Abstract—Since burning of hydrogen emits fewer pollutants, it has been using as a clean alternative or auxiliary fuel of engines. This study is to develop a diesel/ hydrogen-rich gas dual fuel engine with methanol steam reforming method and design of EGR (Exhaust Gas Recirculation) system to investigate engine performance and exhausting pollutants. The measured items are composed of the gas pressure of cylinder, crank angle, diesel consumption rate, hydrogen consumption rate, air flow rate, and emissions (HC, CO2, NOx, and Smoke), and the contents of hydrogen-rich gas. The authors analyze how the hydrogen-rich gas addition with EGR influences the combustion performance and emissions. The heat recovery reforming system can solve the storage and producing problem of hydrogen. Furthermore, the authors little altered the engine structure, and it is easy to put the energy saving and pollutants decrease into effect.
