CH2: Internal Combustion Engine (ICE) - W3

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

• Naturally Aspirated

• Exhaust Backpressure

What is the purpose of engine cooling?

• To maintain the engine at optimum operating temperature

• To increase engine torque

• To reduce exhaust gas emissions

• To improve low speed performance

What does Volumetric Efficiency (VE) indicate in an engine?

• How well the engine 'breathes'

• The rate of fuel consumption

• The air-fuel ratio

• The mass airflow

What is the measurement type of fuel efficiency within a reciprocating engine?

• Brake Specific Fuel Consumption (BSFC)

• Cylinder Pressure

• Engine Friction

• 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)

• Engine Friction

What is the term used for the pressure that the engine exerts on the exhaust gases?

• Exhaust Backpressure
