experimental investigation of hydrogen fuelled homogeneous charge compression ignition(hcci) engine

Declining oil reserves and increased fuel prices have, together with increased awareness of the environmental impacts of burning hydrocarbon fuels, led to an interest in alternatives to fossil fuel based propulsion and power generation.One such alternative is to use hydrogen as an energy carrier [2]. As a result various alternative fuels (such as liquefied petroleum gas (LPG), compressed natural gas (CNG), hydrogen, vegetable oils, bio gas, producer gas) have been considered as substitutes for hydrocarbon-based fuel and reducing exhaust emissions. Of these, hydrogen is a long-term renewable and less-polluting fuel[1].
