In 1980', our company adopted the comet V combustion system and diesel design ·technique of Ricardo Consulting Engineers Company and have make great improvement in de- sign. Thus, the power, economy and tiability reached a advanced level among the same kind products all over the world. HUAFENGDONGLI brand 495 series diesel engine was prized by the National Sci- ence Congress and its easy to adapt. According to the different application, some parts are changed accordingly.
