Currently all countries are facing a common problem of fossil fuel shortages, and many researchers are finding various solution to provide green energy. A large part of energy requirement is there in the transport cars, bike, buses, trucks, auto-rickshaw etc. current these vehicles run on gasoline (petrol), diesel and CNG. In most cases fuel is not combusted efficiently in these vehicles and black thick smoke is seen in exhaust. Oxyhydrogen (HHO) is a technology here we generate hydrogen gas using electrolysis of water. This gas is added in low percentage along with fuel which increases the mileage by 10-20%. Not only mileage it cleans system from inside and removes all carbon deposits, which improves engine performance and decreases knocking sound of engine. The proposed design generates gas at constant rate so that HHO cells runs smoothly with better efficiency. A constant current system is designed to run the HHO cell with current monitoring and PWM methods are used to control the current with the help of power MOSFET and embedded system. For smaller HHO cells 12V supply is required but for larger HHO cell we 110V regulated DC supply with high current capability which is also part of our research.
