Recently, the key project of "key basic parts and general parts" of the "Eleventh Five-Year Plan" national science and technology support program "Technology development and industrialization of high-pressure variable pump" was accepted by the project organization unit.
Through the implementation of the project, the volumetric efficiency, rail pressure and drive torque stability of the key components of the high pressure common rail system of the diesel engine were investigated, and the design, trial production, testing, evaluation, calibration process and quality were improved. The control system has mastered the key technologies for improving the volumetric efficiency, optimizing the cam profile, improving the low-speed efficiency of the fuel pump, improving the structure of the inlet/outlet valve and the oil spill valve, and successfully developing the CB18 and CPN2 on the basis of the introduction, digestion and absorption. .2BL type high pressure variable displacement pump. Among them, the self-developed high-pressure variable pump CB18 is mainly used in common rail systems for cars and light vehicles. It has been technologically innovative and domestically produced by digesting and absorbing foreign advanced technology CPN2.2B L. It is mainly used for heavy-duty diesel common rail systems. The technical level of products reaches the international advanced level. The project has now obtained 5 new patents and applied for 1 invention patent to form a national standard.
At present, the high-pressure variable pumps CB18 and CPN2.2BL have been used in diesel common rail systems produced by Yunnei, Yuchai, Chaochai, Xichai, Weichai, and other companies, and have realized sales revenue of more than 80 million yuan.
