Hydrogen is expected to be one of the most important fuels in the near future for solving the problem caused by the greenhouse gases, protecting environment and saving conventional fuels. In this study, a dual fuel engine of hydrogen and diesel was investigated. Hydrogen was injected the intake port with air and diesel was injected into the cylinder. Using Electronic Gas Injector and Electronic Control Unit (ECU), the injection timing and duration was varied. In this investigation, a single cylinder, KIRLOSKAR AV1, DI Diesel engine was used. Hydrogen injection timing was fixed at TDC and injection duration was timed for 30°, 60°, and 90° crank angle. The injection timing of diesel was fixed at 23° BTDC. When hydrogen is mixed with inlet air, emissions of HC, CO and CO2 decreased without exhausting smoke while increasing the brake thermal efficiency.
