What primary purpose does the Collector/Surge Tank serve?

• Collects all liquids in fuel tanks to make it easier to remove water and contaminants

• Provides a central spot for fuel transfer to be initiated from

• Prevents engine fuel starvation due to sloshing

• Feeds the fuel vent system

The process by which crude oil is heated and separated into lighter compounds is called

• Blending

• Fracking

• Distillation

• Pasteurization

The energy content of a fuel is dependent on to its

• Volitility

• Density

• Pour Point

• Flammability

Avgas and Jet fuel are interchangeable

• At any time

• Only in emergencies

• Sometimes in turbine engines

• Only is high performance piston engines

The color of Avgas 100ll is

• Green

• Blue

• Red

• Purple

The color of 80 Octane Avgas is

• Blue

• Red

• Green

• Straw

The "Octane" number of a fuel is a measure of its ability to burn without

• Leaving residue

• Detonating

• Overheating

• Causing vapor lock

A hydrocarbon obtained from crude oil that is highly resistant to detonation is

• Propane

• Hydrogen

• Octane

• Heptane

Higher octane fuel will increase the HP produced by a piston engine

• When used in a fuel injected engine

• When used in a Diesel engine

• Higher octane fuel will not increase HP

• Only in a turbine engine

This occurs when a "hot spot" in a piston engine cylinder causes the fuel/air mixture to ignite too early

• Detonation

• Preignition

• Knocking

• Spark plug fouling
