Auxiliary Engine (Generator Set) · Auxiliary Engines
This engine is commonly found in shipboard applications where constant speed propulsion with controllable pitch propellers or variable speed propulsion with fixed pitch propellers is required. The KMRBN26.4COM engine operates within a power output range of 1215 kW at speeds between 1800 and 2300 RPM, ensuring reliable performance across various duty cycles. Its specifications include a 4-stroke compression ignition cycle and a direct injection common rail fuel system, complemented by turbocharging for enhanced performance. The engine is designed to meet IMO Category 1 standards and is suitable for both propulsion and auxiliary applications, including propeller law systems. Regular maintenance is crucial, focusing on lubricating oil pressure, coolant temperature, exhaust temperatures, and load balance monitoring. Common issues can arise from fuel-injection deterioration, lubricating oil contamination, cooling system fouling, charge-air restriction, and valve-train wear. Critical spare parts should be kept on board, including fuel system components, oil and fuel filters, cooling system seals, and valve train consumables, all of which are specific to the exact engine serial number and installed configuration.

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.
