Rancang Bangun Generator Gas Oxy Hydrogen Pada Mesin Pembakaran Dalam(Internal Combustion Engine) Untuk Penghematan Bahan Bakar

The Purpose of this research is to design and develop an oxy-hydrogen gas generator to be injected into a car engine. Design method used was morphological method, which focuses on the design of the appliance functions to be achieved so that the shape of the tool will adjust itself. From the design process we got several concepts and then selected based on weighted decision matrix method to decide which one is appropriate to the following needs. Finally tool concept that developed are oxy – hydrogen generator with dry cell system. This tool function are to process hydrolysis reaction, which is chemical reaction that split water (H2O) into oxygen (O2) and hydrogen (H2), this gas mixture are called oxy-hydrogen which is then used to increase engine performance. The tool are installed to a petrol engine car with capacity of 1800cc with injection system and then dyno tested, the results are average power increasement of 5.73 HP and average torque increasement of 26.2Nm. The fuel consumption test are using stationary diesel engine connected to an electrical generator with load variety between 200 watts – 1600 watts, the result are maximum fuel saving until 6 % and effective until 1200 watts load.
