Forced Induction and EGR

Name 2 types of Forced Induction

• Megacharger

• Turbocharger

• Supercharger

• Hypercharger

• Megadrive

What part of the turbo is numbered 1?

• Compressor

• Shaft

• Rotator

• Turbine

What drives a turbo charger?

• Exhaust Gas

• Intake Gas

• Belt driven from crankshaft

• Belt driven from camshaft

What does EGR stand for?

• Exciting gear rotation

• Exit gas regurgitation

• Exhaust gas recirculation

• Exhaust gas resistance

• Existing gas recycling

 A supercharged engine has a volumetric efficiency of –

• under 90%

• 90%

• 100%

• over 100%

What drives a Supercharger?

• Exhaust Gas

• Intake Gas

• Belt Driven from camshaft

• Belt driven from crankshaft

What does the EGR system connect from and to?

• From inlet manifold to exhaust silencer

• From catalytic converter to MAF sensor

• From exhaust manifold to Inlet manifold

• From exhaust valves to downpipe

 Why are vehicles fitted with EGR?

• To provide a better stoichiometric ratio

• Increase cylinder temp to achieve combustion quicker

• Reduce cylinder temp and reduce production on NOx

• To increase fuel consumption

What is the purpose of a turbocharger wastegate?

• To control the amount of fuel injected

• To control the amount of boost pressure

• To control the amount of oil flow through the turbo

• To control the amount of airflow into the turbo

Answer explanation

By redirecting a portion of exhaust gas away from the turbine wheel, we can reduce the speed of the compressor wheel, therefore reducing boost pressure.

What is component 'A'?

• EGR cooler

• EGR valve

• Supercharger

• Turbocharger

• Intercooler
