Abstract
The regulated exhaust emissions from both natural and pyrolysis gas are compared. At a given actual air/fuel ratio, NOx from pyrolysis gas fueling was higher than from natural gas. However, because of the ability to operate the engine at higher air/fuel ratios on pyrolysis gas at comparable outputs, the differences in NOx emissions between the two fuels could be negligible. Regardless, the lowest measured NOx value at a load of 9 kw was still an order of magnitude higher than proposed US emissions standards for small generators. Further reductions in NOx emissions from SI engines will have to come from enhanced leanburn performance and/or addition of exhaust after treatment technologies. Alternatively, engines could run stoichiometrically with feedback control and a three-way exhaust catalyst as developed by the automotive industry.
