Improving the fuel economy and reducing emissions of greenhouse gas from vehicle sources have been a majority focus of research have been recently studied. Another way to achieve this, alternative fuels which can be used in full or in-part, substitute petroleum-derived fuels with current internal combustion engine technology, so that the benefits of Clean energies may be quickly understood. The current research attempted to investigate the efficiency and emissions of a diesel engine using traditional diesel fuel with hydrogen mixtures and water-built in oxygen. Upon the induction time, it has added small quantities of hydrogen and oxygen into the air flow, Current Method of Injections or Changes were made to existing engines. The operation found that the fuel consumption, exhaust engine CO2 increases with decreasing CO by injecting small amounts of on-site generated hydrogen and oxygen into the intake manifold of CI engine through induction. The specific fuel consumption has been reduced by 11.53% because of its higher calorific value. The brake power has been increased by 11.8% because of its complete combustion, brake thermal efficiency increased by 4.85% from the conventional mode. Mechanical efficiency increases by 6.83% along with indicated thermal efficiency. The emissions like CO, HC, SMOKE has been reduced by 25%, 22.22% and 11.38% respectively with increase in 3.410% and 22.43% of CO2 and NOX respectively. The combustion in the in-cylinder analysis did not show any significant improvement in the properties of the cylinder pressure. This study also established an optimum level of hydrogen to the engine's NOX rates.
