Emissions of a direct injection diesel engine by adding hydrogen to the inlet manifold

Global Warming is imminent. Emissions must be decrease immediately. However, there are many challenges to overcome in order to successfully reduce emissions. It must be a cheap, abundant, efficient solution that occupy a small space and can be retrofitted to existing diesel engines.The objective of this experiment is to research the effect of adding Hydrogen in diesel engines. It is technically possible to inject in the inlet manifold Hydrogen in diesel engines. The experiment was conducted in a one-cylinder engine, in various running conditions. It was tested with various flow rates of hydrogen, also.The tests seek to verify that the hydrogen injection adapts to engine operation without major modifications. Subsequently, various tests were performed to measure the engine emissions. This research involves several experiments made in diesel engines to gradually blend hydrogen into it resulting in fewer emissions and helping to develop a market demand for green hydrogen, letting economies of scale to reduce prices and increase competitivity.The study is in the context of a country like Uruguay where electricity is 98% renewable. Nowadays is facing the issue of dealing with surplus of electricity in times of low demand and how to satisfy peak demand. The hydrogen might be a solution, being produced when energy is abundant, stocking up for consumption and creating an energy storage when demand of energy increase.Furthermore, this research analyzes the latest development in new lightweight materials capable of resisting 750 bars of pressure, increasing the energy density of hydrogen making it an alternative for the use of scrubbers, with the advantage of not creating any sludge or waste.
