| Abstract: | Analysis and test for injection quantity equality of the electronic controlled injector are carried out according to the requirements of injection for high pressure common rail system. The emphasis is placed on the key effective factors of injection quantity equality of injector. Influences of machining accuracy of injection hole, drive circuit, common rail pressure on injection quantity equality are analyzed. The tests of injection quantity equality corrected with various pulse width increments are carried out. The result shows that after correction the injection quantity equality can achieve the requirements of 3 % to 5 %. |
