Deals with the operation of the fuel pressure limiter or regulator. Also explains safety issues in dealing with newer piezoelectric Diesel injection systems. 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 further information here. Presented using advanced software CG animation technology to help you understand. Part of our Diesel and electronic series shown here on this channel. Enjoy...

It is a microcontroller-based project that uses PIC16F690 which is a 20-pin flash-based and an 8-bit CMOS microcontroller with nano-watt technology. The project prototype has analog inputs namely rain sensor and light sensor that are both activated during automatic mode. Push button switches for retrieval and exposure are activated during manual mode. It has also limit switches with shared input to cause the motor to stop after retrieving or exposing hanged clothes and toggle switch input that serves as a selector for manual or automatic mode. Analog signals are receive by the rain and light sensor and are converted to digital signals by the microcontroller during automatic mode while digital signals are receive by the microcontroller during manual mode. The rain sensor will detect rain droplets that will give signal to the microcontroller to retrieve the laundry and expose the laundry back as the rain stops while the light detector will also give the signal to the microcontroller to retrieve the laundry at night and expose the laundry at day. The manual mode will give the option to expose or retrieve the laundry manually. The output comprises with a low power-high torque dc motor which is driven by a motor driver. The motor driver is responsible for the forward and reverse rotation of the motor. The motor needs to be supplied with 12-volts direct current while the microcontroller, the rain sensor, light sensor, limit switches and selector require 5-volts direct current ...

This video covers the basics of diodes, bridge rectifiers, and how to build simple unregulated AC to DC power supplies than can handle a few mA up to several Amps. I recommend watching my transformer tutorial first if you are confused about where I am getting the AC voltages from: www.youtube.com This is a followup video on how to make a regulated voltage supply: www.youtube.com Don't forget to subscribe!
