The project Voice Operated Fuel Injector is developed for injecting fuel to the users vehicle by voice signal of the user is called Voice Operated Fuel Injector System. This project is user-friendly and easy to use. This project is good idea for Mechanical and automobile engineering students.

Voice Operated Fuel Injector

The hardware requirements of this proposed project are given below:

  1. LCD display unit
  2. Voice signal processing circuit
  3. Microphone
  4. Micro controller unit
  5. Valve circuit

User’s voice signal over the microphone plays important role in the working of this project. The user of the system will tell his fuel requirement like 1 liter, 3 liter etc to the micro controller through microphone. The incoming sound energy will be converted in to electrical energy by the microphone. It is connected to voice signal-processing circuit which analyzes the frequency range of incoming voice. Then voice signal will be sent to the micro controller unit, which controls the output valve circuit.

The voice signal processing circuit is used to detect the voice signal of user. Voice signal plays an important role in the opening and closing time mechanism of output valve circuit. The required level of fuel which we told over the microphone is displayed on the LCD display unit. It is controlled by the microcontroller which is connected to it. We can find the fuel output from this LCD display unit.

This project topic is only for students of Engineering. Here we shared just ideas of student project and it may take some further steps to convert to live projects. First of all I would like to say thanks to Mysore university internal guides for sharing their passion for this work with me. As mentor, my internal guide taught me a great deal about more than the subject matter at hand.
