During the last decade the use of alternative fuels for diesel engine has received renewed attention. The interdependence and uncertainty of petroleum based fuel availability and environmental issues, most notably air pollution, are among the principal forces behind the movement towards alternative source of energy. Hydrogen is expected to be one of the most important fuels in the near future for solving greenhouse problem for protecting environment and saving conventional fuels. In this experimental investigation, a diesel engine using hydrogen as fuel was investigated with diesel as an ignition source for hydrogen. Hydrogen was injected into the intake port, while diesel was injected directly inside the cylinder. The parameters such as injection timing and injection duration of hydrogen were varied for a wider range at a constant injection timing of 23^∘ before injection top dead center (BITDC) for diesel. The …
