The Caterpillar G3516 industrial gas engine is purpose-built for continuous-duty stationary power plants and gas compression stations operating on pipeline natural gas, associated petroleum gas (APG), biogas, or coal-mine methane. It delivers high electrical efficiency and low NOx emissions.
Key Engineering Features:
- ADEM electronic engine management governing ignition timing, air-fuel ratio, and knock detection.
- Individual cylinder ignition coils for consistent spark energy and extended spark plug service life.
- High-temperature alloy valve seats and valves specifically metallurgy-matched for dry gas combustion.
- Broad fuel tolerance adaptable to varying gas heating values and methane numbers.
The Cat® G3516 is a heavy-duty V16 four-stroke spark-ignited gas engine. Equipped with turbocharged aftercooling and Caterpillar ADEM electronic controls, this 69L unit produces up to 1029 kW at 1200–1400 rpm. Optimized for continuous stationary applications including power generation and gas compression, it offers wide natural gas fuel compatibility, solid durability and comprehensive monitoring for dependable, cost-effective operation.
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
Emissions
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.
