  • Use of in-house technology in product development has elevated fundamental competitiveness.
  • The new-concept system can be customized, setting it apart from competing models.

HSD Engine has applied in-house technologies to complete the development of DelNOx® SCR, which provides for cleaner engine operation for better air quality around the world.

The International Maritime Organization (IMO) continues to tighten exhaust emission standards, and shipowners are demanding marine engines that are ever-more eco-friendly. Thus the inevitable need for greener systems is sweeping the shipbuilding and marine shipping industries. HSD Engine has responded by coming up with the ideal solution: a new-concept de-NOx system based on Selective Catalytic Reduction at low temperature.

HSD Engine officials regularly visit customers to hear what they have to say, and the company’s R&D team has continued to work on technological breakthroughs. These efforts have paid off with the completion of the world’s first low-temperature de-NOx system for use onboard ships, and the system has been certified by major ship classification societies. The system can also be customized for easier installation.

HSD Engine has applied proprietary technologies in developing the eco-friendlier de-NOx system, diversifying the business portfolio and laying the groundwork for an influx of orders for new engines that are in step with the environmental trends of the industry.
