The Dutch Hydroxide Organisation developed a highly sophisticated retrofit technology which optimizes the combustion for large industrial diesel combustion engines.
The implementation of this technology increases fuel efficiency, extends mechanical reliability and decreases exhaust emissions of the diesel combustion engine. By introducing a catalyst-gas into the air-intake of the engine, the combustion process is optimized. The catalyst-gas is produced on-board and on-demand by the Fuel-Emission-Reduction (FER) System. There were others catalyze the symptoms, TDHO deals with the cause.
