Explanation. Piezo injectors use piezoelectric technology to open and close fuel injectors at extremely high speeds and precision to inject fuel into an internal combustion engine. These injectors are used in both petrol and diesel engines to improve their persformance and efficiency.iezo injectors have the ability to inject fuel into the cylinder several times in one stroke (as many as seven times). This is very useful in a diesel engine where a spark is not used to ignite the fuel. Multiple injections allow a pre, main and post explosion and ensures no fuel is wasted.
