Correct Answer - Option 1 : pressure feed
Explanation:
Splash lubrication system: The splashing action of oil maintains a fog or mist of oil that drenches the inner parts of the engine such as bearings, cylinder walls, pistons, piston pins, timing gears etc. The splash oil then drips back into the sump.
This system is commonly used in a single-cylinder engine with the closed crankcase
Forced feed or pressure lubrication system: This system is commonly used on the high-speed multi-cylinder engine in tractors, trucks and automobiles
Wet sump lubrication system:
In the wet sump system, the bottom of the crankcase contains an oil pan or sump from which the lubricating oil is pumped to various engine components by a pump. After lubricating these parts, the oil flows back to the sump by gravity. There are three varieties in the wet-sump lubrication system.
- the splash system
- the splash and pressure system
- the pressure feed system
