How do I check if my turbocharger is broken?

Judge the turbocharger of a car.

Broken way:

When you step on the accelerator, there is no power charge as before. The engine burns inadequately, and the smell of exhaust is large. The water temperature may not have much of an impact. The rpm increase is slower than before, and there is a strange sound.

1) Rapid acceleration, 1750 rpm or more can hear the scream of the exhaust valve as normal.

2) According to the car kilometer meter, there will be an abnormal sound inside a turbine damage.

3) If the car's turbocharger is broken, the engine warning light will turn on.

4) Unload the exhaust camp at the compressor end to see if there is a large blue smoke from the organic oil exhaust.

5) If the turbine is broken, it will cause the engine to burn inadequately and the exhaust smell will be large. The following methods can also be used to judge the quality of the turbocharger.

Listen: Normal wear is inaudible, unless the foreign body damages the impeller and affects the dynamic balance.

There was a bit of a trembling sound.

Look: Remove the exhaust pipe at the compressor end to see if there is a lot of blue smoke from the organic oil exhaust.

Use: Engine acceleration (more than 1200 approx.) is relatively weak.

Amount: with a pressure gauge.

The measurement is the normal pressure of the inlet pressure.

What are the symptoms of a broken turbocharger.

Blue smoke or white smoke from the exhaust pipe, power decreases, fuel consumption rises, oil consumption increases, turbine pressure is unstable, there is abnormal noise, water temperature is high, engine speed is unstable, and the pressurization effect is not obvious.

1. Blue smoke or white smoke from the exhaust pipe.

2. Decreased power.

3. Fuel consumption rises.

4. Oil consumption increases.

5. The turbine pressure is unstable.

1. Poor sealing of turbocharger impeller shaft.

Fault phenomenon: idling.

When the exhaust gas emits blue smoke, sometimes light and sometimes heavy, there is no blue smoke during driving, and the engine oil is consumed.

Second, the exhaust gas recirculation pipe is seriously blocked.

3. Piston rings, cylinder walls, and valve seals are worn or aged.

Fault phenomenon: the vehicle emits a lot of blue smoke, there is an abnormal sound at the turbocharger turbine end, and the turbocharger turbine end leaks oil.

Fourth, the turbocharger air duct is ruptured.

Can you still drive if the supercharger is broken?

The turbo is still running normally even if the turbo is broken.

The turbo is dual-installed on the exhaust manifold and the intake manifold, so it is safe to say that if the original car with a turbo, no matter how bad it is, it is impossible not to work, the most turbo, the most common problems are turbo delay and oil burning.

If it doesn't work, your car can't vent, in other words, if the car's exhaust is, the turbo must work.

Check whether there is oil leakage, whether the impeller is broken, and at the same time dial the wheel of the supercharger by hand, if the rotation is flexible and the clearance is normal, the general supercharger is no problem. A turbocharger is an air compressor that compresses air to increase air intake. It uses the inertia impulse of the exhaust gas discharged by the engine to push the turbine in the turbine chamber, and the turbine drives the coaxial impeller, and the impeller pressurizes the air sent by the air filter pipe to pressurize it into the cylinder.

When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, the impeller compresses more air into the cylinder, and the pressure and density of the air increase can burn more fuel, and the corresponding increase in fuel volume and adjust the speed of the engine can increase the output power of the engine.

Good morning, big guys, I'm a BYD G6 owner, the car has always had blue smoke recently, and the supercharger has been returned several, and it hasn't been dealt with until now, may I ask you guys to explain what the reason is?

The symptoms of a broken turbocharger are as follows:

1. Decreased power.

2. Increased fuel consumption.

3. Burn engine oil.

4. Blue smoke or black smoke from the exhaust pipe.

5. The engine shakes.

6. Make a screeching sound when accelerating sharply.

A turbocharged engine is an engine that relies on a turbocharger to increase the air intake of the engine, and the turbocharger (turbo) is actually an air compressor. It uses the exhaust gas from the engine as the power to push the turbine in the turbine chamber (located in the exhaust duct), and the turbine drives the coaxial impeller (located in the inlet duct), and the impeller compresses the fresh air sent by the air filter duct and then sends it into the cylinder.

When the engine speed is accelerated, the exhaust gas discharge speed and the turbine speed are also accelerated, the degree of air compression can be increased, and the air intake of the engine will be increased accordingly, and the output power of the engine can be increased.

