If the Engine idles roughly and unstably, it is necessary to check up condition КВК and a ventilating hose. The reason can consist in contamination КВК or a hose. If necessary it is necessary to replace faulty details, being guided by the instructions resulted more low. 1) to Remove КВК from an inlet collector. 2) to Start the Engine on idling. 3) to Close a finger aperture КВК for stock-taking разряжения. If разряжение is absent, to check up on a contamination hoses and an aperture in an inlet collector, and also the valve. To replace faulty details. 4) to Switch off the Engine and to dismantle КВК. To shake the valve. Knock moving запорного a valve element should be thus audible. If knock it is not audible, it is necessary to replace КВК. Sometimes, for example at strong deterioration of cylinders and piston rings or at long work of the engine with high loading etc., throughput СПВК becomes insufficiently for the admission картерных gases in an inlet collector. In these cases the part картерных gases is taken away in an air cleaner and then burns down in engine cylinders. Normal work СПВК depends on a condition of consolidations of the engine. If in engine oil there was a deposit or it became more liquid, and СПВК works normally, it is necessary to check up the Engine and to eliminate the found out malfunctions. Operation of the engine without ventilation картера can lead to an engine exit out of operation. Therefore it is important to replace in time faulty КВК and periodically to change an air filtering element (or a separator at its presence). It is necessary to check periodically a condition of ventilating hoses and their collars and to replace defective details. |
