Caterpillar

The Cat 3306 Gas Engine is a robust, 10.5-liter inline-six natural gas engine built on the legendary durability of the 3300 platform. Designed for reliable, continuous-duty operation in demanding environments, it delivers powerful, efficient, and compliant performance for critical industrial applications.
The Cat 3306 Gas Engine is engineered for continuous-duty gas compression in the oil and gas industry. Its core applications include:
Gas Lift
Gas Gathering
Wellhead Gas Compression
Advanced Digital Engine Management (ADEM A4): This electronic control system is a key technology for modern gas engines. It integrates Air/Fuel Ratio Control (AFRC), electronic ignition, governing, and comprehensive engine protection monitoring, enhancing performance and simplifying troubleshooting.
Proven Diesel-Strength Design: Inheriting the robust architecture of the diesel 3306 platform, this gas engine features a heavy-duty cast-iron block, cylinder heads, and liners, ensuring exceptional longevity and the ability to withstand high loads.
Integrated Emissions Solution: The engine is designed to meet stringent EPA standards when paired with a three-way catalytic aftertreatment system, making it a compliant choice for regulated sites.
Global Product Support: Backed by Caterpillar's worldwide dealer network, it offers extensive support including scheduled maintenance, parts warranties, and diagnostic programs like S•O•S fluid analysis to optimize service intervals and prevent failures.
