Auxiliary Engine (Generator Set) · Auxiliary Engines
The D13 (EPA family LVPXN12.8LKA) engine operates on a 6-cylinder, 4-stroke compression ignition cycle, designed for both constant speed propulsion and auxiliary applications. Developed by AB Volvo Penta, this model is categorized under IMO Category 1 engines, featuring direct injection with turbocharging. The power output of 588 kW is consistent across various test configurations, including a constant speed propulsion cycle at 1900 RPM and an 8-mode variable speed auxiliary cycle also running at 1900 RPM. Common failures include issues like fuel-injection deterioration or contamination, lubricating-oil problems, cooling-system fouling, and valve-train wear. For maintenance, critical spares should be selected based on the exact engine serial number and installed emissions package. Regular checks of lubricating oil pressure, coolant temperature, and exhaust temperatures are essential to ensure reliable operation.

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.
