System of a perepuskaniye of the soaked air – the general information, check of a state and substitution of a diaphragm of the valve IAB

General information

Some models are equipped of the system IAB that supplies a possibility of a perepuskaniye of the air that is absorbed in the motor in the combustion camera. The entry oil pipeline in such models is equipped of two air channels that there allows the motor optimizes the air provision depending on specific conditions of his functioning. The very efficiency of the return is got due to the operation of switches of valves depending on the current turns of the motor. The shut valves position allows to try to obtain the very torque in low turns of the motor, services opened to obtain the very power in high turns.

To check

ORDER OF REALIZATION

1. In the dead motor desconectam a hose of vacuum of a diaphragm of IAB and they join to a last one the bomb of manual vacuum (companion sees an illustration). If the stick of a diaphragm property remains, substitute the meeting. 2. In the motor that works in the only turns they secure the depression available in the open end of the hose of vacuum off. The depression has to happen wasting time, disappearing in the increase in the frequency of the rotation of the motor to 6.000 revolutions per minute. 3. If in the only turns the depression if it is going away, walks in a hose of vacuum of a diaphragm to the valve of the management located below the oil pipeline of entry and besides that – to the vacuum tank. Desconecte to hose that goes from the tank to the entry oil pipeline and the depression existence checks it. If the depression if it is going away, checks an existence of hose of slits and signs of the blockade. 4. Disunite the capture of the valve IAB eletromagnética (companion sees an illustration). One to positive probe of a voltômetro to the capture of a blue-red wire in the capture of a braid, negative – to the capture of a black wire. In the ignition included the tension of battery it has to happen. If the tension if it is going away, checks a condition of an electrical system and the quality of his connections of contact. 5. If the tension will happen, and vacuum lines like debit to be, to substitute the valve eletromagnética.

Substitution

ORDER OF REALIZATION

1. Since the substitution of a diaphragm results screws of his fixation (companion sees an illustration). 2. Since the substitution of the meeting of the valve eletromagnética with the vacuum tank weakens a collar of fixation (companion sees an illustration). 3. The installation is done upside-down.
