Description

The D series engine is a new generation diesel engine meticulously crafted by SDEC using advanced European and American engine technology, in conjunction with AVL and SWRI (Southwest Research Institute), and in accordance with North American heavy-duty diesel engine standards. It is an outstanding representative of the techno – logically advanced mature models with similar displacement in China, and the social inventory of this series of products exceeds 1 million units. This series (D683) marine diesel engine is developed based on the needs of high-speed boats in China. It has advantages such as compact structure, strong power, good economy, and low vibration and noise. It can meet various application in high-speed patrol boats, yachts, traffic boats, work boats, as well as ships such as passenger ships and ferries, as well as the 100-150KW marine generator set market.
