12V396TC82 MTU marine engine from the 396 series

The 12V396TC82 is a proven high-speed diesel engine that has earned a strong reputation for dependable propulsion and auxiliary power at sea. While it belongs to the MTU 396 series, what sets the 12V396TC82 apart is its balanced mix of compact V‑12 engineering, robust turbocharging, and practical serviceability that fleet operators value in daily operation. Shipowners and technical managers choose the 12V396TC82 because it delivers reliable power density and stable performance across a wide range of marine and stationary duties without compromising on fuel efficiency or maintainability.

12V396TC82 technical characteristics and performance data

As a 12‑cylinder V‑configuration four‑stroke diesel engine, the 12V396TC82 is designed for consistent output in demanding environments. The “TC” designation signifies turbocharging and charge‑air cooling, enabling high specific power while maintaining conservative thermal loading. Depending on configuration and rating, typical propulsion and genset outputs for the 12V396TC82 fall in the medium- to high‑speed segment, with commonly applied continuous and intermittent ratings in the roughly 800–1,500 kW class. In marine propulsion, operators typically run the engine in the 1,600–1,950 rpm band; for auxiliary and emergency generator applications, standardized 1,500/1,800 rpm ratings support 50/60 Hz requirements.

Core engineering focuses on durability and ease of overhaul. The compact block and individual cylinder heads facilitate in‑situ maintenance. Turbocharged induction combined with charge‑air cooling stabilizes combustion temperatures and supports clean, efficient operation on marine distillate fuels. A robust lubrication system with high‑capacity oil filtration supports long running intervals, while jacket‑water and separate charge‑air cooling circuits manage thermal loads in warm ambient conditions typical for engine rooms. Mechanical fuel injection with proven governor solutions provides predictable behavior under load steps—an important benefit for harbor maneuvering, DP operations, and sudden electrical load acceptance on gensets.

The 12V396TC82 is favored because it brings an optimal ratio of displacement to footprint, making installation straightforward in refits and newbuilds. Long global service experience within the MTU 396 family means well-understood life-cycle behavior, standardized maintenance tasks, and a broad base of trained personnel. For technical purchasers, this translates into clear planning for service intervals, parts provisioning, and predictable total cost of ownership.
