Abstract

This paper proposes an application of microcontroller for controlling the HHO dry cell regarding to separate hydrogen gas from water. The proposed control system consists of a display control microcontroller, a PWM signal generation microcontroller, key switches, buck converter, a separator and sensors. The experimental results show that the proposed control system can regulate the output current of the HHO dry cell constantly; even under the significant variations of battery voltage or the change in dry cell internal resistance. Furthermore, the proposed system could also protect the system operation by limiting the minimum voltage for the battery and maximum output current and temperature of the HHO dry cell. The test of the prototype truck by running for 15,000 kilometers was found that the truck could save the fuel approximately by 10 % when applied the proposed control system as the co-fuel source. In addition, one liter of pure water could be used for the operating engine and could operate continuously up to 800 kilometers.
