The natural gas engine was successfully developed by CSIC 711 for three years. The project team has broken through a series of bottlenecks and key technologies that restrict the development of high-performance natural gas engines in China, such as high-efficiency lean combustion and air-fuel ratio control, safety protection control, heat load of heated parts, etc., and formed a self-designed and developed high-power marine medium-speed natural gas engine. Ability. The successfully developed engine can meet IMO Tier III emission standards and its technical indicators have reached the international advanced level. It is worth mentioning that the engine is designed according to the intrinsic safety requirements of the ship's regulations, with high safety and reliability, and is welcomed by ship owners and design institutes.

It is reported that the advent of the engine will further increase the competitive strength of domestic natural gas engines, meet the market demand of China's coastal high-power marine natural gas engines, and effectively promote energy-saving and emission reduction work in the ship power field.

In the next step, the project team will continue to develop natural gas engine performance and reliability tests. The classification society certification work and engineering development will also be carried out simultaneously, preparing for the early introduction of 8M23G natural gas engine products into the market.
