Piezo Injectors

Piezo injectors are part of the injection system of common rail diesel engines, such as those offered by SEAT in numerous models. Piezo injectors are equipped with a ceramic element whose structure changes when subjected to electrical voltage and so actuates the injection needle. Compared to solenoid injectors, its advantages lie in the faster control of the injection process and more precise control of the injection quantity. This makes for better combustion and thus has a positive effect on performance, fuel consumption and the noise produced by the engine.
