Here are the basic equations, where CH represents a generic hydrocarbon fuel, such as coal or wood. There are other constituents, such as nitrogen and sulfur, but they are not part of the reaction.

CH + 5/4 O2 --> CO2 + 1/2 H2O normal combustion, exothermic (produces heat)
CH + H2O --> CO + 3/2 H2 endothermic reaction (requires heat)
CH + 1/2 O2 --> CO + 1/2 H2O incomplete combustion, slightly exothermic

The resulting gas mixture of CO, H2, and N2 (inert) is very low in energy content, about 200btu/cuft compared to natural gas CH4 at 1000btu/cuft. My question is; how do you burn this gas in a spark iginiton internal combustion engine that requires a near perfect air/fuel ratio? Do they run it in diesels? If so, how does the fuel injection system work?
