How Piezo Injectors Work. The heart of a Piezo (short for piezoelectric) injector is the piezo crystal. When electricity is applied to the crystal, it rapidly expands, thus making it suitable to act as the actuator in a diesel fuel injector.ressurized fuel is delivered to the top of this needle as well, the force of which keeps the needle closed. When the piezo crystal is energized, a valve at the top of the needle opens, allowing the pressurized fuel at the top of the needle to return to the tank through the return line.
ITT Controls wants to meet the demand for different components and alternatives in the oil and gas industry. Piezo ignition is a type of ignition that is used in portable camping stoves, gas grills and some lighters and guns.It consists of a small, spring loaded hammer which, when a key is pressed, a single crystal of PZT or quartz crystal touches. Piezoelectric quartz, which means that a voltage is produced when deformed.iezo ignition systems can be operated by a lever or pushbutton or integrated regulator. An electric spark is generated by rotating the knob or pressing the button. Lighters with piezo-electric ignition do not usually work at great heights or have difficulty in igniting as the percussion is misaligned.
