System Components and Operational Principles Quiz

Which of the following is an objective related to system components?

• Identify key system components

• Develop new system components

• Eliminate unnecessary components

• Ignore system components

Which of the following systems commonly uses splash lubrication?

• Hydraulic systems

• Manual transmission

• Open gear systems

• Pneumatic systems

Why are small enclosed systems suitable for splash lubrication?

• They require high-pressure lubrication.

• They operate in open environments.

• They have limited space for complex lubrication systems.

• They need constant external lubrication.

How does splash lubrication work in connecting rods?

• By letting parts dip into the oil and spread it around

• By using a pump to circulate oil

• By applying grease manually

• By using a fan to distribute oil

What is the role of the oil mist in splash lubrication?

• It turns into droplets that lubricate cylinders and bearings

• It evaporates to cool the engine

• It solidifies to form a protective layer

• It mixes with fuel to improve combustion

Why do plain bearings require a steady oil supply under pressure?

• To prevent the oil film from breaking down

• To increase the speed of the engine

• To reduce the weight of the engine

• To enhance fuel efficiency

Which of the following is an application of gearboxes?

• Speed reduction units

• Electrical wiring

• Hydraulic pumps

• Solar panels

How do gearboxes contribute to industrial machinery?

• By enhancing oil distribution patterns

• By reducing electrical consumption

• By increasing water flow

• By improving air quality

What role do timing gears play in an engine?

• They control the opening and closing of valves.

• They lubricate the crankshaft.

• They connect the rod bearings.

• They form the cylinder walls.

How might engine speed affect splash patterns in lubrication?

• Higher speed increases splash intensity.

• Higher speed decreases splash intensity.

• Engine speed has no effect on splash patterns.

• Lower speed increases splash intensity.
