Auxiliary Engine (Generator Set) · Auxiliary Engines
This is a marine auxiliary engine designed for use in vessels requiring variable-pitch and electrically-coupled propulsion systems. The Caterpillar C15 (EPA family FCPXN15.2EB3) engine boasts a powerful output of 403 kW at 2000 rpm, delivering a maximum torque of 2437 Nm. The EPA certified engine, meeting Category 1 IMO standards, operates on a 4-stroke combustion cycle with six cylinders and a displacement per cylinder of 2.53 liters. Fuel is delivered via an electronic direct injection system, and the engine utilizes turbocharging for enhanced performance. Caterpillar recommends regular maintenance to ensure optimal operation, including trending exhaust temperatures, oil pressure, and cooling temperatures. Inspections should also focus on fuel, oil, and cooling systems for leaks and verifying the functionality of filters, coolers, pumps, and ventilation. For generator duties, verify the governor response, load sharing, generator protection, and automatic start functions.

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.
