1.

What is the main function of a lubrication system?

a)

Increase the temperature of the parts.

b)

Improve the aesthetics of the components.

c)

Reduce friction between moving parts.

d)

Facilitate the assembly of the parts.

2.

What type of lubricants are used in heavy vehicles?

a)

Engine oils, bearing greases, fluids for transmissions and differentials.

b)

Food greases

c)

Lubricants for household appliances

d)

Cooking oils

3.

Why is lubrication important in vehicle engines?

a)

Lubrication is unnecessary in modern engines.

b)

Lubrication increases friction in the engine.

c)

Lubrication is important because it reduces friction, prevents wear, and helps maintain the proper temperature in the engine.

d)

Lubrication is only needed in race vehicles.

4.

What components are part of a lubrication system?

a)

Oil reservoir, lubrication pump, filters, pipes, lubrication points.

b)

Starter battery

c)

Cooling system

d)

Fuel tank

5.

How is the lubrication system differentiated in small and heavy vehicles?

a)

Small vehicles use high viscosity oils, while heavy ones use lighter oils.

b)

Small vehicles use simple lubrication systems, while heavy ones use complex systems and higher viscosity oils.

c)

Heavy vehicles require a simpler lubrication system than small vehicles.

d)

Both types of vehicles have identical lubrication systems and use the same type of oil.

6.

What consequences can result from inadequate lubrication?

a)

Improvement in product quality

b)

Increase in energy efficiency

c)

Reduction in operating costs

d)

Premature wear, overheating, and mechanical failures.

7.

What type of oil is recommended for light vehicles?

a)

Olive oil

b)

Synthetic or semi-synthetic oil with appropriate viscosity.

c)

Mineral oil with high viscosity

d)

Engine oil for heavy machinery

8.

How is the lubrication system maintained?

a)

Clean the inside of the engine

b)

Check the brake system

c)

Adjust the vehicle's brakes

d)

Check levels, clean filters, verify pumps and hoses, change lubricant.

9.

What is the pressure lubrication system?

a)

It is a process that cools the engine by circulating water.

b)

It is a method that uses a pump to distribute lubricating oil under pressure to the moving parts of an engine or machinery.

c)

It is a method that applies grease instead of oil to the moving parts.

d)

It is a system that uses compressed air to lubricate the engine.

10.

What are the signs of a defective lubrication system?

a)

Reduction of friction

b)

Improvement in engine performance

c)

Unusual noises, increased temperature, smoke, excessive wear.

d)

Increased pressure in the system
