The Dynamic Spark Ignition (DSI) replaces the electronic ignition system in automobile and industrial engine applications. The DSI produces a long duration, multi-frequency AC discharge at the gap of a conventional style spark plug; a plasma discharge. The duration of the discharge measures 30 degrees in crankshaft degrees as compared to less than 1 degree for a conventional ignition system. The long duration and multiple energies favorable affect the air and fuel mixture to easily initiate combustion charge. As a result of the gases ionized at the spark plug, the discharge is qualified as a plasma.
Plasma is one of four fundamental states of matter ( the others being solid, liquid and gas). When air or gas is ionized, plasma forms with conductive properties similar to those of metals. The DSI forms a plasma between the electrode and cathode of a common spark plug. The ionized gas is formed by freeing electrons created by a strong and oscillating electric field which causes an avalanche and multiplication of ion impacts. This freeing of electrons creates free radicals that are the beginning of combustion.
The DSI enables stable combustion using lean air fuel ratios that haven’t been achievable using pre-combustion chambers and only for industrial engines providing more power, faster acceleration and reduced fuel consumption. The industrial engine version has reduced NOx and CO to below EPA requirements.
