THE GENERAL DATA

Engine ventilation in a range from "idling to partial loading"

1. A gorjacheplenochnyj measuring instrument of air weight
2. A cover of a head of the block of cylinders
3. The oil separator chamber
Ventilation the top partial / full loading
4. A highway of soaked up air
5. A highway of deleted air
Ventilation the top partial / full loading
6. Throttle заслонка
7. A throttle in diameter of 1,1 mm
8. A soaking up tube
9. A highway of removal of air
10. A support of the pump of the amplifier of a steering
11. The oil separator chamber
12. Space for a crank
13. A retsirkuljatsionnaja pipe for oils (siphon)
14. The oil pallet
15. The management case
16. The case of a crank of the cylinder
17. A head of the block of cylinders
18. Carter of a chain
A.Svezhy air
Century Blown gases
D. A connecting element

The mix of ventilated gases is sucked in in the chamber of combustion from the chamber of a crank (12) through the chamber of a separator of oil (11) and a highway of removal of air, and also a throttle (7) in power setting from "idling to average partial loading". In an oil separator oil separates from a gas mix and arrives through a by-pass aperture and a by-pass pipe (13) in the oil pallet.

In order to avoid penetration of slags into engine oil the part of soaked up fresh air separates in a connecting element (D) and goes in кривошипную the chamber through a highway of deleted air (5), the chamber of a separator of oil (3), картер chains (18) and the case of management (15).
