2 revolutions per spark event per cylinder or once per 2 revolutions, not 2 per revolution.

Usually, systems dissipating 120 watts use fans for air cooling, and it is hard to believe that a really tiny momentary spark inside a cylinder would be 120 watts averaged over the rotation of the engine. | |
