BV9M628 marine engine for demanding propulsion and power generation

The BV9M628 is a robust, medium-speed diesel engine that has earned a solid reputation for dependable output in continuous-duty operation. Developed within the 628 series ecosystem by MWM & Deutz, the BV9M628 focuses on high mechanical efficiency, durable design, and service-friendly architecture. While the series context matters for lifecycle support and parts standardization, the spotlight here is the BV9M628 itself: a nine-cylinder workhorse designed to deliver consistent torque, controlled emissions with appropriate aftertreatment, and long operating intervals between overhauls.

In marine propulsion and auxiliary power applications alike, the BV9M628 combines proven combustion technology with charge-air optimization and a rugged crankcase. The result is stable performance across a broad speed window and economical fuel consumption in variable-load profiles—key criteria for shipowners, fleet managers, and power plant operators.

BV9M628 technical characteristics and performance data

The BV9M628 is a turbocharged, four-stroke diesel engine with charge-air cooling. Its nine-cylinder configuration balances compactness with smooth running and strong low-end torque. Depending on build and rating, the BV9M628 diesel engine typically operates in the medium-speed range, supporting both propulsion and generator drive duties.

Typical technical parameters (subject to configuration and class requirements):

Configuration: 9 cylinders, turbocharged with intercooling; medium-speed, four-stroke.
Speed range: approximately 500–900 rpm for marine and stationary ratings.
Power output: commonly in the multi-megawatt class, with continuous (MCR) ratings tailored to propulsion or genset duty.
Displacement: large-bore design with per-cylinder displacement in the high-litre class, yielding substantial total swept volume.
Fuel types: MGO/MDO operation; heavy-fuel capability available depending on equipment package and operating profile.
Emissions: compliance pathways to IMO and inland standards via combustion tuning and external aftertreatment (e.g., SCR).

The BV9M628 by MWM & Deutz is valued for its mechanical robustness and maintainability. A stiff, high-strength block, replaceable wet liners, and modular cylinder heads simplify overhauls. Optimized charge-air routing enhances thermal efficiency, while durable injection equipment supports stable atomization at varying loads. For operators, this translates into reliable specific fuel oil consumption and predictable lifecycle costs.
