"Сите овие испарувања од еко причини мора да согорат, па се враќаат назад во коморите за согорување"
tocno e se sto navede za pritisok vo karterot osven ova vo navodnici -zatoa sto iberlauf kako tehnicka izvedba se upotrebuva od samoto pronaoganje na motorite so vnatresno sogoruvanje ,a vo toa vreme blage veze nemale od EKO standardite .
Iako ima mal efekt no uljanata parea koja vlaga preku iberlauv vo filterot ,posto koga motorot ke zagree na rabotna temperatura ,klipot karikite i blokot imaat razlicno sirenje poradi toa sto se napraveni pd razlicni metali,uljnata parea koja vlaga preku iberlaufot ,stvara film koj go amortizira ili potocno dampira razlikite na stvorenite luftovi od gornata strana te na delot od klipot koj nema podmackuvanje.TE.koga se slucuva eksplozija toj film od ulje bukvalno sluzi kako amortizer od zadnata strana na prvata karika vo zlebot na klipot.
Цк, не бива.... Не ме убеди
From 1928 until the early 1960s, car and truck petrol engines vented combustion gases directly to the atmosphere through a simple vent tube. Frequently, this consisted of a pipe (the 'road draft tube') that extended out from the crankcase down to the bottom of the engine compartment. The bottom of the pipe was open to the atmosphere, and was placed such that when the car was in motion a slight vacuum was obtained, helping to extract combustion gases as they collected in the crankcase. The vacuum was satisfied by a vent, typically in the valve or valley cover, creating a constant flow of clean air through the engine's air volume. The oil mist would also be discharged, resulting in an oily film being deposited in the middle of each travel lane on heavily-used roads. The system was not positive though, as gases could travel both ways, or not move at all, depending on conditions. (Most modern diesel engines still use this type of system to dispose of crankcase fumes.)

During World War II, however, a different type of crankcase ventilation had to be invented to allow tank engines to operate during deep fording operations, where the normal draft tube ventilator would have allowed water to enter the crankcase and destroy the engine. The PCV system and its control valve were invented to meet this need, but no need for it on automobiles was recognized.

In the decades since, the legislation and regulation around emissions has tightened substantially, and the emissions of cars and light trucks have decreased substantially.
Today's petrol engines continue to use PCV systems in addition to many other emissions control measures, many of which reduce toxic exhaust emissions by relying on sensors (to collect status information for computer input), engine control units (for information processing), and actuators (to translate computer output to the changing of conditions).
