Questions about the speed and noise of the car s engine gear

You can feel the following for yourself.

To put it simply, in the low-gear gearbox, the small gear drives the large gear to turn the output speed and the torque is small (deceleration and torque), you think about thousands of speeds, the small one drives the big sound must be loud; On the other hand, the big one drives the small old one with ease (the engine speed is lower than when it is in the gear position).

However, you said that the different gears are the same speed, I think what we generally hear is mainly the sound of the engine, and its sound volume mainly depends on the speed of the engine, so the speed is the same, and the sound is the same. It doesn't matter if the old one is in a different gear with the gearbox.

The principle of automatic and manual shifting is the same.

If you make sense, it's a lot of brain-cell work to give me ++ points.

Of course, the sound is loud when the rpm is high in the low gear, but the sound is low in the climbing gear of the big truck. It is more horsepower than a gear. Except for the first gear, it is the loudest to climb the hill. In short, the low-speed gear is more fuel-efficient than the high-speed gear. High horsepower, high revs, loud vibration.

Yes! The engine is louder at low gear and high rpm than at the same rpm in high gear!

To put it simply, the faster the engine revs, the louder it is, and the same goes for automatic transmissions.

The same speed is different in different gears because the gear structure of the gearbox is different, the vibration is different, and the air resistance is different.

The phenomenon of the running-in period There is also the leakage of the exhaust pipe.

Summary. Dear, hello, the second and third gears of the vehicle engine are shaking, and the engine noise is loud, for the following reasons. First, the phenomenon caused by the aging and wear of the relevant clutch pressure plate and clutch plate of the vehicle is completely solved, and the clutch three-piece set needs to be replaced.

The second is the related bearings of the second and third gears inside the vehicle gearbox, or this phenomenon caused by gear wear, which needs to be disassembled and disassembled for inspection. Third, this phenomenon caused by the aging of the engine or gearbox, stationary machine, and claw pad needs to check some fixed chicken feet! If there is a problem, it needs to be replaced.

Dear, I wish you a happy life, if you have any questions, you can continue to consult, I will answer for you as soon as possible.

Hello friends, the relevant information has been sent, you can check it. There may be some network latency.

Summary. While driving, the sound of the transmission and engine will vary depending on factors such as vehicle speed, acceleration, road conditions, etc. But at idle, the engine will be louder than the gearbox.

OK. Hello dear, the sound of the engine is louder than that of the gearbox when idling. At idle, the engine revs at a lower speed, while the transmission stays in low gear or neutral.

Since the gearbox does not carry a large load, the sound it produces is also relatively low. Conversely, the engine needs to provide enough power to the vehicle when idling, so it makes a lot of noise.

While driving, the sound of the transmission and the engine will change depending on factors such as vehicle speed, acceleration, and road conditions. But at idle, the engine will be louder than the gearbox.

Kiss. The gearbox itself can also make noise, especially if there is an abnormal noise when a worker fails. If this happens to your vehicle, you need to overhaul the gearbox and engine of some modified vehicles, and the transmission and engine may also be too loud, which needs to be analyzed and dealt with for the specific vehicle situation.

Is it normal to have a sudden sound of exhaust pipe at idle?

It is normal for the exhaust pipe to have a slight bump when idling, which is usually a sign that the car's engine is running normally.

The reasons for the high acceleration noise of the engine are as follows: 1. The foot vertical bridge glue is aging or loosening: the foot glue is the rubber block between the engine and the frame.

Its function is to reduce the vibration and cushioning of the engine during operation, and to have the effect of fixing the engine. Once these feet are old or loose, the engine will shake, and the faster the speed, the louder the shaking will be. Workaround:

Tighten or replace the rubber on the legs. 2. Improper use of engine oil: if the viscosity of the engine oil is too low, it will cause the lubrication degree to be not empty, enough to wear the engine parts, and produce abnormal noise; If the oil viscosity is too high, the engine will be too negative, and the load will be too large, which will also cause noise.

Solution: Use the oil label on the car manual and do not mix different brands of oil. 3. Engine carbon deposition

When there is too much carbon deposition inside the engine, the ignition energy, air intake efficiency, and mixture ratio of the car will be affected, resulting in unstable power output of the car, and the noise will also enter the cab when the idle speed and acceleration will be shaken. Solution: Go to the 4S shop to carry out the engine cleaning project to remove carbon deposits.

What causes high engine speed and high noise?

The gearbox generally makes very little noise during operation, because there is only a slight jamming sound when changing gears, and after sound insulation, this sound is completely inaudible in the car. The noise of the gearbox is already a big problem if it can be heard. Either the gearbox is damaged, or the gearbox is about to be scrapped.

Due to the continuous combustion, exhaust, compression and other actions of the engine when working, the noise is relatively large, especially when the low gear and high speed, this action is more frequent, and the noise will be greater.

The noise of low gear and high revs must be 90% of the engine.
