As introduced by Lin Zhiqiang, since "the 11th Five-Year Plan" period, the Yuchai marine electric engines business has developed quickly and the annual production and sales volume increased from 2,500 in 2005 to 21,200 in 2011, becoming an important production enterprise in the marine electric field. During this period, Yuchai has made substantial investment in R & D, especially in R & D in heavy engines, and has filled the gap in heavy high-speed marine electric engines. 

The released 12VC, 12VT and 8C engines have integrated numerous international advanced technologies, featuring energy conservation, and high efficiency, being reliable and durable, light and environmental friendly and compact appearance, etc. Among them, 12VT is the 12-cylinder engine with the 6T-based V-type arrangement. With the output volume of 32.7L and power range between 680-880kW, it is the ideal motor for above-18-meter vessels used for officials, yachts and 600-800kW land engines; 8C is the straight 8-cylinder engine developed based on 6C engines which are put into operation by batch this year. With the output volume of 52.8L and power range between 800-1,100kW, it is used for 5,000 to 7,000-ton transport ships, 40-60-meter dory trawlers, light fishing vessels, 800-1,000kW land power units and 600-800kW commercial auxiliary engines. 12 VC is a 12-cylinder engine which is also developed based on 6C platform and adopts V-type design. With the output volume of 79.13L and power range between 1,320-1,650kW, it is the ideal power used for 7,000-8,000-ton transport ships, passenger ships, engineering ships and 1,200-1,500kW land power units.
