Unleashing Fuel Efficiency Piezoelectric Injectors Ignite Innovation

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. Considering the nonlinearity of a piezoelectric actuator, the complete electro-mechanical-hydraulic model of the piezoelectric injector was established and ... (3) Faster Acceleration: Piezo devices can react in a matter of microseconds. Acceleration rates of more than 10,000 g (response times of 0.01 ... Simplified operation: The internal construction of the Piezo injector varies with the Electromagnetic type. · The fuel rail pressure / injector operating ... Piezoelectric stack actuators are particularly useful because they can generate large forces, but the displacement is almost linear depending on ... Piezoelectric actuators are increasingly used in fuel injectors due to their quick response, high efficiency, accuracy, and excellent ... Accordingly, a PICMA® stack actuator with a layer thickness of 60 µm has an approx. 70 times higher capacitance than a PICA stack actuator of the same volume ... The major advantage of piezoelectric injectors is their speed of operation and the repeatability of the movement of the valve. The dilation and retraction ... The operation of piezoelectric injectors is quite similar to that of solenoid injectors, with the difference that they have a ceramic core. This is ... Piezoelectric transducers and actuators are uniquely able to combine speed, force and precise motion into a compact package.
