Bypass Oil filter system
2 Centrifugal type oil filter: This type of filter has four main parts; stationary casing, rotor casing, central
spindle and jetted tube. In this, oil comes to the central spindle through the inlet route. From here it goes to
the rotor casing and from the rotor casing the oil goes to the tube. Jets are fitted in these tubes, from which oil
comes out with pressure, which gives speed to the rotor casing and it starts rotating. The oil coming out of the
jet hits the wall of the stationary casing, on which dust particles remain and pure oil comes out from the outlet.
Importance of maintenance, diagnosis and Servicing
cooling system and its components
Objectives: At the end of this lesson you shall be able to
• describe about importance of maintenance, of cooling system and its components
• diagnosis of cooling system and its components
• servicing of cooling system and its components
Combustion of fuel inside a cylinder develops a very high temperature (Appx. 2200°C). At this temperature the
engine parts will expand and tend to seize. Similarly, the lubricating oil will lose its property. Therefore, it is
necessary to keep the engine temperature to operating limits. This is done by the cooling system. Heat is removed
from the engine by cooling media (water or air) and is dissipated to the atmosphere.
