The U.S. Environmental Protection Agency (EPA) introduced progressively lower emissions standards for stationary spark-ignited engines in phases, with further reductions planned. The challenge for manufacturers like Cummins Inc. is to keep up with these moving targets in engine and emissions control technology design.

While federal emissions levels are demanding, localized rules and nonattainment area standards often prove more stringent, creating additional complexity. Meeting these various standards becomes particularly challenging for operators with dispersed compressor packages across regions. The decision of whether to opt for an EPA-certified engine adds another layer of complexity, impacting responsibilities for emissions control and maintenance.

Addressing these challenges, Continental Controls Corporation has introduced electronic gas carburetors (EGCs) as solutions for both retrofitting existing compressor units and enhancing new ones. These EGCs work with catalytic converters and offer emission reduction, fuel efficiency improvement, and reduced engine maintenance. This technology enables compliance with emissions standards without requiring additional exhaust after-treatment, providing operators with enhanced flexibility and control.
