| Abstract: | On the base of the PMS type pump, which is produced by Weifu group company and powerful in in-line pumps, under high injection pressure the influences of three kinds of basic delivery valves on the comprehensive performance, such as pump pressure, nozzle pressure, residual pressure, injection rate, secondary injection and cavitation, are investigated. The results show that the constant pressure delivery valve has obvious advantages in the residual pressure controlling, injection time stability, avoiding secondary injection and cavitation compared with damping valve and constant volume delivery valve. |
| Keywords: | diesel engine delivery valve injection pressure injection rate secondary injection cavitation |
