Ignition Component fuel moisture (FFM) which expresses the effective moisture content of the fine fuels. The closer the initial temperature of the fuel is to the ignition temperature, the more likely a fire will result when a firebrand in introduced into the fine fuel complex, since not a much energy is required to raise the fuel particle to its ignition temperature. Ignition Component The Ignition Component is a number which relates the probability that a fire will result if a firebrand is introduced into a fine fuel complex. The ignition component can range from 0 when conditions are cool and damp, to
Ignition magneto as larger engines may be too difficult to crank at sufficient speed to operate a magneto, even with an impulse coupling. As the reliability of battery ignition systems improved, the magneto fell out of favour for general automotive use, but may still be found in sport or racing engines. Engines which power Top-Fuel drag-racing cars, which burn nitro-methane fuel require three spark plugs in the cylinder driven by three magnetos because the nitro-methane fuel mixture burns so slowly. Ignition magneto An ignition magneto, or high tension magneto, is a magneto that provides current for the ignition system of a spark-ignition
