System of operated ventilation of a case (PCV) - the general information, check of a condition and replacement of components

General information

Entering into an obligatory complete set of engines of all models considered in the real Management the PCV system serves for decrease in issue in the atmosphere of hydrocarbonic connections at the expense of a conclusion from the engine of karterny gases. The purge of the block is carried out by pro-race of fresh air arriving from an air purifier through a case in which it mixes up with the collected evaporations and broken of chambers of combustion by gases and deduced via the PCV valve in the inlet pipeline. The principle of functioning of system of operated ventilation of a case is presented on an illustration.


The PCV valve, air inlet and set of the hoses connecting listed devices to the engine belong to number of the main components of system.

For the purpose of maintenance of stability of turns of idling the PCV valve blocks a purge stream at deep depression in the inlet pipeline, failure of the valve can bring to unexpected остановам the engine and to sharp jumps of turns.


Violation of serviceability of functioning of system of ventilation can lead a case to violation to stability/decrease in turns of idling, up to spontaneous останова the engine, to development of leakages of oil, formation of a tarry raid on internal surfaces of the unit.

Check of serviceability of functioning of the PCV valve

 PERFORMANCE ORDER

1. Disconnect from the PCV valve a ventilating hose. Remove the valve from the engine (turn out it or take from the landing plug in a cover of a head of cylinders). After valve removal again connect to it a ventilating hose.

2. Start the engine on single turns and press a finger to an opening in the valve, - in assembly depression should take place.

3. If depression it is not felt, at first check passableness of a hose, then (if a hose as it should be), muffle the engine, liberate the valve from a hose and by means of a thin core check freedom of a course of its plunzher, - the core is entered into an opening with the equipped carving of the party of assembly.

When stirring the serviceable valve should publish a crash.

4. In case of need make replacement of klapanny assembly.


Replacement

 PERFORMANCE ORDER

1. Turn out the valve from the nest in a cover of a head of cylinders, or having pulled vertically up, take it from the rubber landing plug. Estimate a plug condition, in case of need make replacement.
2. If the valve is hammered by tarry deposits, the probability of violation of passableness of a connecting hose is not excluded also, - remove a hose and wash out it solvent.
3. Having washed out a hose, check it on existence of signs of aging of a material and mechanical damages. Track reliability of fixing of a hose on reception unions.
4. In case of need make PCV valve replacement.
