Auxiliary Engine (Generator Set) · Auxiliary Engines
This maritime equipment category includes auxiliary engines. The Caterpillar C15 (EPA family DCPXN15.2EA3) is a 400 kW auxiliary engine model that was introduced in 2013. Operating on a 6-cylinder, 4-stroke combustion cycle and turbocharged with electronic direct injection, it falls under IMO Category 1 for environmental standards. Common failures include starting issues due to weak batteries or fuel supply faults, unstable speed caused by governor malfunctions, poor combustion from injector wear, lubricating-oil system faults indicated by low pressure alarms, cooling-system derating due to pump failure, and electrical interface problems between the engine and driven equipment. Regular maintenance should focus on ensuring reliability in starting and load acceptance, stability of speed, and checking for leaks in fuel, oil, and exhaust systems.

What our service work and the manufacturer documentation say about keeping this model running.
Check starting reliability, load acceptance, speed stability and the engine's ability to carry its assigned electrical or mechanical load. Trend exhaust temperatures, oil pressure, cooling temperatures and abnormal vibration and compare cylinders or operating points for imbalance. Inspect fuel, oil, cooling-water and exhaust systems for leakage and verify filters, coolers, pumps and ventilation are in serviceable condition. For generator sets, verify governor response, load sharing, generator protection, emergency shutdowns and automatic-start functions where fitted. Inspect foundations, flexible mounts or couplings and the interface with the alternator or driven machine. For cylinder dimensions, rotational speed, pressures, clearances, temperatures, wear limits and setting values, refer to the manufacturer documentation for the exact figure.
Keep fuel and lubricating-oil filters, air-filter elements where fitted, injector-related spares, seals and gaskets, pump service kits and starting-system components on board. For generator duties, carry selected governor or speed-control components, sensors, relays and common electrical interface spares according to the installed control system. The final spare inventory should follow manufacturer recommendations, class requirements and the number of redundant generator or auxiliary sets available.
