Fuel Injection Mastery Piezoelectric Injectors' Unmatched Response Times

... faster-acting hydraulic forces. ... Technician B says that control valves that use piezoelectric control valves are the only actuators capable of ... Piezo actuators (not to be confused with piezo motors) provide motion output proportional to a drive voltage – usually up to one millimeter and high dynamics ... The expansion can be precisely repeated much better than using electro-magnetic solenoid style injectors. This allows for better fuel metering ... The maximum expansion of the Siemens actuator is 40 µm. The control on the injector is quicker allowing more precision in the fuel injected volume, and a. Both types work well, but piezo injectors offer finer control of the injection cycle, and generally produce less engine noise than their ... 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 ... But solenoid injectors tend to vibrate more than piezo units, creating more noise. In a piezo injector, the electronic engine management system ... Piezoelectric transducers and actuators are uniquely able to combine speed, force and precise motion into a compact package. High accuracy · Quick response · High keeping suspension · Low consumption · Electromagnetic noiseless · High-density mounting is possible by small size · Simple ... ... piezoelectric and electromagnetic injectors. However, before ranges ... The better ones have it in the range of less than 0.1Ω. In ...
