Principle of operation of a turbo engine
The first type of turbines installed on cars is low-boost. High-boost turbines, in turn, have greater efficiency but are quite complex in design. Such engines take into account excess pressure, which greatly harms the engine. To eliminate this problem, manufacturers install a special relief valve on the engine – an actuator.
Like any other mechanism, with prolonged use, the turbine actuator requires periodic maintenance or even replacement. To solve this problem, it is best to contact specialists. For example, on the website of the company "Master Service" on the page https://starter.ms/komplektuyuschie-dlya-turbin-aktuator a wide selection of turbine actuators is presented, which can be purchased at affordable prices.
Also, such mechanisms always come with an intercooler, whose task is to cool the hot air coming through the turbine. It is worth noting that, at equal volume, cold air has a larger volume of oxygen, which positively affects the car's power.
The mechanism contains turbines that spin under the influence of the gas mixture. These blades spin at speeds of over one hundred thousand revolutions. Motor oil is supplied to the shaft on bearings under pressure.
One of the serious disadvantages of this process is excessive fuel consumption. This is because when the engine is turned off, the bearings continue to rotate, consuming fuel. Excess lubrication, in turn, enters the intake manifold and then simply burns in the cylinder. This problem is eliminated by a device such as a turbo timer. The mechanism creates a certain delay before shutdown, allowing the turbine to cool down and not overheat from residual hot gas.
Possible turbine malfunctions
Deformation of the impeller. The problem is mainly associated with foreign objects entering the turbo chamber. In this case, it is best to replace the broken part. It is not recommended to use a turbocharger with a broken impeller, as this leads to complete engine destruction.
Oil supply problems. There are several causes for this malfunction: engine idling, clogging due to excessive sealant application, clog in the oil supply tube. Also, due to contamination, pressure in the chamber may drop.
Deposit formation. It is detected due to high temperatures in the exhaust. The main shaft and bearing are most susceptible to damage. Then the remaining oil channels become blocked, leading to premature failure.
The causes can also be several malfunctions at once: turning off the engine immediately after stopping, poor-quality oil, worn injectors or pump, and other problems in the fuel system.
Algorithm for proper operation
For longer use of the unit, it should be allowed to run for a few minutes. This is done to release excess working pressure in the engine.
Also, when starting to move, you should drive at low power so that the turbine fully warms up. The same procedure must be carried out at the end of movement to avoid a sharp temperature drop.
The car can be turned off after three minutes of final stop. At the same time, be sure to monitor the oil – change it according to the prescribed algorithm, and also consider the quality of the oil itself. There are cases when not very good fluids are used. In this case, the filter is subjected to serious loads and has to be changed much more often. So it is better not to skimp on this product.
