As soon as the turbocharged engine of the car releases the throttle, I hear the sound of gassing?

Hello, according to your description, the sound made here should be from the turbo pressure relief valve It is recommended to go to the local dealer or maintenance station to find the same level of car series for comparison, if it is abnormal, it is recommended to find a professional maintenance personnel to check the specific problem, I hope to help you.

If it's a turbocharged engine, then it's the sound of the turbocharger working, and if it's a naturally aspirated engine, it's probably a leak somewhere in the intake pipe. If such a situation occurs, it is necessary to detect whether it is a ** air leak before repairing it.

Question: What is the reason why the engine hears a deflation sound as soon as I step on the accelerator?

Answer: Come on, do you need to deal with it, do you need to deal with it. Leaking air in the intake system, large valve gaps, dirty transmission oil, and aging belts can all make refueling audible. Air intake leakage is the most common failure, when there is a crack in the vehicle's air intake system, the high-velocity airflow will be discharged from the gap, which will lead to a sizzling or whistling sound.

If the intake pipe is seriously damaged, it will also greatly affect the power output of the vehicle, and will also cause an increase in fuel consumption. Therefore, when there is a sizzling noise, it is best to go to the repair shop as soon as possible to check whether there is any air leak in the intake manifold. Stepping on the accelerator has a leak-like sound, and this problem is mainly caused by two reasons.

One is that the intake manifold is broken and leaking, and the other is that the valve gap is too large or the valve is loose. Nowadays, many of the intake pipes of vehicles are made of engineering plastics, and due to the high temperature in the cabin, plastics are prone to aging, so the intake pipes of older cars are prone to air leakage. The valve will work according to the degree of opening and closing of the throttle, as a part that needs to be moved frequently, the valve gap will become larger after the valve is worn, so that the owner will produce an air leak sound when pressing the accelerator.

"There are two reasons for this:1Leakage of the starter;2.

There is a problem with the car's air supply and exhaust system. Car inspection method: If there is no problem with the intake and exhaust system, start the vehicle, pull out the oil dipstick, and check whether there is still sound.

If there is, there is a problem with the oil seal;Also open the lid of the water tank and top it up. If there are bubbles coming out, it can be concluded that there is an air leak into the tank. Finally take out the air to worry if there is a sound.

If there is a problem with the intake valve or exhaust valve, if the air cleaner is tempered, it is the intake valve, and the exhaust pipe discharge is the exhaust valve.

As soon as the engine stepped on the accelerator, you could hear the sound of deflation, what happened? Is this false, does this need to be checked carefully, it is estimated that which oil seal has been broken and damaged?

It is the sound of the pressure relief valve working, and the turbine compresses a large amount of air through the throttle to the engine combustion chamber when the accelerator valve starts working, but when the driver releases the accelerator pedal, the throttle closes.

However, the turbine blades do not stop working immediately, and there is still residual compressed air in the intake duct between the turbine and the throttle valve, and if this air is not discharged in time, the strong pressure will cause damage to the throttle and turbine blades.

Scientific principle: turbocharging device is actually a kind of air compressor, through the compression of air to increase the air intake of the engine, in general, turbocharging is the use of the engine exhaust gas inertia impulse to push the turbine in the turbine room, the turbine drives the coaxial impeller, the impeller pressurizes the air sent by the air filter pipeline, so that it is pressurized into the cylinder.

It's not a bleed valve, it's a sound from the exhaust pipe, a turbo pressure relief valve, and the sound is kind of like a whistle, or it's just a flutter, and you can release the throttle.

Relief valve: supercharger, that is, the engine intake supercharger, the air before entering the engine cylinder is compressed by the supercharger to improve the density of the air, so that more air is filled into the cylinder, thereby increasing the engine power. In addition to the high take-off power output of the supercharger, the supercharger-equipped engine can also improve the altitude characteristics of the engine.

Summary. Hello, dear, car master exclusive technician for your service, attentive, careful, concentrate on answering your car questions, for you to find the corresponding problem solutions and solutions, will provide you with a satisfactory answer! We hope you find this service helpful.

The reason why turbocharger has a deflated sound when we retract the throttle normally is because there is a solenoid valve on the turbocharger, codenamed N249 The sound of the solenoid valve working, its function is to remove the pressure between the turbocharger and the intake pipe to prevent the burst, and there is also a turbocharger solenoid valve next to it, one is to work with the throttle, and the other is to work with the throttle.

What's the deal with the "deflating sound" of a turbocharged engine when it slackens oil?

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!
