Auxiliary Engine (Generator Set) · Auxiliary Engines
Marine engineers and operators rely on reliable auxiliary engines to ensure the smooth operation of vessels, providing essential power for auxiliary systems. FPT Industrial’s CFPXN06.7DGS engine, produced in 2012, is designed for constant-speed auxiliary applications and is rated at 208 kW at 1800 rpm with a maximum torque of 1102 Nm. This mechanical direct injection, turbocharged, four-stroke engine is compliant with IMO Category 1 regulations. Common issues include starting failure, unstable speed, poor combustion, lubricating-oil system faults, cooling-system malfunctions, and electrical or control-interface faults. To maintain reliable operation, it is crucial to keep a range of spare parts on board, including fuel and lubricating-oil filters, air-filter elements, injector spares, seals, gaskets, pump service kits, and starting-system components. For generator sets, additional governor and speed-control components, sensors, relays, and electrical interface spares should be available. Regular maintenance checks should focus on starting reliability, load acceptance, speed stability, exhaust temperatures, oil pressure, cooling temperatures, and abnormal vibrations. Inspection of the fuel, oil, cooling-water, and exhaust systems for leakage, and verification of filters, coolers, pumps, and ventilation condition, are also critical.

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.
