Pressure Lubricant System

Pressure Lubricant System

In Pressure Lubricant System the oil is used to pump with the help of pressure. The lubrication is done under pressure. the oil from the storage tank is taken by the strainer and delivers it to oil gallery, through a filter. From the oil gallery the oil is pumped to different places like crankpins, bearings, and some oil is used to pump to the cylinder walls and some falls in to the sump. 

With the help of crank pins the oil is forced to piston pins through a hole in the connecting rod web and used to lubricate the piston rings. Main gallery has  separate passing is provided at the front end for the oil to pass for lubricating the camshaft and timing gears. To get lubricate to some parts like rocker arm assemble, tappets, push rods and pumped back to the sump the oil is carried to the top of the cylinder head by the another front end of the main gallery.the oil can pump back with the help of relief valve is fitted in the oil pump.

Due to more heat absorbed by the lubricating oil some heavy duty vechile uses coolers to take the heat from oil.
