Speed and Accuracy United Piezoelectric Injectors Transform Fuel Injection

One type of fuel injector that offers precise metering of fuel is the piezoelectric fuel injector. Piezoelectric fuel injectors employ piezoelectric actuators ... ... actuators and key working units, and then changing the control settings. 2. Methods 2.1. Test object The tests were carried out on the Siemens VDO ... The ECU then controls various output actuators like fuel injectors. ... • 5 times faster than conventional injectors. 7. Emission Control ... The method of testing then is to measure the resistance of the injector at 100v. ... injectors have solenoid actuators and not piezo actuators. The expansion can be precisely repeated much better than using electro-magnetic solenoid style injectors. This allows for better fuel metering ... ... faster than electromagnetic injectors and allow up to 5 injections per cycle. Diagnosing faulty piezoelectric injectors requires resistance, capacitance ... Super fast response · High precision displacement · Low power consumption · Electromagnetic (noiseless) · Long life (has been installed in automobiles) ... These piezo motors have many applications within the medical field They are now being used more than electromagnetic motors due to the high number of advantages ... ... injectors: The pump injector ... faster than with electromagnetic valves. This ... piezoelectric valve in the pump injector are: – The piezoelectric actuator. Considering the nonlinearity of a piezoelectric actuator, the complete electro-mechanical-hydraulic model of the piezoelectric injector was established and ...
