Supercharger Functionality Quiz

How are superchargers typically driven in an engine?

• By solar power

• By a belt connected to the engine's crankshaft

• By exhaust gases

• By electric motors

What is the result of using a supercharger in an engine?

• Decrease in power output

• Increase in power output

• Decrease in air pressure

• Increase in fuel consumption

What is a common feature of Positive Displacement Superchargers?

• They provide variable boost pressure.

• They deliver a constant volume of air per revolution.

• They are less efficient at low speeds.

• They are primarily used in aviation.

What is the main advantage of Twin-Screw Superchargers over Roots Superchargers?

• They are less efficient.

• They generate more heat.

• They offer a good balance of power and efficiency.

• They are less common in automotive applications.

In what year was the Roots blower invented?

• 1900

• 1860

• 1885

• 1920

What is the term used for the pressure increase in a Roots supercharger when air encounters higher pressure in the intake manifold?

• Internal compression

• Isochoric compression

• Thermal compression

• Dynamic compression

What feature do modern Roots-type superchargers often have to improve efficiency?

• Two-lobe rotors

• A slight helical twist

• Internal cooling systems

• Larger housing

What is the primary function of the lobes in Roots superchargers?

• To compress air internally

• To mesh together and trap air

• To cool the air

• To increase fuel efficiency

How does the pressure increase in a basic Roots blower?

• By internally compressing the air

• By heating the air

• When moving air encounters higher pressure in the intake manifold

• By using a turbine

What is the term used for the pressure increase method in Roots superchargers?

• Isothermal compression

• Adiabatic compression

• Isochoric compression
