Precision Meets Velocity Piezoelectric Injectors Outpace Competitors

High accuracy · Quick response · High keeping suspension · Low consumption · Electromagnetic noiseless · High-density mounting is possible by small size · Simple ... Compared to conventional electromagnetic injectors, the piezo injector is four to five times faster. Because the fuel injector's opening or ... Frequencies in the kilohertz range are desirable and piezo actuators provide faster response than electromagnetic drives, such as solenoids or voice coils. The ... The different parts of the proposed model are then depicted (injector holder, control valve, nozzle and piezoelectric valve) and merged. Finally, a comparison ... While direct actuator's stroke is generally lower than 100 μm, amplified piezo actuators can reach millimeter strokes. ... piezoelectric fuel injectors ... Piezo actuators have response times on the order of just a few tenths of a millisecond. The piezo-electric technology was commercialized in common rail ... Piezoelectric actuators can give the same performance from a smaller component, produce higher-resolution movement, and require a lower operating voltage than ... ... 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 correct answer is A, piezo, which allows for precise fuel metering leading to better fuel economy and reduced emissions. Piezo injectors ... use in diesel fuel injectors. Sept 2009 – Milestone: Measure and compare piezoelectric and mechanical reliabilities of tape- cast and hot ...
