Engine Design

- Engine design built on G3500 proven reliability and durability - Ability to burn a wide spectrum of gaseous fuels - Robust diesel strength design prolongs life and lowers owning and operating costs - Broad operating speed range at lower site air densities (high altitude/hot ambient temperatures) - Higher power density improves fleet management - Quality engine diagnostics - Detonation-sensitive timing control for individual cylinders


When configured with customer-supplied air fuel ratio control and three-way catalyst, the engine is capable of meeting NSPS and non-attainment area emissions levels.

Advanced Digital Engine Management

ADEM A4 engine management system integrates speed control, air/fuel ratio control, and ignition/detonation controls into a complete engine management system. ADEM A4 has improved: user interface, display system, shutdown controls, and system diagnostics.

Full Range of Attachments

Large variety of factory-installed engine attachments reduces packaging time


Every engine is full-load tested to ensure proper engine performance.
