Benefits and Features

- Industry-leading power with ambient-based rating capability - ADEM4 engine control system provides complete engine control, monitoring, and protection while maintaining emissions. - Widest fuel tolerance in the industry for application flexibility - Proven reliability and durability with the lowest owning and operating costs - Factory-installed thermostats

Meets U.S. EPA Spark Ignited Stationary NSPS Emissions for 2010 with the use of an oxidation catalyst

Lean-burn engines operate with large amounts of excess air. The excess air absorbs heat during combustion reducing the combustion temperature and pressure, greatly reducing levels of NOx. Lean-burn design also provides longer component life and excellent fuel consumption.

Includes engine mounted thermostats, compress oil cooler connections, jacket water and lube oil heater connections.

ADEM4 engine management system integrates speed control, air/fuel ratio control, and ignition/detonation controls into a complete engine management system. ADEM4 has improved: user interface, display system, shutdown controls, and system diagnostics.

GERP is a web-based program designed to provide site performance capabilities for Cat® natural gas engines for the gas compression industry. GERP provides engine data for your site's altitude, ambient temperature, fuel, engine coolant heat rejection, performance data, installation drawings, spec sheets, and pump curves.
