How do Piezoelectric injectors work?

Piezoelectric injectors use piezoelectric materials that change shape when an electric voltage is applied, enabling precise control over fuel injection timing and quantity. When activated, the piezoelectric element expands or contracts, opening a nozzle to spray fuel into the combustion chamber. This technology allows for faster response times and finer atomization of fuel compared to traditional electromagnetic injectors, enhancing engine efficiency and performance. Overall, piezoelectric injectors contribute to improved fuel economy and reduced emissions.