Benefits: The main function of turbocharging is to increase the air intake of the engine, thereby increasing the power and torque of the engine, and making the car more powerful. When an engine is equipped with a turbocharger, its maximum power can be increased by 40% or more compared to without a turbocharger.

This means that the same engine can be boosted to put out more power.

Take our most common turbocharged engine, for example, after supercharging, the power can reach the level of the engine, but the fuel consumption is not much higher than the engine, on another level is to improve fuel economy and reduce exhaust emissions.

Disadvantages: However, after being supercharged, the pressure and temperature of the engine are greatly increased when working, so the engine life will be shorter than that of the engine with the same displacement without supercharging, and the mechanical properties and lubrication properties will be affected, which also limits the application of turbocharging technology in the engine to a certain extent.

1. When you step on the accelerator, it is not as powerful as before.

2. The combustion of the engine is not sufficient, and the smell of the exhaust is large.

3. The water temperature may not have much effect.

4. The speed increase is slower than before, and there is a strange sound.

Because the turbocharger often works at high speed and high temperature, the temperature of the turbocharger exhaust gas turbine end is about 600, and the supercharger rotor rotates at a high speed of 8000-11000r min, so in order to ensure the normal operation of the supercharger, the following points should be paid attention to in use:

1. Don't leave the car: After the engine starts, especially in winter, it should be allowed to idle for a period of time, so that the lubricating oil can fully lubricate the bearing before the supercharger rotor runs at high speed. Therefore, you must not slam the throttle after starting to prevent damage to the supercharger oil seal.

2. Do not turn off the engine immediately: After the engine runs at high speed for a long time, it cannot be turned off immediately. When the engine is working, a part of the oil is supplied to the turbocharger rotor bearing for lubrication and cooling.

After the sudden shutdown of the running engine, the oil pressure of the engine drops rapidly to zero, the high temperature of the turbocharger turbine part is transmitted to the middle, and the heat in the bearing bearing shell can not be quickly taken away, and at the same time, the supercharger rotor is still rotating at high speed under the action of inertia, so if the engine is suddenly shut down in the hot engine state, it will cause the oil trapped in the turbocharger to overheat and damage the bearing and shaft. In particular, it is necessary to prevent Bi Rolling Spring from suddenly turning off after slamming the throttle a few times.

3. Keep it clean: When disassembling the supercharger, it should be kept clean, and the pipe joints must be blocked with a clean cloth to prevent debris from falling into the supercharger and damaging the rotor. During maintenance, care should be taken not to damage the impeller by collision, and if the impeller needs to be replaced, it should be tested for dynamic balance.

After the reassembly is complete, the blockage should be removed.

4. To be cleaned: because the supercharger is often running at high temperature, its lubricating oil pipeline is subject to high temperature, and the internal oil is prone to partial coking, which will cause insufficient lubrication of the supercharger bearing and damage. Therefore, the lubricating oil line should be cleaned after a period of operation.

5. Pay attention to maintenance: before leaving the car and after receiving the car, the connection of each tube of the airway should be checked to prevent loosening and falling off and causing the failure of the supercharger and the air short circuit into the cylinder.

It can be seen that after the engine is pressurized, the structure of the parts has been strengthened, and from the perspective of use and maintenance, it is necessary to strengthen the mandatory maintenance of the engine and pay attention to the correct control method.

1. Oil leakage, performance phenomenon: large oil consumption, blue smoke or black smoke from the exhaust, and power wax cracking decreases.

Second, there is a metal friction sound, and the performance phenomenon is that there is black smoke from the exhaust, the power drops, and the supercharger has abnormal noise.

3. Bearing damage, performance phenomenon: supercharger bearing damage, engine power decrease, high oil consumption, black smoke, severe supercharger can not work.

There are some ways to determine that the turbocharger is broken: it is not as powerful as before when you press the accelerator, the smell of the exhaust is high, the rev increases slower than before, and there is a strange sound.

If the turbocharger is broken, the sound will be very loud, it is recommended to check the valve of the turbocharger or the engine failure; When you step on the accelerator, you don't feel powerless to dismantle blindly; The engine burns inadequately, and the smell of exhaust is large. The exhaust volume of the car is abnormal.

Turbocharging is to use the inertial impulse of the exhaust gas discharged by the engine to push the turbine in the turbine chamber, and the turbine drives the coaxial impeller, and the impeller compresses and transports the air from the air filter duct to pressurize it into the cylinder. The main function of turbocharging is to increase the air intake of the engine, so that the power and torque of the engine increase, and make the car more powerful. When a turbocharger is installed on an engine, the power can be increased by up to 40% compared to when the supercharger is not installed.

