Motorcycle dual spark plug solution
Jan 14, 2024
Motorcycles using dual ignition systems include BMW, Honda, Ducati and other brands. In 2012, the Ducati Multistrada motorcycle was upgraded with dual spark plugs, resulting in more efficient combustion. This change resulted in a 5% increase in torque and a 5% improvement in fuel consumption.

Since 2003, the German BMW company has applied the new "dual spark plug ignition" technology on its new two-cylinder motorcycles such as R1100S, R1150GS, R1150R, R1150RS and R1150RT. BMW claims that this "dual spark plug ignition" technology can further improve exhaust emissions, enhance vehicle stability, and make combustion consistent over a wide range of engine operation. This improvement is to prepare for the new emission standards, including Euro II and Euro III standards. At the same time, this technology also makes it possible to improve the efficiency of the engine, which is mainly reflected in the reduction of fuel consumption.
3. Aircraft dual spark plug solution
Dual ignition systems are used on aircraft engines and have two advantages: one is to burn the fuel-air mixture more efficiently, and the other is to provide a repeatable ignition system to reduce flight engine failure accidents. So dual ignition systems usually provide dual spark plugs for each cylinder and two ignition systems (ignition coils, etc.). The dual ignition system allows the aircraft to continue flying and land safely after one of the aircraft's ignition systems fails.
For example, the Jabiru5100 is a lightweight four-stroke aircraft engine manufactured by Australia's Jabiru Aircraft.

Dual spark plugs can be traced back to some aircraft engines during World War I, such as Hispano-Suiza8, Mercedes D. III and other flight engines. Therefore, the dual ignition systems of cars and motorcycles are based on aircraft engines.
