Fig. 202. The air filter and the details located near to it: 1 — the top part of the air filter; 2 — a vacuum hose; 3 — an O-shaped sealing ring; 4 — the gauge of the mass expense of air; 5 — штекерная колодка for the gauge of the mass expense of air, black colour; 6 — a hose of let in air; 7 — штекерная колодка, black colour; 8 — a heating element of system of ventilation картера; 9 — a connecting hose; 10 — the valve of system of ventilation картера; 11 — a ventilating hose; 12 — a collar for (13); 13 — the electromagnetic valve of system of clearing by means of the activated coal; 14 — a ventilating hose; 15 — штекерная колодка, green colour for (13); 16 — rubber муфта; 17 — a filtering element; 18 — the bottom part of the air filter; 19 — an air inlet hose

The gauge 4 (fig. 202) the mass expense of air термоанемометрического type, is located between the air filter 1 and a hose 6 inlet pipes.

Sensitive element of the gauge of the mass expense of air is the small metal plate which heats up in the electric way. The stream of air soaked up in the engine passing by the gauge cools a metal plate, thereby reducing its electric resistance which measures the gauge. The more the volume of soaked up air, the accordingly is more strongly cooled this plate. ЭБУ will transform the received sizes to signals for system смесеобразования.
