4L4TNV86-GS-50Hz

The Yanmar 4L4TNV86‑GS‑50Hz is a compact 4‑cylinder inline diesel engine coupled to an alternator, delivering approx. 46 kW (58 kVA) of electrical power for shipboard auxiliary use; source-listed power 48.0 kW. The supplied category identifies it as Auxiliary Engine (Generator Set), and it is normally installed in the engine room as a generator prime mover or other ship-service auxiliary engine. In that role, its primary purpose is to provide mechanical power for electrical generation or another auxiliary shipboard duty. Generator-set versions are integrated with an alternator and electrical protection, while standalone auxiliary engines may drive other machinery; both use the same core diesel support systems. Within the supplied list, this entry is distinguished from neighbouring variants by its model designation and the explicitly listed power; no further model-specific difference is stated in the source. No additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

Common failures & inspection points

Fuel-injection or combustion faults cause smoke, unstable speed, poor load acceptance or high exhaust temperature
Lubrication or bearing problems cause low oil pressure, metal debris, rising temperature or shutdown
Cooling-system restriction or leakage causes high coolant temperature and repeated thermal alarms
Turbocharger or charge-air fouling causes smoke, slow load response and elevated exhaust temperature
Governor, speed-sensor, starter or control faults cause difficult starting, frequency instability or failed automatic operation

Service & Maintenance

Inspect fuel, lubrication, cooling, intake, exhaust, turbocharging, starting, governor and shutdown systems. Trend oil pressure, coolant and exhaust temperatures, speed stability and load response. On generator sets, also review alternator and breaker behaviour. Refer to the manufacturer documentation for the exact figure for clearances, pressures, temperatures and service limits.
