Understanding Turbochargers

Who invented the turbocharger?

• Nikola Tesla

• Alfred Buchi

• Henry Ford

• Karl Benz

What is the main purpose of a turbocharger?

• To clean exhaust gases

• To cool down the engine

• To increase engine power

• To increase fuel efficiency

What does a turbocharger use to power the compressor?

• Exhaust gases

• External air

• Electricity

• Hydraulic fluid

What is turbo normalizing?

• Increasing the turbo speed

• Cooling the turbocharged air

• Restoring air pressure to sea level pressure

• Reducing turbo lag

What is the function of a blow off valve in a turbocharger?

• To increase air pressure

• To cool down the air

• To relieve pressure when lifting off the throttle

• To filter the air

Why do turbochargers create a lot of heat?

• A. Due to the high speed of the turbine

• D. They have an intercooler

• B. Because of the friction when air molecules are compressed

• C. From the combustion process in the engine

What is the purpose of an intercooler in a turbocharged engine?

• To increase air pressure

• To reduce the temperature of the turbocharged air

• To filter the air

• To lubricate the turbo

What problem does using two smaller turbos instead of one large turbo solve?

• Cost

• Turbo lag

• Heat generation

• Air pressure

What was the first commercially available twin turbo car?

• Maserati Biturbo

• Nissan 300ZX

• Mitsubishi 3000GT

• Toyota Supra

How do sequential turbochargers alleviate turbo lag?

• By increasing the exhaust flow

• By cooling the air more efficiently

• By using a smaller turbo to spool up quickly

• By using a larger turbo only
