Turbokompressor - the general information, removal and installation


Turbokompressor is intended for increase in engine capacity by a way of increase of pressure of air in the inlet pipeline. Air not simply arrives in cylinders, and moves in them under pressure. According to increase in supply of air, TNVD increases supply of fuel.

The turbine of the compressor is given in rotation by the fulfilled gases. Gases, passing through a special casing (a compressor casing), move to the compressor turbine. The turbine rotates on a shaft on which other end there is a compressor wheel in a separate casing. It submits air under pressure to the pipeline.

Between the compressor and the pipeline the interkuler (address to the Section Interkuler - the general information) is established. In an interkuler air is cooled, being compressed thus. Partsialnoye pressure of oxygen increases that leads to increase in engine capacity.

Pressure of air in the pipeline is limited to the special sensor. At achievement of limiting pressure the sensor opens a zaslonka, limiting to that supply of the fulfilled gases to the turbine.

The shaft of the compressor is greased with impellent oil which moves on specially intended hose. The shaft constantly "floats" in oil. From the compressor oil is taken away in the pallet on a returnable hose.

Turbokompressor is a component of a final collector and cannot be separated from it.

Precautionary measures

Speed of rotation of turbines of the compressor is huge, and the working temperature is very great. To avoid receiving traumas, and also not to damage a turbokompressor, observe the following precautionary measures.

Do not start the engine after removal of any component of a turbokompressor. Hit of extraneous subjects on shovels of turbines can lead to an exit of the last out of operation. You also risk to be traumatized from the subjects thrown out from the turbine.

After removal any a component of a turbokompressor or hoses of an air inlet cover it with pure rags.

Do not give gas at once after engine start, especially if it is not heated-up. Oil cannot instantly grease a turbine shaft.

Never switch off ignition at once after a car stop. Do not press an accelerator pedal before an engine stop. At once after ignition switching off oil ceases to move to a shaft of the compressor and some time it will rotate without greasing.

Before muffling the engine, let's to it work on single turns some minutes during which speed of rotation of the turbine considerably will decrease.

Regularly change oil, the oil filter and an air purifier. Use of old oil will lead to formation of deposits on a shaft of the compressor and to its exit out of operation. Before disconnecting hoses of giving and oil return from the compressor, carefully clear nearby surfaces. The removed components store in tight containers.
