Purpose

• Create a device that controls and monitors the
  electrolysis cell
• Achieve maximum performance
• Reduce harmful emissions

4
What is an O2 Sensor?

• Measures the amount of oxygen in the exhaust
• Analog output
• Controls Air/Fuel Ratio

5
What is an Electrolysis Cell?

• 2H2O O2 2H2

O2 H2 Combustion
6
Motivation

• Previous research has shown
• Market is essentially untapped
• Gas mileage increased by up to 68
• Hydrocarbon emissions decreased by 90
• Increased horsepower

7
Design Requirements

• Conform to FCC Regulations, Class-B Device
• Run off cars battery (8V to 14 V)
• Keep H20 temperature under 97oC
• Monitor pressure in electrolysis cell
• Device does not interfere with everyday
  operations of the vehicle

8
Control System
TIs MSP430 Micro-controller will monitor and
relay messages through the control box.
