Marine Diesel Engines

We boast extensive experience as a top-tier builder of marine diesel engines in the global market, and our integrated service system extends from new model design and production to sales and after-sales services. These valuable assets enable us to meet increasingly diversified customer needs and provide engines that satisfy ever-stricter environmental regulations.

Low Speed Diesel Engines

HSD Engine is the leading player in low speed diesel/gas power plants. Aggregate production reached the 100 million bhp milestone, evidence of our extensive performance record and experience. We have achieved several milestones in the industry to include the world’s first large electronically-controlled marine engine in 2003, and the world’s largest marine engine to date in 2005. In 2013, we became the first engine builder to commercialize a Dual-Fuel low speed engine.

  • Low Speed Diesel/Gas Power Plants
  • HSD Engine has entered into a technical alliance with WinGD in Switzerland in 1984 and has pursued R & D to develop next-generation engines and meet environmental regulations.
