1. What is a turbine (turbocharger)?

The turbocharger, also known as car or turbot turbine, represents an aggregate that uses some of the exhaust gases.

The main task of the turbines is to increase the power of an engine. So, with the help of the turbine, you can significantly increase the power of the car. When the engine is in operation, the gases released are directed by a special channel and set in motion a turbine, which in turn compresses the air that enters the combustion chamber. The consequences of this fact are: increase the engine power, on the one hand, preventing the release of gas directly in the atmosphere.

2. Types of turbulent

The operational principle of all turbines is very clear, only that there are differences in the exhaust system. From this point of view, the turbines are divided into four types, respectively:

• Standard – is the simplest, with the most traditional design without escape system;
• Twin Turbo – It is a special type of turbocharger in which two turbines operate in parallel, one small and the other larger. Both are started alternately: the smaller turbine works at lower speeds and the highest high -speed turbine. In this way, the exhaust emissions can be reduced and the engine power can be increased effectively without increasing fuel consumption.
• Variable geometry – This type of turbine is characterized by the design of the internal blades, which reduce the heating of the engine reaction when pressing the accelerator pedal (this phenomenon is called Turbo Lag).
• Wastegate: is a turbine equipped with a pressure adjustment valve. At high speed, the excess exhaust gas is evacuated without turbine.

3. The components of a turbine

The component parts of a turbocharger are:

4. How does the turbine work?

The basic articles of any turbocharger are centrifugal pump is turbine. These are interconnected by a rigid axis. The turbine and pump revolve at the same speed, in the same direction. The energy from the flow of exhaust gas is converted into the couple and then train the unit of the compressor. This happens as follows:

The exhaust gases that leave the engine cylinders are transferred to the turbine rotor, which transforms them into a torque (rotation kinetic energy). The compressor attracts air, passes through the air filter, compresses it and then sends it to the engine cylinders.

In this way the internal combustion engine develops more power.

5. Symptoms of defective turbine

The main symptoms that announce the possibility that the turbine is defective are:

• Decrease in engine power
• When accelerating the car Escape removes blue, black or black smoke
• Consumption suddenly increases
• It can reduce air pressure and oil
• Presence of noise and whistle from the turbine
• The excess pressure pressure is lower
• The smell of burnt oil appears

6. Possible causes for the insufficiency of the turbine

There are many causes that can lead to insufficiency of the turbine. The most common are:

– damaged oil filter

– lower quality oil

– pref and foreign objects that entered the oil

– The valve in the oil filter broke

If you suspect that this could be the cause of your turbine failure, we invite you to read our material on The role and types of engine oils.

• Insufficient lubrication: determines the following problems:

Evering -deserving the turbine during operation, in extreme conditions

Factory defect, contamination or breakage of the oil tube

Defective operation of the oil pump

Defective filling of the new TC lubrication system

Great time of car vectors

• Damage due to foreign objects (dust, misery, metal particles, pebbles and sand).
• The methods of operational limitation accelerate usury TC. The defects of the turbine quickly if it works in extreme conditions:

Defects on the cyber system of the car – the increase in speed above the admitted limit – imbalance;

Game of axis, etc.

Arrest the engine without engines – overheating of the turbine and the formation of soot

Excessive contamination of filters and oil

Mechanical deterioration of the tree, bearings, gaskets, housing.

• The use of inappropriate sealing elements.

7. What happens if you go with the defective turbine?

Why isn’t it good to drive with a defective turbine? Simple:

• Increases fuel consumption (it can grow 2 times, in particular on diesel engines)
• The incomplete combustion of fuel will lead to failure of the catalyst and destruction of the particles filter (for diesel engines)
• A defective turbine leads to the wear of the tree and the sleeve. Under these conditions, oil consumption will increase considerably, significantly influencing the engine.
• There is the risk of carbon deposit on the pistons, which affect the injectors.

Final conclusion:

Although the car can continue to go without a turbine, it is better not to do it. The process involves many risks. The result includes high fuel, maintenance and repairs costs.

8. How is a blocked turbine check?

• Verification of the turbine on the road:

This method does not offer a 100% guarantee that the turbine is defective. But very often the symptoms described below are associated with it.

The turbine is checked on a hot car. You just have to guide him. The car should produce at least the factory characteristics with a more than a few percent error.

For example, if we consider a 2 -liter turbine engine, with a capacity of 200 cp, it should accelerate the wool at 100 km/h in about 7 seconds.

In addition, black exhaust gases can be a sign of energy loss due to the defect of the turbine. This indicates that the valve is clogged or there is a drain in the exhaust tunnel, which does not prevent the turbine from rotating correctly.

The solution would be cleaning the valves or replacement of the turbocharger.

• Verification of the turbine for oil consumption

The car should consume oil in moderation. If the shadow of smoke on the exhaust is blue, it means that the oil is overheated and burns.

• The control of the turbines with the engine started is performed as follows:

You have to start the car

Find the tube between the turbine and the suction gallery – with the help of a friend do this check. Therefore, after finding the pipeline, use and ask the friend to press the adhesion pedal and keep it in this position for 3-4 seconds. Immediately you tell her to suddenly release the pedal. You will feel that the tube begins to swell due to the strong air pressure. Make the maneuver a few times. In the situation in which the tube does not swell, it means that the turbine is defective.

• Visual verification – Make an in -depth inspection of the turbocharger himself. As an idea, there must be no oil stains. Disconnect the tube that connects the turbine and the suction tunnel, make sure there are no traces of oil. It must be absolutely dry. In the case of detection of points or residues of oil it can be assumed that the turbine of the diesel engine is defective or simply «dead».

If everything is fine, he will feel that the pipe swells. Otherwise, problems and diagnoses are needed.

9. The life of a turbine

The average life of a turbine on diesel engines is up to 200,000 km. In the case of engines on the petrol turbine it will take a little more time thanks to its simplest design.

10. What is the ON -Board witness indicating your defect turbine?

In the case of the defective turbine, the «engine control» light signal lights up on the card

Some cars enter the «inert» mode (the speed is limited to 40 km/h).

The diagnosis is displayed by the error code P0299: the turbine or the superimator does not work at the normal pressure level.

See our material about it The meaning of the on -board witnesses.

11. Tips for the maintenance of the turbine

Regardless of the type of turbine in the car, it should be maintained correctly to extend its duration and minimize the risk of damage.

The specialist recommends letting the car started for a moment after driving, so that the turbine has the opportunity to return to the initial temperature (in modern cars there is already such an operation, it is called Turbo time trial).

• Normal changes to the oil are also an important part of the turbine maintenance, they are performed at 10,000 km.
• Timely replacement of the air filter.
• Use of a turbo time trial.
• Oil level monitoring with the help of the joje.
