6.3. Control of emission of crankcase gases
GENERAL INFORMATION

To reduce emission of not burned hydrocarbons from a case in the atmosphere, at the tight engine, crankcase gases and oil vapors are delayed from a case through an oil separator of a wire grid in the treatise of air supply in the engine and burned up by the engine.

At a high depression of a collector (idling, delay) gases will be exhausted from a case. At a low depression of a collector (acceleration, completely open butterfly valve) gases come out a case with rather more high pressure in an engine case, and also if the engine is worn-out, high pressure in an engine case (because of the increased break of gases) will force a stream to come back to a collector.
