Abstract: The current state-of-the-art for large-bore, stationary gas engines includes methods that can, on new engines, reduce the level of NO, emissions to 2 gm/Hp, but in general that requires a combustion system that includes a precombustion chamber, oversized turbocharger, and a control system that will maintain the proper air/fuel ratio, proper ignition timing, and other control features that will keep the engine from emitting NO. at a higher rate. When talking about methods available for retrofitting to an existing engine, there is a considerable difference in available systems. In commercially available systems, the Clean Bum system offered by several original equipment manufacturers involves nearly a complete engine rebuild, including replacing all the cylinder heads and the turbocharger, plus a control system that will operate the engine within a certain engine map. The cost of such a system is not much less than the cost of a new engine, especially if one were to compare replacing multiple old units with fewer, larger horsepower new units. Because of the expense and limited life (from an engine that may already be 30-40 years old), this is not considered a particularly viable method of NO, reduction.
