Lubrication System

What is one of the main functions of an engine's lubrication system?

• To increase friction
• To reduce wear and corrosion
• To slow down the engine
• To increase engine noise

Which component holds the oil supply in an engine?

• Oil filter
• Pressure relief valve
• Oil pan (sump)
• Oil pump

What is the primary purpose of the oil filter?

• To increase oil pressure
• To add oil additives
• To remove microscopic particles from the oil
• To cool the oil

How often should the oil filter typically be replaced?

• Every week
• Every month
• With every oil change
• Every year

What does the pressure relief valve in an engine's lubrication system do?

• Increases oil pressure
• Relieves excessive oil pressure
• Cools the oil
• Filters the oil

Which type of lubrication is used when high-speed bearings and components are being forced together?

• Boundary lubrication
• Dry lubrication
• Hydrodynamic lubrication
• No lubrication

In a dry sump lubrication system, where is the oil stored?

• In the oil pan (sump)
• In a separate storage tank
• In the oil filter
• In the pressure relief valve

What is the term for oil's flow rate?

• Density
• Viscosity
• Pressure
• Temperature

Which component is responsible for generating oil pressure in the lubrication system?

• Oil filter
• Oil pan (sump)
• Oil pump
• Pressure relief valve

What does SAE stand for in relation to oil viscosity ratings?

• Society of Automotive Engineers
• Standard Automotive Equipment
• Standardised Oil Engineers
• Society of Engine Additives
