CW200 Marine Diesel Engine
Weichai CW200 diesel engine series is the medium-speed engine with independent intellectual property rights designed and developed by Weichai on the basis of introduction of MAN20/27 diesel engine series. It is divided into in-line 6-cylinder, 8-cylinder and V-type 12 cylinder models. The series uses four-stroke, direct-injection, fresh water closed cycle, seawater open circulation cooling, turbocharging, and intercooling.
The CW200 series is mature in technology, featuring low fuel consumption, light weight, high reliability and low emission, and has been optimized for product design according to different market demands. It is suitable for all types of ships and power generation equipment.
