Another reason for getting very NOx particulates for the blend 50D50H is shorter the ignition delay occurs for this test fuel, because basically, diesel is a highly oxygenated fuel 68 , When it oxidised with hydrogen gas at elevated temperatures results in quicker burning of nitrogen molecules with oxygen molecules tending to achieve the combustion faster and faster with complete combustions followed by least particulates 69,70 0.50D50H attains very Lowest NO x compared to other blends, because Reduced Mean Combustion Temperature The generation of NO x (nitrogen oxides) adheres to the thermodynamic (Zeldovich) cycle, which escalates significantly when flame values surpass around 1800 K.In a dual-energy configuration of 50H50P (pyrolysis of hydrogen into oil):The element hydrogen combusts rapidly yet can be well regulated (lean combustion with surplus air).This type of oil comprises oxidized molecules and typically exhibits a lower calorie density, resulting in a reduced cumulative heating rate compared to diesel fuel at equivalent loads
