The document outlines various types of lubrication supply systems used in engines, including the camshaft lubrication system, power take-off (PTO) systems, exhaust valve hydraulic control systems, and turbocharger bearing lubrication. Key properties for hydraulic oil in these systems include foaming resistance, air release, load carrying capacity, and water tolerance. Additionally, turbocharger lubrication requires specific criteria such as lubricity, oxidation stability, thermal stability, and anti-foaming characteristics.

6. Types OF Lubrication Supply System

12. 1. The Camshaft. Some engine designs have a dedicated lubrication
system and some use the lubricant taken from the crankcase system.
2. PTO/PTI (Power Take Off/Power Take In systems. For lubrication of
the PTO drive gear wheel

13. 3. Exhaust Valve Hydraulic Control System.
In the function of a hydraulic oil, the foaming,
air release, load carrying, and
water tolerance properties are relevant.
4 Turbocharger Bearing Lubrication.
Requirements here are for lubricity,
oxidation stability, thermal stability
and anti-foam.
