Unleashing the Speed Demon Piezoelectric Injectors' Unstoppable Power

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 ... Simplified operation: The internal construction of the Piezo injector varies with the Electromagnetic type. · The fuel rail pressure / injector operating ... 46. What explains why EHIs with Piezo actuators respond faster to energization signals from the injector drivers? vantages with respect to electromagnetic types. In particular, they provide for extremely fast response (e.g. less than. 100µs) and permit proportional ... Hence, unlike the electromagnetic actuators which produce forces from a distance onto a mechanical load, piezoelectric actuators exploit the strains and ... Such precise control of high-pressure fluid is made possible by using piezoelectric actuators controlling small valves within fuel injectors. ... injection rate is simpler than commercial fuel injectors based on electromagnetic actuators. In order to better prove the latter concept, a more engineered ... I think they are getting better. We used them maybe 4 years ago. So the new technology may be better. 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 the ... The expansion can be precisely repeated much better than using electro-magnetic solenoid style injectors. This allows for better fuel metering ...
