 W. Thor Zollinger; Cleaning up Diesel and Automotive Exhaust with Hydrogen

Summary: Addition of hydrogen to the air intake of a combustion engine can dramatically cut the pollutants in the engine's exhaust. Reductions up to 50% have been observed in studies, some dating back into the 1950's. ........The main benefit, however, is a reduction in exhaust emissions, which is fast becoming more important to independent truckers. ...... 

Het bekende NASA rapport over toevoeging van waterstof aan verbrandingsmotoren:

An experimental program using a multicylinder reciprocating engine was performed to extend the efficient lean operating range of gasoline by adding hydrogen. Both bottled hydrogen and hydrogen produced by a research methanol steam reformer were used. These results were compared with results for all gasoline. ..... All emission levels decreased at the leaner conditions. Also, hydrogen addition significantly increased flame speed over all equivalence ratios. Engine performance and emissions with hydrogen from the methanol reformer were about the same as those with bottled hydrogen.

Vervolgens heeft de Universiteit van Oldenburg onderzoek gedaan met een motorstand. het is de kunst om niet te vroeg het water(stof)gas in te brengen. je verschiet dan te vroeg je kruit:

Abstract: Since the early years of internal combustion engine development, many researchers have been trying to optimize the combustion process in the engines’ chambers. The utilization of hydrogen as a combustion enhancer have also been investigated during the years of the machine-dominated era, but the results were dubious. Therefore Hydrogen Enhanced Combustion (HEC) is not yet being commercially used. The aim of the following document is to present the milestones of the results on the HEC research, as well as the potential applications and the present state of the art on this field. Finally the possibility of on board hydrogen production with plasma reformer is also briefly presented and investigated.