Precautions for using turbocharging:

1. Don't leave in the car.

After the engine is started, especially in winter, it should be allowed to idle for a period of time to allow the oil to fully lubricate the bearings before the supercharger rotor is running at high speed. Therefore, you must not slam the throttle after starting to prevent damage to the supercharger oil seal.

2. Do not turn off the heat immediately.

After a long period of high-speed operation, the engine cannot be turned off immediately. When the engine is working, a part of the oil is supplied to the turbocharger rotor bearing for lubrication and cooling.

3. Keep it clean.

When disassembling the supercharger, it is necessary to keep it clean, and each pipe joint must be blocked with a clean cloth to prevent debris from falling into the supercharger and damaging the rotor.

4. It should be cleaned.

Because the supercharger is often operated at high temperatures, its lubricating oil pipeline is prone to partial coking due to high temperature, which will cause insufficient lubrication of the supercharger bearing and damage. Therefore, the lubricating oil line should be cleaned after a period of operation.

5. Pay attention to maintenance.

Before leaving the car and after collecting the car, the connection of each tube of the airway should be checked to prevent loosening and falling off and causing the failure of the supercharger and the short circuit of air into the cylinder.

When the turbocharger is broken, there will be oil leakage, the impeller may be broken, the rotation of the impeller will be stuck, and the rotation gap will be abnormal.

The turbocharger is an important part of the turbocharged engine, which is actually an air compressor, which mainly uses the exhaust gas to push the turbine of the engine, so as to introduce more fresh air and improve the power of the engine. Today's cars generally use electronic injection systems, and turbochargers are becoming more and more widely used. The exhaust gas turbocharger of the car mostly adopts a single-inlet turbine shell, which only uses the pressure energy of the exhaust gas and has no other auxiliary force.

The turbocharger of the car generally has auxiliary devices, which is convenient for the engine to obtain relatively stable energy within a certain blue speed. The turbocharged engine should also be equipped with a deflagration detection and control mechanism, because the ignition method of gasoline is ignition ignition, and the compression ratio has a certain limit, too high will cause deflagration, and this mechanism can adjust the ignition advance angle at any time.

The most important part of the turbocharger is the bearing, which we can call "full floating bearing" according to the form of lubrication, which works in a harsh environment and works at a very high speed.

If the vehicle has the above symptoms, it is very likely that the turbocharger is broken. Damage to the turbocharger is usually caused by a damage to the oil seal between the turbocharger and the intake pipe, resulting in oil burning. Therefore, it is recommended to choose high-quality engine oil with high temperature resistance and good oxidation resistance, and also pay attention to appropriately shortening the oil replacement cycle to keep the turbine clean.

And although the turbocharger can still be driven if it is broken, it will affect the power performance of the car, and if the turbine burns the oil, it will also damage the ternary, and it will be replaced in time.

Pacific Automobile Network] The performance of the turbocharger is broken: 1. The vehicle power decreases; 2. Insufficient fuel combustion; 3. Serious carbon deposition in the engine; 4. Increased fuel consumption; 5. Burning engine oil; 6. Blue smoke or black smoke from the exhaust pipe; 7. Engine shake; 8. Make a screeching sound when accelerating sharply.

If the turbocharger is broken, the sound will be very loud, because the turbocharger rotor speed has to tens of thousands of revolutions, if you just can't run at high speed, the speed is slow, it is recommended to check the turbocharger valve or engine.

When you step on the throttle, it's not as powerful as before. The engine burns inadequately, and the smell of exhaust is large. The water temperature may not have much of an impact. The rpm increase is slower than before, and there is a strange sound.

The principle of turbine work is to be driven by car exhaust, so the full name of the turbine is the waste turbocharger, which requires the exhaust gas displacement of the engine to reach the value of pushing the turbine to work, so that you can pull the throttle cable by hand on the machine, listen to the sound of the exhaust manifold whether there is any change, the machine reaches the number of revolutions, the turbine will start to work will have a clear suction sound, and if there is a condition, you can cover the air intake with your hand, pull the throttle cable, and see if there is a significant change in the suction volume at different revolutions.

The turbo is installed on the exhaust manifold and the intake manifold, so it is safe to say that if the original car with a turbo, no matter how bad it is, it is impossible not to work, the most turbo, the most common problem is the turbo delay and burning oil, if it does not work, your car will not be able to exhaust, in other words, if the exhaust of the car has, the turbine must work.
