Igniting Efficiency Piezoelectric Injectors Dominate Fuel Delivery

But solenoid injectors tend to vibrate more than piezo units, creating more noise. In a piezo injector, the electronic engine management system ... a high voltage to open the injector; · The first injection event is called the Pilot Injection, during which time, a small amount of fuel is delivered to better ... Piezoelectric injectors operate faster than their solenoid driven counterparts, which permits more injections per stroke, higher fuel pressures, and ... The piezoelectric element represents the latest generation of injector actuators and ensures higher performance, in particular faster response, than the ... The requirements for diesel engine injection systems are constantly increasing: higher pressures, faster switching times and the flexible adaptation of the ... Simplified operation: The internal construction of the Piezo injector varies with the Electromagnetic type. · The fuel rail pressure / injector operating ... This chapter is dedicated to modeling, system identification, and control of electromagnetic actuators with the main focus on the actuators used in magnetic ... Aerospace and Defense: The high precision and fast response times of piezo actuators make them valuable in aerospace applications like fuel injectors, active ... The high precision of individual actuators makes them the most sus- ceptible to damage components of common rail systems in difficult operating ... Piezoelectric transducers have replaced the electromagnetic actuator ... lower than those found in a diesel engine, the piezoelectric actuators act directly on ...
