How to check the turbine?

Manufacturers of cars, in order toIncrease the power of the motor equip the engine with special turbines, working as a turbocharger or turbocharger. The failure of this device makes discomfort the further operation of the car and leads to a decrease in its dynamics. In this article, let's look at how to test the turbine.

Symptoms of a malfunction

The loss of engine power of the car, with the same fuel and oil consumption
When dispersing, there is a burst of blue or black smoke from the exhaust pipe
Extraneous whistle and noise when the engine is running
Increased oil consumption and oily stains near the turbine

In the service center, a malfunction of this unitusually detected using a special electronic scanner and a pressure gauge, which are attached to the desired connector of the car. After starting the motor, these instruments give out data on the functioning of the entire motor system. However, you can check some points yourself.

Self-test turbine

Disassembling how to check the turbine, first thingit is necessary to inspect the pipe, which is connected to another, which supplies air to the turbocharger. Having disconnected it it is necessary to check the turbine blades. They should be smooth, with the correct form. Any notches, curvatures and nicks must alert you, as this requires repairing the turbocharger or replacing it with a new one.
Next, you should inspect the pipe itself. Be aware that only slight oil swelling is allowed, which means that it should be practically dry. If there is a lot of oil inside the nozzle or at the inlet to the turbocharger, this is a certificate of engine wear or a turbocharger malfunction. In this case, more thorough diagnosis by specialists is required.
Also, turbocharging malfunction is determinedmoving it in the axial direction. The tolerance of backlash is 0.05mm. A pronounced axial play shows the need to repair the turbocharger or replace it completely. In the radial direction, the backlash norm is 1mm.
The next step is to determine whether thescapula for the cochlea. To do this, move the shaft in the radial direction and rotate the blades. If they hit a cold snail, this indicates a malfunction of the turbocharger.
Next, inspect the connection between the intake manifold and the sensor tube. Violation of the geometrical connection can lead to the failure of the turbine. In the presence of cracks and abrasions, it must be replaced.
Considering how to test the turbine on a diesel engine,it is necessary to forget about inspection of aperture in an inlet collector. Its diameter is only 1 mm, and its clogging leads to the shutdown of the turbine. In this case, it is necessary to clean this hole.
Traces of antifreeze are a sure sign of poor-quality connection of cooling tubes.
If all of the above actions did not helpyou will find out the turbine malfunction, and the engine power still falls, then it remains to check the tightness of the inlet and exhaust tract or contact specialists who, with the help of special equipment, will accurately diagnose both diesel engines and gasoline engines.
