Quiz Answer Key and Fun Facts
1. Which of the following is an advantage of fuel injection?

Answer: Distribution of fuel to cylinders more uniform

Fuel injected engines are often difficult to start when hot because heat inside the cowling can cause the fuel in the lines to vapourise.
2. The speed, and thus efficiency, of the turbine in a turbocharger depends on the pressure difference between the exhaust and the outside air.

Answer: True

A greater difference means that there is less inverse pressure on the exhaust gasses as they leave the engine, so the turbine spins faster and the compression of the turbocharger is much higher.
3. A supercharger uses no more than 4 percent of the engine's power to operate.

Answer: False

As much as 16 percent of the engine's power is used to operate the supercharger.
4. Inside the cylinder, the combustion stage can produce temperatures as high as _____ degrees Celsius. (indicate #)

Answer: 2500

A great deal of this heat is absorbed by engine parts, which would be fused together if the heat was not vented by means of air and/or liquid cooling.
5. A "rich" fuel mixture means that the engine is getting too much fuel for the amount of air it is receiving, and therefore is BURNING too much fuel.

Answer: False

It is true that a "rich" fuel mixture means that the engine is getting too much fuel for the amount of air it is receiving, but the engine is not burning most of this fuel, instead, most gets dumped from the exhaust system. (The engine is wasting fuel, but not burning it)
