Next-Gen Actuators Piezoelectric Injectors Outpace Electromagnetics

Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of a fuel injector. 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 ... According to Bosch, which introduced piezo injectors to the industry, a piezo actuator acts up to five times faster than a standard injector solenoid and ... ... faster-acting hydraulic forces. ... Technician B says that control valves that use piezoelectric control valves are the only actuators capable of ... The operation of piezoelectric injectors is quite similar to that of solenoid injectors, with the difference that they have a ceramic core. This is ... The major advantage of piezoelectric injectors is their speed of operation and the repeatability of the movement of the valve. The dilation and retraction ... Piezoelectric actuators can give the same performance from a smaller component, produce higher-resolution movement, and require a lower operating voltage than ... A second actuator type, using piezoelectric material to provide displacement, can provide faster response than a solenoid actuator. However, a piezoelectric ... (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 ... ... 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 ...
