The intake manifold is slightly modified to accommodate the hydrogen induction system, where premixed mixture of hydrogen and air is formed in the intake manifold; attaining the excess air ratio of 1.0 to 1.2. With the increment of hydrogen fraction the fuel leaning (Gasoline) is attained and achieving economical fuel consumption rate. The decrement in torque characteristics is compensated with the increase of hydrogen fraction. The hydrogen induction improves the combustion rate and mean effective pressure; shortens the flame propagation, maximize the heat release rate and peak pressure attainment. On the emission side consistent decrease in CO and HC emission; and increase of NOx emission since the mean gas temperature has increased. The cycle to cycle variation during the lean operating condition at 1.2 shows the combustion stability and effective flame propagation. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.
