Which of the following is NOT a type of lubrication system?
DSSSB JE - 2023,
Answer: D
The sprinkler feed system is not a lubrication system. The recognised feed systems for lubricating an engine or machine are the gravity feed (oil flows from a tank above the bearings), the splash feed (a dipper or the crank throws oil about inside the crankcase) and the force feed (a pump delivers oil under pressure through galleries to the bearings). A sprinkler feed is the name of a fire protection or irrigation arrangement, not an oil lubrication system.
