Long duration plasma ignition
The long duration AC discharge, that is produced at the gap of a conventional sparkplug, is typically over 20 crankshaft degrees long. The discharge enables ultra lean mixtures to be used to reduce combustion temperature while maintaining the rated horsepower. This reduction in temperature is responsible for the reduction in NOx exhaust emissions. The DSI is available for low speed and high speed engines, single and dual sparkplug versions.
