What is the purpose of a turbocharger in an engine?

• To increase air density in the cylinder

• To increase cylinder size

• To cool the compressed gas

• To increase engine torque

What is the main advantage of a supercharger over a turbocharger?

• Better low speed performance

• Increased car battery load

• Increased fuel efficiency

• Reduced engine load

What is the term used for 'blowing' air into the cylinder to increase power?

• Pressure Charging

• Forced Induction

• Exhaust Backpressure

What is the air-fuel ratio (AFR) in an internal combustion engine?

• The mass ratio of air to fuel

• The pressure of the exhaust gases

• The temperature of the coolant

• The volume of the combustion chamber

What is the parameter that indicates the mass of air actually drawn into the cylinder?

• Mass Air Flow (MAF)

• Brake Power (BP)

• Volumetric Efficiency (VE)
