Power Making Fuel Characteristics Octane Rating Burning Rate Latent Heat of Vaporization Energy Value

Three common octane ratings for motor fuels:

(R+M/2) method,[object Object]

High MON rated fuels allow the use of higher compression and advanced spark timing,[object Object],[object Object]

There is less time for fuel to burn at high RPM’s, so rapid burning fuel is a must in racing,[object Object],[object Object]

Measured in BTU’s per gallon

Higher rated fuels remove heat better,[object Object]

Reducing temperatures in the engine and oiling system components,[object Object]

Horsepower generation depends on “Net Energy Value” - Equal to the energy value multiplied by the amount of fuel that can be burned,[object Object]

Lower stoichiometric fuels allow more fuel to be burned which, in turn, increases the Net Energy Value of the fuel,[object Object],[object Object]
