It's okay, it's okay, it's the same with mine, the throttle is pressed down, the sound is stronger than the rev, and there has been no problem for more than two years, and the sound has not been resolved.

The reason for the excessive sound of the car engine "da-da" needs to focus on the following aspects:
1. Many new car owners will suspect that the car engine has abnormal noise when they open the front cover when the car is idling after the first warranty inspection service is returned (because before going to maintenance, they are operating in the cab of the car, and they can't hear the sound of the engine under the front cover when it is normal operational. At present, this sound is heard because in the situation of idling and opening the front cover to find the engine sound, it is natural to hear the sound of the engine operating normally. If you can't hear it in the car, it's not too loud, it's usually the sound of the valve or the fuel injector.
The canister solenoid valve also has this sound, but the sound is brittle. There is a way to distinguish, that is, to give a little oil at idle speed to see if the frequency changes, if the frequency does not change, it is the sound of the solenoid valve, if the frequency changes, it should be abnormal noise at the valve. If you can't hear it clearly in the car, the problem is not big, the vehicle will have a corresponding clicking sound, one is the sound of the fuel injector working, the other is the valve part, and there is a similar sound, which is the sound of the timing chain, but it is different from the clicking sound, there is a Gragra sound.
2. When the general car starts cold, the engine sound will be slightly louder than that of the hot car, as long as the sound sounds uniform and soft, not harsh, there is generally no problem. This is due to the fact that the gap between the cylinder wall and the piston is not yet optimally sized during cold driving, and the lubrication of the oil is not sufficient. Usually when the engine block temperature reaches about 95 degrees, the sound will return to normal.
3. The reason for the oil. Inferior engine oil or not changing the engine oil for a long time, lack of engine oil, etc., can easily lead to increased friction between the valve and the duct and the hydraulic tappet, etc., so that the various sounds in the engine are louder.
4. If you are still not at ease through the above investigation, it is recommended to go to the nearest 4S or auto repair shop to check to confirm the cause of the failure.

The reasons for the sound of BYD's Surui timing chain: 1. The timing chain is lengthened; 2. The timing sprocket is abnormal; 3. The guide chain plate is seriously worn; 4. The chain tensioning device lacks tension.
The reasons for the sound of BYD's Surui timing chain: 1. The timing chain is lengthened; 2. The timing sprocket is abnormal; 3. The guide chain plate is seriously worn; 4. The chain tensioning device lacks tension.
The purpose of aligning the mark on the engine timing chain with the mark of the timing tooth is to fix the crankshaft and camshaft in a certain position. For example: 1gr-fe When the mark on the crankshaft timing tooth is aligned with the timing chain, the piston of the first cylinder of the engine must be in the top dead center position of the cylinder, and when the mark on the camshaft timing tooth is aligned with the mark on the timing chain, the intake and exhaust valves of the first cylinder must be closed.
Timing chain is generally used within 150,000 kilometers is normal, timing chain can be maintenance-free for life, in actual use, timing chain will also produce a certain amount of wear or elongation, generally timing chain elongation will have abnormal noise, so that the tensioner is not very effective, continue to run will be easy to jump teeth, will ignition timing is wrong, high engine fuel consumption, power decline and other problems.
Compared with belts, timing chains also have an impact on engine dynamics. From the consumer's point of view, because the timing belt is mainly replaced by preventive replacement, it is generally replaced when the manufacturer's specified service life is not reached, and the service life is short, the replacement frequency is high, and the follow-up car maintenance cost will increase accordingly. The service life of the timing chain is high, and there is no need for preventive replacement, and only when the chain is used for too long and deforms and produces abnormal noise, it needs to be replaced, so the cost of maintaining the car is also low.

Summary. Hello, I am your exclusive technician, attentive, careful, concentrate on answering your car questions, for you to find the corresponding problem solutions and solutions to the engine to start, generally with this formal chain, this is related to the timing of the chain loose, it will cause the engine to clatter But what about your case, first check whether the engine oil is missing, if the oil is missing, it will also lead to this clattering noise If the oil is missing, I personally suggest adding a little bit on it, I hope it can help you.
Does the clatter of the BYD Surui engine have anything to do with the timing chain?

As soon as the speed of the car comes up, the clutch can feel the obvious vibration.
If the clutch can feel obvious vibration, it is generally the engine foot or the gearbox foot that is damaged, first check the engine chicken foot and the gearbox foot to see if there is this collapse.

