thats why manufactures of hydrocarbon especially diesel add hydrogen!!
			
		 
	 
 Refiners add hydrogen to larger molecule hydrocarbons to shorten the carbon chain, and reduce the viscosity, as well as to modify the cetane rating. Nothing to do with the energy content of the fuel. The available energy from burning a hydrocarbon can be calculated from the exothermic reaction of H2 + O2 and C + O2, less the energy needed to break the H-C and C-C bonds. No commercial fuel contains free hydrogen, as it is too dangerous (greatly lowers the flash point) and would soon be lost in any case.
 
The only possible advantage of adding minute quantities of "Brown's Gas" (or any other form of hydrogen)to the intake of a diesel would be to improve the combustion process by making up for poor atomisation or flame front progression to some extent. While this may make a perceptible improvement in an older diesel or one in poor condition, it is very unlikely that it would make any measurable difference in a modern diesel in reasonable condition. More difference would in many cases result from the effect of water carried with the "Brown's Gas" from the producer acting as a pre-cooler, and this would account for any observed results. But a water injector would be simpler, cheaper and more effective.
