Wasted Spark

Wasted as Spark ( made ​​Engl. " Wasted spark" ) is a type of ignition is called in internal combustion engines, wherein the spark plug in two cylinders at the same time just prior to top dead center ( TDC) of light, even at the end of compression and even during the ejection phase. The second ignition has no influence on the engine performance. This technique is simpler than conventional ignition methods and is mostly used in resting ignitions.

Engines equipped with this ignition system:

• BMW motorcycles of the R series up to 2004
• Audi six-cylinder V-engines
• Buick six-cylinder V-engines
• Harley -Davidson V -Twin
• Dnepr and Ural motorcycles with two-cylinder boxer engine
• Citroën 2CV
• Mazda
• Chrysler V10 and neon.

In addition, some Ford engines and motorcycle engines from Honda and Kawasaki are equipped with it. For smaller four-stroke stationary engines to find this principle is also often because the magneto ignition located on the engine flywheel manages the not externally accessible camshaft without additional contacts or donor.
