| Abstract: | In order to analyze the characteristics of the electronically-controlled gas injector for the LPG/gasoline dual fuel vehicle,one kind of test dais for the electronically-controlled gas injector was exploited.And making use of this test dais,static injection ratio,dynamic injection quantity,stability and different battery voltages and fuel pressures working on flow characteristics of one low resistance injector were tested and the test data was analyzed and verified.Results show that the designed platform functions well and reliably.It could realize the calibration for the electronically-controlled gas injector. |
