The help at malfunctions


The turbine турбокомпрессора (2) is put in action by pressure of the following fulfilled gases. The lopastnoe wheel (1) on the party всасывания is set in motion by passing shaft with the big frequency of rotation at the expense of what soaked up air can be condensed. In combustion chambers arrives much more air providing raised capacity or higher twisting moment. As soon as pressure in the chamber всасывания becomes above necessary, the vacuum box of adjustment (3) pressure of pressurisation opens bypass the channel and passes a part of the fulfilled gases by турбокомпрессора in exhaust system. The electromagnetic valve of adjustment of pressure of pressurisation is built in an operating tube (4) for the account of influence of heights on pressure of pressurisation.

The Fulfilled gas.

If Audi Turbo develops considerably lowered capacity or the maximum speed is not reached, the reason can be in faulty турбокомпрессоре.

Before search of malfunctions it is necessary to be convinced that the engine and injection system of serviceability.

The reason
Your help

A.Detali of exhaust and turbo-supercharging system негерметичны

1. The air hose between the compressor and an inlet collector over a radiator наддувочного air негерметичен or was disconnected
2. Негерметичен a site between an inlet collector and a head of the block of cylinders
3. Негерметичны flanges at an inlet collector
4. Not tight site between a final collector and a head of the block of cylinders or турбокомпрессором
V.Neispraven турбокомпрессор 1. Check up pressure of pressurisation. If it too high:
Check up the electromagnetic valve of restriction of pressure of pressurisation, check up a vacuum box of the valve of adjustment of pressure of pressurisation. If that and another in working order, interview a memory of malfunctions in the car
2. Pressure of pressurisation too low:
Check up a vacuum box of restriction of pressure of pressurisation. If it is serviceable, replace турбокомпрессор
