Engine Lubrication Quiz

What is one of the main purposes of engine lubrication in internal combustion engines?

• To increase fuel consumption

• To rapidly wear engine components

• To adequately lubricate all moving parts

• To decrease engine temperature

What could happen to engine components if there is a lack of lubrication?

• They would become more efficient

• They would rapidly wear and seize

• They would increase in size

• They would cool down

How does the lubrication system help in maintaining engine components?

• By increasing friction

• By cooling engine components

• By reducing engine size

• By increasing engine noise

What role does lubrication play in relation to piston rings and cylinder bores?

• It helps to seal the piston rings to the cylinder bores

• It increases the gap between piston rings and cylinder bores

• It removes the piston rings

• It heats the cylinder bores

How does the lubrication system help in dealing with harmful deposits in the engine?

• By burning them

• By holding them in suspension

• By increasing their size

• By ignoring them

What protection does the lubrication system provide to the engine?

• Protection from overheating

• Protection from corrosion

• Protection from noise

• Protection from fuel consumption

What is the purpose of engine lubrication?

• To increase the friction between surfaces

• To make engine components look smoother

• To reduce the friction between surfaces

• To generate more heat in the engine

What happens to engine components when viewed under a microscope?

• They appear perfectly smooth

• They have a rough surface finish

• They look larger than they are

• They appear to be transparent

What would occur if no lubrication is applied to engine components?

• Components would become cooler

• Friction would decrease

• Wear would quickly occur

• Components would become smoother

What is the primary purpose of engine lubrication?

• To increase friction between surfaces

• To create an oil film that reduces friction

• To separate surfaces and increase wear

• To generate heat between moving parts
