Auxiliary Engine (Generator Set) · Auxiliary Engines
Marine engineers and operators rely on reliable auxiliary engines to ensure the smooth operation of their vessels, especially in critical situations where constant power supply is essential. Discovery Energy’s KKHXN2.48DIM engine, designed for constant speed auxiliary applications, delivers 30 kW of power at 1800 RPM, meeting the rigorous requirements of Category 1 IMO standards. With a naturally aspirated, four-stroke compression ignition engine featuring direct injection, this unit provides robust performance. Common issues such as fuel-injection deterioration, lubricating oil contamination, cooling system fouling, and charge-air restriction can lead to operational issues like uneven firing, increased exhaust temperature, or loss of power. Regular maintenance, including inspections and the use of spare parts such as fuel-system service items, lubricating-oil and fuel filters, and valve-train consumables, is crucial for sustaining optimal performance. Service notes emphasize the importance of monitoring key indicators like oil pressure, coolant temperature, and exhaust temperatures, and conducting thorough inspections of critical components to ensure the engine remains in top condition.

What our service work and the manufacturer documentation say about keeping this model running.
Review operating trends for lubricating-oil pressure, coolant temperature, exhaust temperatures, load balance, crankcase condition and abnormal vibration or noise. Inspect filters, coolers, fuel equipment, valve gear, turbocharging equipment, mounts, flexible connections and safety shutdown devices in accordance with the installed configuration. Check for fuel, oil, coolant and exhaust leakage and verify that protective alarms and shutdowns are functional. A surveyor will normally look for evidence of disciplined maintenance, clean machinery spaces, leak control, intact guards and reliable safety functions. Use the engine serial number and manufacturer documentation for all exact wear limits, adjustment values and overhaul criteria.
Useful onboard spares typically include fuel-system service items, lubricating-oil and fuel filters, cooling-system seals, belts where fitted, valve-train consumables, injector-related service parts, sensors and common gaskets or O-rings. Critical spares should be selected against the exact engine serial number, installed emissions package and vessel redundancy; refer to the manufacturer parts documentation before ordering.
