the starter speed, when the engine starts and the speed is higher than the starter speed, the manual operation ignition switch is powered off and the starter is closed.
Second, because the inside of the starter is too dirty, the lubricating oil fails, and the starter is forced to drive the starter to run by its own speed through the flywheel engine.
3. When the starter is in a hot state with the engine, this sound will end, but there will be a sound every time it is started. To get rid of this sound, you can only clean and maintain the starter or replace the starter, but the effect of cleaning and maintenance will not be very good, and it won't take long to ring again, so if you can tolerate this sound, you still don't change it, and wait until it is broken and completely solved.

A cause that cannot be underestimated is "carbon deposition", which will cause insufficient combustion of gasoline, so that the engine will have the problem of shaking and abnormal noise. The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless. The second is to increase fuel consumption and increase your financial burden.
The third is the difficulty of cold start, that is, the difficulty of ignition, it is not easy to get on the car, and finally the serious carbon deposition in the combustion chamber will also cause cylinder detonation, and there will be a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, thereby seriously affecting the safety of the car. Then there is the excessive discharge, which not only fails the annual inspection and inspection, but also directly aggravates the harm of polluting the environment.
There is another reason: the throttle valve is faulty. Both of these problems can cause engine shake and unstable revs (German Marty, professional technicians can solve problems for you).

Summary. This sound occurs in the case of the engine at idle, this is a normal phenomenon in the case of idling, the speed ratio of the engine is relatively low, the timing chain of the engine, including the valve of the engine, including the fuel injector of the engine, will make this sound when the speed is relatively low when working, this is a normal phenomenon now. This sound will appear in every engine idle situation, which has no effect and can be used normally.
The Refine S3 engine clatters.
Dear, this question is up to me, it takes a little time to type, please be patient, thank you!
This sound occurs in the case of the engine at idle, this is a normal phenomenon in the case of idling, the speed ratio of the engine is relatively low, the timing chain of the engine, including the valve of the engine, including the fuel injector of the engine, will make this sound when the speed is relatively low when working, this is a normal phenomenon now. This sound will appear in every engine idle situation, which has no effect and can be used normally.
There is a clattering sound clearly outside the car, but it is obvious in the car, and the sound is still very loud, whether it is a cold car or a hot car, the sound of the hot car is even louder.
How many kilometers has that car run now?
Ten thousand. This phenomenon is normal, this engine is originally a little louder. This has no effect, and it will work fine if you use it normally.
How much does this sound appear in 1 year, this situation is mainly to put it bluntly, or the quality of this engine is very general and the number of kilometers used is relatively small, it appears this sound, which means that there is slight wear and tear in the engine, and the gap is too large.
It's very disturbing to listen to, is there a way to govern it.
What type of oil is you using now?
5w30.
It is recommended to change the oil of 5w-40 to try it, and increase the viscosity of this oil slightly.
Ok thanks.
You are welcome. If I can help you, please give me a thumbs up Thank you!

The front wheels of the vehicle make abnormal noises, know what may be the causes of abnormal noises, and check and repair the vehicles accordingly.
Possible causes of abnormal noises 1Front shock absorber failure 2Front-wheel drive half-shaft loose 3
The chassis screws and rubber components are loose, and the ball joints and bearings are loose Inspection steps: Lift the vehicle with a lifter. Check the screws and rubber components at the front end of the shiny chassis for loose skins.
Remove the front shock absorber and check if the shock absorber is good.
In terms of power pure leather, the mass-produced Ruifeng S3 is equipped with an engine with a rated power of 83kW 6000rpm; The maximum torque is 146 Nm, and the low-end torque is 100 Nm. In terms of transmission, the engine is matched with 6MT and CVT gearboxes, and the fuel consumption will be reduced to 100 kilometers, which also reduces the cost of using the car.
Compared with the old model, the combination of the VVT engine and the high-ratio gearbox has improved the dynamics to a certain extent.
The Refine S3 adopts a VVT engine with a torque of up to 155Nm, coupled with a large speed ratio transmission and a lightweight body design, so that the vehicle has good climbing and starting acceleration performance, so that you can start "one step faster"; At the same time, it has a better high-speed overtaking ability than similar models, so that you can drive at high speed.
Technological development:
With the development of science and technology, more and more high-quality cars have been developed.

