How Bosch Piezoelectric Diesel Injector Works

Common rail Diesel fuel injection is now the state of the art in engine injection. The Bosch Piezoelectric (crystal) injector operates using a crystal stack, usually Quartz, that changes size when energized. The piezoelectric effect states that when a crystal such a Quarts is squeezed an electric current is generated. By the same token, when electricity is applied to the crystal is changes shape. This minute change in crystal size is used to trigger a small fuel chamber on and off. In turn, this chamber creates a pressure differential at the top of the injector which make it open and close. See how it all works here.

this system is not good for marine aplications.

Excellent! But I am embarrassed by the driver control in the next movie. In the description of the injector is written that you can not change the polarity .... This will lead to malfunction ... What do you mean?

I love that game!

All the video's are greta, but the voice is awfull, sound's like google translate.
