GENERAL INFORMATION

Power supply system air

The air arriving in the engine, is cleared by the air filter and, mixing up with fuel, forms the fuel mix which is burning down in cylinders of the engine.

The power supply system air consists of the following knots:

      – air filter;
      – resonant chamber;
      – sensor of a measuring instrument of a consumption of air;
      – throttle knot;
      – inlet collector;
      – valve of a control system of frequency of rotation of idling.

The sensor of a measuring instrument of a consumption of air measures amount of air arriving in the engine and transmits a signal to the control unit.
The resonant chamber suppresses the noise caused by a pulsation of air.

The throttle knot includes:

      – sensor of provision of a butterfly valve;
      – valve of a control system of frequency of rotation of idling.

The system of idling provides to giving of a small amount of air bypassing throttle knot for ensuring frequency of rotation of idling.

System of production of the fulfilled gases

The fulfilled gases contain mainly nitrogen (N2), and also carbon monoxide (WITH), carbon dioxide (CO2), water vapor (H2O), oxygen (О2), nitrogen (NOX) oxides, hydrogen (Н2) and various nedozhzhenny hydrocarbons (NANOSECOND). Rub from these components – WITH, NOX and NANOSECOND are the most serious pollutants of air therefore their emissions in the atmosphere should cope.

The catalytic converter established in system of production of fulfilled gases, works as the gas reactor for reduction of level of the polluting substances released into the atmosphere. All internal volume of the case is filled with the ceramic porous monolith, representing the ordinary filter, the internal and external which surface of a time contacting to gases, is covered with very thin molecular layer of an alloy from the active catalytic substance containing platinum, rhodium and a palladium.

In catalytic converter there is a reaction as a result of which dangerous hydrocarbon and a carbon oxide in the fulfilled gases turn into safe gases and water vapor.

Power supply system elements air

 
1–zabornik of fresh air;
2–inlet air branch pipe;
3–case of the air filter;
4–measuring instrument of a consumption of air;
5–the resonant chamber (only on the TED engine
Removal

PERFORMANCE ORDER
1. Remove power supply system elements air in the sequence designated by figures on fig. Power supply system elements air.
2. Visually check a condition of elements of a power supply system air and, if necessary, restore or replace them.

Installation

Installation is made in sequence, return to removal.
