Compliance Controls EICS: Engine Integrated Control System

EICS Integrates Key Components for Engine Optimization

Optimizing your engine’s performance and maintaining emission compliance is easier than ever with Murphy’s new Engine Integrated Control System (EICS). The EICS combines many products into a complete integration package pre-calibrated specifically for your engine model. Engine Specific Kits are available for these engine models: Arrow VRG330, Caterpillar 3304NA, Caterpillar 3306NA, and Caterpillar 3306TA.

EICS combines several key components – ignition system (powered by MPI), air-fuel ratio control (powered by Compliance Controls), speed governing, interface and diagnostics, sensors, harnesses, catalyst and engine control unit (ECU) – in one package, saving you money and man-hours associated with the installation and setup of separate engine components.

The EICS has been pre-configured for your convenience, ensuring your engine will run at optimum performance without the need for manual field adjustments. Its D-EPR valve accommodates wide variations in fuel composition and speed/load ranges, maintaining efficiency with load following technology for even the toughest gas lift applications.

Murphy conducted extensive dynometer testing to ensure each specific engine will run at optimum performance across all scenarios without the need for manual field adjustments. By completing this testing upfront, operators can be certain their site will pass required testing, like Quad J testing, without the need for pretesting to get “dialed in”.


• An OEM approach to an aftermarket application
