Application: Natural Gas Rich Burn Emission Control


Three-way catalysts reduce emissions dramatically in natural gas rich burn engines. Minimum emissions, however, are only achieved if the air-fuel-ratio control holds the ratio within a very narrow window, with many variables affecting the equations. And if your business depends on one of these engines, you know that emission controls can be problematic for this reason. With the tight EPA NSPS emission regulations, it is important for businesses to have a system that can keep the engine in compliance for longer periods of time, over a wider range of conditions.
