What are the two types of hydrocarbons found in gasoline that are used to determine octane rating?
Isooctane and normal heptane
How’s the octane rating of gasoline determined?
By calculating the percentage of isooctane mixed with normal heptane
Why did the need arise to develop aviation fuel with octane ratings beyond 100?
To combat detonation in more powerful engines with higher compression ratios
What characteristic of aviation gasoline helps prevent fuel system problems?
Its chemical composition that minimizes gumming and corrosion
Under what conditions is an aircraft engine most susceptible to detonation?
At high power settings with improper leaning
