Abstract

It has been established that the average values of the error in measuring the flow rate of the test liquid (TL) by electromagnetic injectors (EMI) are associated with the vehicle mileage. The greater the mileage, the higher the value of the error. It is shown that the dependence of the error in measuring the flow rate on the run can be described in a rough approximation by regression. The technical condition of the EMI was assessed by an instrument for cleaning and analyzing fuel injectors HP-6V, complete with an Ultrasonic Cleaner ultrasonic bath. The objects of study are the EMI of gasoline engines with distributed fuel injection. The injectors were used in the power units of GAZ-27040 V (“Gazelle”), ZAZ Chance SX, VAZ 2121 (“Niva”), Chevrolet Lacetti and others, mileage from 0 to 188 thousand km. Siemens DEKA ZMZ 6354, Siemens DEKA VAZ 6238, Siemens DEKA VAZ 20734, Siemens DEKA VAZ 20735, Bosch 0 280 158 502, Bosch 0 280 158 017, Bosch 0 280 158 022, Bosch 0 280 150 9925, Denso 23925 injectors tested.