The abnormal sound of the engine clattering should be alone or one or two of this abnormal sound, first check whether there is a problem with the valve top, you need to disassemble the valve chamber cover for each valve top to detect, and if it can be pressed, it means that there is a problem. In the case of the upper cover of the engine, it needs to be checked and there is pressure. This is caused by the lack of oil pressure.
The car master is here to help.
The Refine S3 engine clatters.
Hello, happy to answer your questions.
Hello mine is 16 years JAC Ruifeng S3 when the sound is normal when the car is hot, the sound is louder than the diesel engine, I changed a timing chain half a year ago, may I ask what the problem is.
Hello. I am your exclusive technician, attentive, careful, attentive to answer your questions, I hope this service can help you. The abnormal sound of the engine clattering should be alone or one or two of this abnormal sound, first check whether there is a problem with the valve top, you need to disassemble the valve chamber cover for each valve top to detect, and if it can be pressed, it means that there is a problem.
In the case of the upper cover of the engine, it needs to be checked and there is pressure. This is caused by the lack of oil pressure. Check whether the lost pump is worn out, and whether the gap between the pump and the tile is too large.
Hello mine is 16 years JAC Ruifeng S3 when the sound is normal when the car is hot, the sound is louder than the diesel engine, I changed a timing chain half a year ago, may I ask what the problem is.
Then you need to check whether there is a problem with the communicative period of the chain, as well as the variable wheel.
Hello, can you tell us more about it? Thank you.
You also need to check whether the tensioner of the tensioner timing chain is caused by pressure relief and variable wheels? This can happen as a result of pressure relief.
At that time, when the chain was changed, the cylinder head was also taken to someone to grind the valve, and when there was an abnormal noise, check the two I said.
When the car is hot, it is louder than that of a diesel engine.
In this case, it is very likely that the oil is not on the inspection and the oil passage is blocked.
When the cold car starts, it is normal, and then when the car is warm, it is very loud and loud.
Yes, the points I mentioned are specifically checked.

1.There are two corresponding inspection methods: hit the steering wheel to check for abnormal noises.
There is an abnormal noise when the brakes are applied. When the steering wheel is turned, the chassis makes an abnormal noise. Check whether the outer cage of the vehicle is damaged or whether the tie rod ball head is moving too much.
When the brake chassis makes an abnormal noise, check whether the brake pads and brake discs are seriously worn. When the ball joint of the lower swing arm is damaged, it will also cause abnormal brake noise and shaking.
2.The abnormal sound of Ruifeng S3's bumpy road may be due to loose screws of some parts, or aging and damage to the rubber bracket. Typically, the bracket pads of the engine and transmission are more damaged.
If these conditions cause the vehicle to make abnormal noises, simply tighten the screws and replace the aging or damaged rubber bracket pads, and the problem will be basically solved. The function of automobile shock absorber is to accelerate and attenuate the vibration of the body, realize the function of cushioning and shock absorption, and is an important component that determines driving comfort. If there is still a strong bump after tightening the screws, you need to check the shock absorber to guarantee the safety and comfort of the vehicle.

Causes and treatment methods of abnormal noise of Ruifeng S3 second-generation gearbox:
1. When the engine wheel belt is idling, Xiaofeng makes a rhythmic sound of "rattle, rattle, rattle", and the sound is more serious when the throttle is increased, and the transmission is vibrated phenomenon, which is generally caused by the tooth surface peeling off or the tooth fracture and tooth loss, if the repair and assembly are misaligned, the gear center is offset, and this sound will also be emitted.
2. There is a rhythmic and dull sound in a gear during driving, and the sound disappears when you hold the gear lever with your hand, which may be caused by the wear of the gear fork concave wax rising reed groove or the wear of the working face at the lower end of the gear lever, which should be dismantled, repaired or replaced;
3. The sound is obvious after changing into a gear during driving, that is, the gear is worn out too much and the sound is sounded, and if it makes a periodic sound, it is the damage of individual gear teeth. If there is a sudden impact sound during the shifting operation, it may be a broken wheel tooth, and the transmission should be disassembled in time for inspection and repaired or replaced.
Some engine noises change with the condition of the vehicle, but the most noise comes from the engine's lubrication system. Mainly due to the nature of the oil and abnormal maintenance >>>More
The oil is not good, if you use No. 93 now, add No. 97 to try, the clicking sound may be a knock on the cylinder, but the knock on the cylinder will only be when you step on the accelerator to accelerate, and the throttle will be gone, and the valve will have a clicking sound, you try it first and then say, don't open the cylinder if you have nothing to do, and hurt the car.
The blue smoke from the engine is basically burning the engine oil, and there are many reasons for this, roughly the following situations: >>>More
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. >>>More
In the current car market, if you want to find a model is not very difficult, but 80,000 yuan can buy a standard car networking CVT model is rare, and if you can buy a comparable or even more than three or four hundred thousand yuan of the same level of power joint venture brand SUV, it is even more value-for-money. The Refine S4 engine has a maximum output of 150 hp and a maximum torque of 210 Nm. The same hot-selling car, Volvo XC40 has a maximum horsepower of only 140 horsepower, and BMW X1 has only 136 horsepower, which are all foreign brands in the price range of 10,000 yuan. >>>More
