General informationTurbokompressor design (on an engine 603.971 example)
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.
Function chart of management of pressurization (engine 603.971)
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 intermediate cooler of the compressed air (interkuler) 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 measuresSpeed 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:
