A wasted spark is when in an ignition system in a four-stroke cycle internal combustion engine spark plugs fire in pairs, on both the exhaust and compression strokes. The extra spark on the exhaust stroke has no effect and is thus "wasted". This design is simpler than a conventional ignition system, but the extra sparks reduce the lifespan of components (contact breaker, spark plugs).Examples of engines using this design include the Buick V6 engine Series I and newer, Harley Davidson V-Twin, air-cooled BMW Motorcycles, Citroen 2CV, Mazda B engine, Chrysler V10, PSA TU Engines, Volkswagen Mark 3 2.8 VR6 (other than 2.0 ), Saturn Corporation 4 cylinders, and Chrysler Neon engines. Some Ford engines also do. Many Honda and Kawasaki motorcycle and PWC engines also follow a similar design, to allow for a smaller number of more powerful coils to replace a larger number of smaller coils in the same limited space.
