Introduction to Engine Lubrication Systems

Open Ended

Describe how the lubrication system helps maintain the performance and longevity of an engine.

Multiple Choice

Why is it important for an engine to have a lubrication system?

• To reduce friction and wear between moving parts

• To increase fuel consumption

• To make the engine heavier

• To decrease the engine's lifespan

Multiple Choice

Which component in the lubrication system is responsible for regulating system pressure?

• Oil filter

• Pressure relief valve

• Oil pan

• Pickup tube

Multiple Select

Select all components that are directly involved in drawing oil from the oil pan to the engine block.

• Oil pump assembly

• Dipstick

• Pickup tube

• Gasket seal

Open Ended

Explain the function of the oil pan and how it interacts with other components in the lubrication system.

Multiple Choice

What is used to measure the level of oil in the oil pan?

• The oil filter

• The dipstick

• The drain plug

• The oil pump

Open Ended

Describe how pressurized oil is distributed to both the upper and lower parts of the engine, and explain the role of oil galleries in this process.

Multiple Choice

Which component in a dry sump system is responsible for moving oil from the pan to the storage tank?

• Pressure pump

• Scavenge pump

• Oil filter

• Crankshaft

Open Ended

Explain how engine oil helps in reducing friction and wear in an engine.

Multiple Choice

Which of the following statements about oil viscosity is correct?

• Low viscosity oil is better for hot engine operation.

• High viscosity oil flows more easily than low viscosity oil.

• Low viscosity oil is better for cold starting operation.

• High viscosity oil is better for cold starting operation.

Open Ended

Why is it important to replace the oil filter regularly in an engine?

Multiple Choice

What is the purpose of a heat shield in the oil filter housing assembly?

• To prevent oil leakage

• To keep engine heat away from cooled oil

• To increase oil pressure

• To trap dirt particles

Multiple Choice

Where does the oil enter an oil filter?

• Through the O-ring seal

• Through the feed holes

• Through the center hole

• Through the paper element

Multiple Choice

If an oil cooler heat exchanger is fitted, where would its hoses normally directly connect to?

• The cylinder head

• The radiator

• The galleries

• The oil filter housing

Open Ended

Based on the diagrams and explanations, describe how oil travels from the oil pump to the camshaft in the engine.

Multiple Choice

Which components in the engine require lubrication provided by the oil galleries?

• Valve train components

• Radiator

• Exhaust system

• Fuel injectors

Open Ended

Explain the function of oil galleries in an engine and why they are important for engine operation.

Open Ended

How do you think the lubrication system contributes to the overall performance and longevity of an engine?

Multiple Choice

What are the main functions of a lubrication system in an engine?

• To store, clean, cool, and circulate oil to lubricate moving engine parts and bearings

• To increase engine speed

• To reduce fuel consumption

• To generate electricity
