Igniting Efficiency Piezoelectric Injectors Empower Lean Combustion

... faster than electromagnetic injectors and allow up to 5 injections per cycle. Diagnosing faulty piezoelectric injectors requires resistance, capacitance ... However, some piezoelectric materials for sensors or actuators are adopted in elevated temperature environments, such as in applications for ... (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 ... Consequently, it features much lower current consumption than that of an electromagnetic buzzer. The current consumption (excluding that of the peripheral ... 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 transducers and actuators are uniquely able to combine speed, force and precise motion into a compact package. Hence, unlike the electromagnetic actuators which produce forces from a distance onto a mechanical load, piezoelectric actuators exploit the strains and ... Piezoelectric stack actuators are particularly useful because they can generate large forces, but the displacement is almost linear depending on ... While direct actuator's stroke is generally lower than 100 μm, amplified piezo actuators can reach millimeter strokes. ... piezoelectric fuel injectors ... The high precision of individual actuators makes them the most sus- ceptible to damage components of common rail systems in difficult operating ...
