The main purpose of this work is to evaluate the possibilities of using the hydrogen as a clean fuel for the small horsepower engines. Due to the increasing spark ignition engine in the world, this caused deteriorating quality of air and due to the hydrogen combustion properties, which has a great effect on improving the performance of spark ignition engine. The engine was operated separately with each of Hydrogen or gasoline using a control valve, using the Ultrasonic-Hydrogen Electrolyzer System. In this article, all performance parameters of Ultrasonic-Hydrogen Electrolyzer System (UHES) were carried out such as the rate of hydrogen production and system efficiency under a different waveforms and wave frequency. The performance parameters of small horsepower gasoline single cylinder engine are carried such as the engine torque, engine revolution and power efficiency of an engine efficiency under the hydrogen gas-fuelled comparative with the pure gasoline-fuelled engine. The experimental results reveal that the triangular waveform has the maximum hydrogen production, UHES efficiency was 72 % and the hydrogen can be increased power efficiency up to 9-10% by using hydrogen without gasoline.
