Electronic Throttle Control

Electronic Throttle Control (ETC) has been widely used in most of the
automobiles around the world. ETC is also known as Drive-By-Wire (DBW).
Since most of us demand for a car which is fuel efficient and meets gas emission,
car manufacturer had been finding ways to built them. The invention of Electronic
Throttle Control was a good way towards reducing the fuel consumption and
exhaust emission. The objective of this project is to build a functional ETC system
and study its control element in the process. The main focus of this project is to
control the opening of the "butterfly" valve. To accomplish this target, a remote
control servomotor will be attached to the Electronic Throttle Body (ETB). The
servomotor then will be control remotely by using PIC microcontroller. Gearing
set and spring is use to help the servomotor achieve high torque and low speed
condition and to maintain the position of the butterfly valve opening. At the end
of the project, the working ETC prototype will be built. A lot of time, energy and
money have been contributed to make sure this project is achievable.
