Step by Step Solution

There are 3 Steps involved in it

Step: 1

1 A wet sump lubrication system is a type of engine lubrication system where the oil is stored in the engines crankcase or oil pan The oil is drawn from the sump by the oil pump and circulated throughout the engine to lubricate the moving parts 2 A dry sump lubrication system is a type of engine lubrication system where the oil is stored in a separate oil tank rather than in the engines crankcase or oil pan The oil is drawn from the tank by the oil pump and circulated throughout the engine and then returned to the tank 3 The viscosity of engine lubricating oil refers to the oils resistance to flow It is a measure of the oils thickness or fluidity The viscosity of the oil is important because it affects the oils ability to lubricate the engines moving parts effectively 4 In an aircraft reciprocating engine the oil temperature is controlled through ... blur-text-image
