Caterpillar Oil & Gas offers a low-emission engine upgrade kit for select G3516 LE petroleum engines used for gas compression. The kit allows operators to modify existing engines to a lower emission configuration, enabling operation at 0.5 or 1.0 g/bhp-hr NTE NOx levels. The upgrade gives the engine the same power and fuel tolerance while increasing altitude and turndown capability. The power rating for the G3516 LE will remain the same at 1,340 bhp @ 1,400 rev/min. Local dealers are available to bring current engines up to the latest technology, regardless of where the engine is in its life cycle. New components in the kit include a two-stage aftercooler, venture fuel mixer, turbochargers, oil cooler, air cleaners, gas shutoff valve, and software. Existing engines must have the ADEM A3 engine control module, air fuel ratio control, and a NOx sensor.
