Hydrogen’s combustion properties made it as a gifted fuel and energy carrier to combat the current scenario of depletion of the fossil fuels and crisis of environmental pollution problems. Its superior thermo physical properties and least toxic emissions are favorable to use it in an internal combustion (IC) engine as an alternative fuel. This paper describes an experimental analysis of performance and emission parameters for a four cylinder, four stroke SI engine by supplementing hydrogen fraction with gasoline. Tests were carried out by using hydrogen fraction from 0-10% in step of 2% by volume. Study revealed an improvement in brake power, efficiency and brake specific energy consumption up to 8% hydrogen fractions in comparison with gasoline operation while volumetric efficiency decreased for all hydrogen fractions. Carbon monoxide (CO), Hydrocarbons (HC) emissions were reduced and Nitrogen oxides (NOx) was slightly increased for all hydrogen fractions than gasoline.
