I have been asked this question in class test.

This intriguing question originated from Components of a Diesel Engine Plants in section Diesel Engine Plant of Energy Engineering

Answer 1

The correct choice is (c) To eliminate friction between the mating parts

Explanation: The system includes oil pumps, oil tanks coolers and connecting pipes. The system reduces the friction between the moving parts and hence reduces wear and tear. Lubricating oil also controls the temperature at mating point.
