2.6.6. Removal and installation of a flowmeter of air

Fig. 2.229. The scheme of installation sites of components of system of injection: 1 – air flowmeter; 2 – a ljambda-probe and heating of a ljambda-probe; 3 – a ljambda-probe after the catalyst and heating of a ljambda-probe 1 after the catalyst; 4 – the gauge of temperature of a cooling liquid; 5 – the valve 1 for the mechanism of change of phases timing; 6 – the valve of a regulator of pressure of fuel; 7 – the one-piston pump of a high pressure; 8 – the gauge of pressure of fuel, low pressure; 9 – the engine заслонки an inlet collector with a potentiometer заслонки an inlet collector; 10 – the gauge of number of turns of the engine; 11 – 6-contact штекерное connection; 12 – 6-contact штекерное connection; 13 – the electromagnetic valve 1 for an absorber with the activated coal; 14 – the block of management of the engine; 15 – the gauge of pressure of pressurisation; 16 – the block of management throttle заслонкой, a drive throttle заслонки (electric management of gas); 17 – the gauge of temperature of soaked up air; 18 – the gauge of pressure of fuel; 19 – the Hall gauge (the gauge of position of a camshaft); 20 – coils of ignition with powerful terminal steps; 21 – перепускной the air valve turbocharger; 22 – the electromagnetic valve of restriction of pressure of pressurisation

Fig. 2.230. The electric tip of a flowmeter of air

Disconnect the electric tip 1 from air flowmeter (fig. 2.230).

Unscrew both screws of an air line on a radiator frame.

Fig. 2.2. An air line

Remove an air line 2 from the case of the air filter (fig. 2.2).

Open a clip of a hose of the air line going to турбонагнетателю, and to pull together a hose from air flowmeter.

Turn off both screws of fastening on air flowmeter.

Cautiously extend a flowmeter of air from directing cases of the air filter.

For trouble-free operation of a flowmeter of air important observe following instructions and an operating procedure.

THE NOTE At strong pollution or saturation by a moisture of a filtering element of the air filter of a part of a dirt or a moisture can get to a flowmeter of air and deform results of measurements of the expense of air. It will lead to capacity loss as calculation of smaller volume of injection of fuel is carried out. Use only an original filtering element of the air filter. For installation of a hose of an air line use greasing (without silicone). For fastening of all connections of hoses use collars of a corresponding series.

Check up a flowmeter of air and an air line hose (the party of pure air) on absence of hydrochloric adjournment, a dirt and leaves.

Check up soaking up channel to a filtering element of the air filter on dirt presence. If the dirt is found out, clear the case of the air filter (the top and bottom parts) of adjournment of salt, a dirt and leaves (if necessary to wash out or clear a vacuum cleaner).

The further installation is carried out in return sequence.
