Main Engine 4-Stroke · Main Engines (4-Stroke)
The Hanshin 8LLH28G is an eight‑cylinder, inline 4‑stroke trunk piston main engine delivering 2 880 kW at 700 rpm, designed for medium‑speed propulsion with flexible HFO/MDO fuel capability; source-listed power 2880.0 kW. The supplied category identifies it as Main Engine (4-Stroke Trunk Piston), and it is normally installed in the main engine room as a propulsion prime mover connected directly or through reduction gearing to the propeller or propulsion system. In that role, its primary purpose is to convert fuel energy into mechanical propulsion power using a trunk-piston four-stroke cycle. Compared with a two-stroke crosshead engine, a four-stroke trunk-piston engine combines piston and connecting-rod motion directly at the crankshaft and typically operates at higher rotational speed. 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.
Every value below comes from the manufacturer datasheet or class-society record on file for this model.

What our service work and the manufacturer documentation say about keeping this model running.
Trend oil pressure, coolant temperature, exhaust temperatures, load balance, vibration and crankcase condition. Inspect fuel equipment, filters, coolers, valves, turbocharger, mounts and safety shutdowns according to the maintenance plan. Investigate persistent cylinder imbalance, oil debris or coolant leakage promptly. Refer to the manufacturer documentation for the exact figure for valve, bearing, injection and wear limits.
Carry fuel and oil filters, injector service parts, valve-train and gasket items, cooling-system seals, sensors, belts where fitted and critical bearing or turbocharger consumables.
