Auxiliary Engine (Generator Set) · Auxiliary Engines
The marine auxiliary engine category includes the Cummins 6L6CTA8.3-G2-60Hz model. This engine, part of the 6CTA8.3-G2 family, is designed for maritime applications with a power output of 252 kW at 1800 rpm and operates on MDO fuel. It features four turbochargers (two low-pressure and two high-pressure), a modular common rail system for precise injection, and an EPA Tier 4/IMO III compliant exhaust aftertreatment system. The engine is in active production since around 2008, with two generations of fuel systems: HPI and MCRS. Common maintenance areas include inspection for turbine shell cracks and impeller damage, exhaust camshaft bolts, abnormal smoke emissions related to fuel quality or combustion imbalance, aftercooler clogging from seawater use, and critical fuel quality for the common rail injection system. Regular servicing is essential to ensure optimal performance and longevity.
