A nanoscale diesel technology has been tested that shows remarkable promise for reduction in NOx and PM. The technology is also a natural vehicle for extracting energy from renewable liquid fuel streams. The combustion process is altered in a fundamental manner that will allow diesel engines and liquid fuel fired turbines to compete with natural gas fired engines.
Electrostatic spray units have been optimized over a forty year span in support of agricultural systems. The systems have evolved to a point where they deliver a large quantity of negatively charged water in an ultra-fine mist. The charge mist induces water to stratify into one nanometer diameter crystals with significant catalyzing properties. Once aspirated into a diesel engine the water nanosclusters catalyze combustion reactions at an increased rate at lower peak temperatures.
The increased rate of reaction in the diesel cylinders provides more expandable gas early in the expansion stroke, which in turn results in significant efficiency gains. Charged water fumigation (CWF) has been evaluated on five separate engines with uniformly positive test results. The efficiency increased by 15%, PM was reduced by over 95% and the NOx was reduced by over 60%.
