Electropneumatic system we supply control

Electropneumatic system we supply control ¬ ¬ excited spirit (4A-FE (AE101 and A190))
Note: This valve can be designed to:
- Office of the bypass air zadrosselnoe space, E-nuya throttle (to reduce the dilution modes overrun)
- Inclusion of the executive mechanisms of controlling the turn in extra-Drosia selnymi flaps ("bypass-governmental" or "eddy" flap-mi) installed in the inlet nozzles individual cylinder just before the inlet valves, ¬ E (¬ system to measure the geometry nyaemoy Intakemanifold system for engines with lean burn ¬ subject ¬ to this mixing.)
Circuit of the valve. 1 - elec ¬ ¬ tropnevmoklapan management system leniya air supply, 2 - to heads of Nome ¬ relay injection top Lib ¬ 3 - ¬ electronic control unit leniya.
1. Remove the valve.
2. Check valve.
a) Using an ohmmeter, connect to terminals chennogo connector valve-on, make sure that no open-circuit coil valve, measuring the ve ¬ disguise its electrical resistance ¬ tance.
The value of winding resistance valve (cold) co-seems. 33 - 39 ohms
If the resistance was above normal, replace the valve, b) Using an ohmmeter, a pro ¬ water which in turn is obtained ¬ connected to the conclusions of the valve plug, and another - to the valve body, convincing ¬ Tes in the absence of the winding circuit ¬ ki valve mass.
If the ohmmeter registers any resistance other than the infinite infinity ¬, then replace the valve. 3. Check the operation of the valve.
a) Make sure that the air passes through the orifice "E" to the opening of "0".
If conditions are not met for menite-valve. 3. Install the valve into place.
Oxygen sensor (models with a catalytic converter otrabo tavshih-gas)
To reduce the content of otrabo-tavshih gas vehicle components Comrade CO, HF, NOx using three-component catalytic her-centralizer. But for the most effec ¬ tive to the use of fuel-air ratio is constant should be close to stoichiometric.
The output voltage of the oxygen sensor varies depending on the composition of the fuel-air mixture in order to control of the content of oxygen in the exhaust gases and provide feedback to the electronic control unit to control the composition of the fuel-air mixture.
The design of the oxygen sensor ¬ ka. 1 - sensor body, 2 - vy ¬ platinum electrode, 3 - solid elec ¬ trolley (zirconia element), 4 - platinum electrode, 5 - ceramic coating nomic, 6 - sensor cap.
If you lean the concentration of oxygen in the exhaust gases expanding regularly and sensor transmits to the electronic control unit signal lean (low-level signal - voltage of less than 0.45). With a mixture of enrichment (relative to stoichiometric composition) content of the oxygen in the exhaust gases decreases and the sensor transmits a signal bo ¬ Gata mixture (top-level signal - a voltage 0.45 V).
Based on these signals the electronic control unit deter-em, what the composition of the fuel-air mixture is formed at the moment of, respectively, and this cor-rektiruet opening shut-off nozzle needle.

Checking oxygen sensor
1. Warm up the engine to normal operating temperature ¬ Noah.
2. Measure the voltage of the oxygen sensor feedback ¬ ka
a) Connect the voltmeter positive lead to the conclusion, "SD" or "URT1 **" ¬ EMA diagnostic connector, and the - to you ¬ water "E1".
