Dual Ignition is a system for spark-ignition engines, whereby critical ignition components, such as spark plugs and magnetos, are duplicated. Dual ignition is most commonly employed on aero engines,〔Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 177. Aviation Supplies & Academics, 1997. ISBN 1-56027-287-2〕〔Aviation Publishers Co. Limited, ''From the Ground Up'', (27th revised edition), page 67, ISBN 0-9690054-9-0〕 and is sometimes found on cars and motorcycles. Dual ignition provides two advantages: redundancy in the event of in-flight failure of one ignition system; and more efficient burning of the fuel-air mixture within the combustion chamber.〔〔 In aircraft, redundancy is the prime consideration, but in other vehicles combustive efficiency is the target. ==Design== A dual ignition system will typically provide that each cylinder has twin spark plugs, and that the engine will have at least two ignition circuits, such as duplicate magnetos or ignition coils.
