The most important next-generation common rail system fuel injection system, the transformation is shown in Figure 15 using a piezoelectric fuel injection valve (Piezo-injector valve). The fuel injection valve is controlled by the piezoelectric effect. Piezoelectric effect is caused when the ionic crystal (electrical disabilities Note quartz, potassium sodium tartrate) deformation, it will create a potential breeding. Can in turn use the piezoelectric effect, that is coupled with voltage transistors will be stretched.

Use of piezoelectric fuel injection valve interest is: what travel can each produce multiple triggering breeding cycle; Spring King more than a short time to switch between fuel injection valve; can have a great ability to nurture a total resistance rail pressure; fuel can be accurately controlled pressure relief valve trip; trigger voltage is 110 ~ 148V, depending on the orbital pressure.

To note are: maintenance, fuel injection valve would help if swap, you must hold the fuel injection valve and injection system using matched, while still holding comparable amount of fuel injection (IMA) experiments.
