HM10C Marine Engine

The HM10C Marine Engine is designed to deliver reliable power and consistent performance for marine propulsion applications. Featuring a six-cylinder, inline, water-cooled, four-stroke, direct-injection diesel configuration, the engine combines robust construction with a turbocharged and intercooled intake system to support efficient combustion and dependable operation in demanding marine environments.

With a 9.726-litre displacement, a 17:1 compression ratio, and rated power outputs of 205 kW, 230 kW, and 240 kW, the HM10C offers flexible operating options at rated speeds of 1,500, 1,800, and 2,100 rpm, respectively. Its electric starting system, dry cylinder liners, and two-valve-per-cylinder design support practical operation and maintenance, while the specified fuel consumption of 195 g/kWh provides a benchmark for evaluating operating efficiency.

Designed with a six-cylinder inline layout and a firing order of 1-5-3-6-2-4, the HM10C combines dependable power delivery with a practical marine engine configuration. With IMO Tier II emissions classification, an SAE No. 1 flywheel, and a compact overall design, the HM10C Marine Engine is a suitable power solution for marine applications requiring reliable propulsion performance.
