üIn order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems.
üTwo elements have been added to the lubrication circuit in the modified engine. These elements are hydraulic lifters and an Anti-drain valve.
The analyses are done by Flowmaster7.6 and AVL EXCITE7.02 software and an accessory code.
 Finally, theoretical results are validated by a completely controlled lubrication functional test.

Modern engines are being designed to operate at high engine speeds and loads. In order to fulfill the requirements of developing new engines, lubrication system must be improved.

Yiqing Yuan et al, in 2007, established a methodology for predicting lubrication flow in the rod bearings and oil circuits that can be used to guide engineering designs.
Yaguo Lu et al. [10], in 2009, developed a software for simulating aero-engine lubrication system.

In this paper, two important components, chain tensioner and anti-drain valve, have been investigated as well as other components in the lubrication system.

Engine description

There are three important reasons for improving the base engine to the modified engine:

(1) using inexpensive and locally abundant CNG fuel,

(2) demanding higher power and

(3) modifying weaknesses of the base engine. The engine parameters are listed in table.

Lubrication functional test

This test is applicable to Diesel and Gasoline engines.

After installing the sensors in particular locations of lubrication circuit like the main gallery, oil pump outlet, oil filter inlet and outlet, the end side of the hydraulic lifter gallery, the engine is configured on the dynamometer and prepared for lubrication functional test. This test is divided into steady state and transient parts.
