Cat Issues Upgrade For G3516 LE Engines
The upgrade kit allows operators to modify existing engines
Caterpillar Oil & Gas has released a low-emission upgrade kit for select G3516 LE petroleum engines used in gas compression applications.
The upgrade 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.
Caterpillar said the upgrade is an economic, minimally invasive solution that allows the engine to offer the same power, 1340 bhp (1 MW) at 1400 rpm, and fuel tolerance while increasing altitude and turndown capability.
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 (AFRC) and a NOx sensor. Upgrade kits also are available to bring engines up to this configuration.
