World's First 7X82DF Double-Fuel Main Engine Delivered to Its Buyer

The world's first 7X82DF double-fuel main engine was delivered at China Shipbuilding Industry Corporation Diesel Engine Co., Ltd, a subsidiary of China State Shipbuilding Corporation Limited (CSSC), on April 28.

With a maximum continuous power of 22,500 kilowatts and a weight of 928 metric tons, the main engine meets the Tier III emission standards of the International Maritime Organization and is to be installed on a 318,000-ton oil tanker that built by CSSC's Dalian Shipbuilding Industry Co., Ltd.

The 7X82DF double-fuel main engine was developed by CSSC's Winterthur Gas & Diesel Ltd.

Integrating advantages of super-large power, smart control capacity and environmental-friendly design, the engine takes the lead among units of its kind in the world.

Compared to conventional engines of the same kind, the 7X82DF double-fuel main engine releases 25 to 30 percent less carbon dioxide, and 85 percent less oxynitride. What's more, it has very limited particulate matter emission and no sulfide emission.
