Fundamentals of Turbochargers

Refer to the diagram of the turbocharger system. Which part of the system is driven by the engine exhaust flow?

• Compressor

• Air Cleaner

• Turbine

• Engine

The Rootes Blower is mechanically driven, while the Turbocharger is driven by exhaust gases.

• True

• False

Turbochargers can increase air intake by as much as ______%, allowing for a doubling of power output.

• 300

• 50

• 100

• 200

Fill in the blank: Doubling the compression pressures can improve the engine's ________ output.

• power

• noise

• weight

• color

Increasing boost pressure improves fuel ignition by creating higher compression pressures and temperatures.

• True

• False

Emission production dramatically declines when turbochargers are added.

• True

• False

According to the Fundamentals of Turbochargers, should visible emissions be seen coming out of the exhaust from an engine built after 1998?

• Yes

• No

According to the Fundamentals of Turbochargers, what effect do turbochargers have on engine noise emissions?

• Increase the amount of noise coming from the exhaust and intake manifold

• Reduce the amount of noise coming from the exhaust and intake manifold

• Have no effect on engine noise

• Only affect intake noise

Turbocharger effectiveness ______ as altitude increases.

• increases

• decreases

• remains the same

• fluctuates

An engine equipped with a turbocharger at higher altitudes acts in which of the following ways?

• It maintains power more effectively than a non-turbocharged engine.

• It loses more power than a non-turbocharged engine.

• It operates less efficiently than at sea level.

• It cannot function at all.
