Recently, Yuchai Huayuan Machinery (Yulin) Co., Ltd. was awarded the third prize of Guangxi for progress in science and technology to commend its innovation in the science and technology field and contributions to industrial scientific and technological progress.

Huayuan replaced gravimetric method with particle counting method for the first time in the industry during testing the diesel engine filters manufactured by it, and conducted scientific calibration of the filtration efficiency indicator of filters to make them meet the use requirements of engines above National II and III standards. At the same time, Huayuan first extended additional functions such as hand pump, liquid level sensor, heater and temperature switch to filters, to effectively reduce the failure rates of parts like fuel injection pump, fuel injector and common rail pipe. Huayuan has smoothly transformed scientific and technological achievements and accomplished matching of Yuchai engines and parts supply in customer services.