Summary. Hello dear! <>
There are three reasons why BYD Surui ignited: 1. The gas is not opened or the valve is blocked. 2. The lighter has weak sparks and insufficient power.
3. The distance between the fire needle and the gas is remote. The reason why Surui does not respond when it starts with a button is that the motor inside the direction lock is stuck, resulting in the induction not being in place and unable to land.
BYD Surui sparked a fire.

Hello dear! <>
First of all, you need to check whether the battery voltage is lower than 10V, the voltage is insufficient, the starting motor voltage is not enough, and the vehicle cannot be moved. The battery voltage is about 12V to drive the starter to work normally, and the power but low voltage cannot drive the starter to run.
The car has electricity, the key can open the door normally, the emergency lights, and the door lights are normal.
Hello dear! Why don't you go and measure the voltage?

Go to the 4S store to test it.
The clicking sound of the idle speed should be produced by the idle valve, it may be that there is too much oil sludge on the idle valve, which affects the adjustment of the stroke, the sound of the solenoid valve afterburner breaking through the restraints, clean the idle valve, wipe some oil on the valve body when restoring, and then wipe it off with paper, don't let the oil be too much. 60,000 kilometers should not have anything to do with cams.
If you feel that the sound of the engine valve is abnormal, it is recommended to go to the pit station to check!
Run the car overhead and take the stethoscope to listen to the gearbox.
Hello, first of all, see if your cylinder has a cylinder misfire, it may be a spark plug breakdown or ignition coil breakdown or open circuit. If it weren't for the above question, how about trying to improve the quality of refueling. It is recommended to go for inspection and repair. I hope it can help you, and I hope to adopt it.
Hello! Regarding your inquiry, this engine noise can cause the following reasons: 1
Wear and tear on the oil pump causes low oil pressure when the engine is idling; 2.The engine oil passage is dirty, resulting in a decrease in oil pressure, an increase in the engine load after the gear, and a valve sound; 3.Wear on the camshaft and valve ejector rod caused the engine to exit at low speeds.

1. The engine has abnormal noise.
Symptom description: There is a lot of abnormal noise in the engine compartment, and most people also judge it to be the abnormal noise of the engine compartment by the sound**, which is usually a metal screeching sound or a howling sound.
Solution: The abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment.
Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.
It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.
2. There is abnormal noise in the gearbox.
Symptom description: If there is a "rustle" sound inside the gearbox while the car is driving, and there is no more after pressing the clutch or accelerator, there will be a whistle-like sound when changing gears.
Solution: There are many transmission parts, and the reasons for the sound are more complex, so we should pay attention to whether it is related to a specific speed, such as some planetary teeth that sound at about 50km h.
Whether it is related to certain gears, which is very important for judging the failure of the transmission, if a certain gear sounds, it must be related to the components that affect the transmission of the gear; If all gears sound, it is often a common meshing shaft failure or a lack of oil in the transmission. Whether it is related to specific actions, such as increasing and decreasing gears, starting, rapid acceleration, sharp deceleration, turning, etc., are effective means to judge abnormal noise, among them, changing speed and direction are particularly important for judging the rear axle fault.
If the abnormal noise of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts, and then replace them.
3. There is abnormal sound of wear.
Symptom description: When driving on the accelerator or brake, there is always some abnormal noise in a certain part of the body, the sound is not loud, and it does not affect normal driving, but it always makes people worry a little about the failure of the body.
Solution: The abnormal noise of the door is mainly caused by the lack of lubrication, but it is necessary to judge whether it is the position of the door hinge or the glass regulator, door lock mechanism, handle mechanism, etc. inside the door. In the case of door hinges or limiters, special door hinges and slide grease can be used, while special door attachment grease is used for lubrication of glass regulators, door locking mechanisms, handle mechanisms, etc. inside the door. In terms of brand selection, try to choose the commonly used brands in 4S stores, such as German Marty, Kluber, Tiger Head Hotolube, Fox, etc.
It is not advisable to use engine oil or ordinary butter, it will freeze in winter, and the harmful smell will affect your health.
On August 11th, I picked up the car Prestige and bought it back for three days, the problems are as follows; >>>More
In fact, this is not absolute, in general: avoid engine idling for a long time, and avoid sudden braking as much as possible. Use the high and low gears reasonably and maintain the appropriate driving speed. >>>More
Hello,These two are relatively niche,If you have to say which of these two is better,Or BAIC Phantom Speed S6It's better。
