Abstract An important measure that shows the total amount of greenhouse gases released into environment is carbon footprint by using fossil fuels. Sustainable alternatives are seen as an effective step in both preventing depletion fuels and combating climate change. To overcome these negative consequences, use area with hydrogen becoming increasingly popular among fuel researchers. However, application a can potentially increase NOx emissions. For this reason, water–urea solution 5% volume was added to diesel–hydrogen dual engine. Subsequently, intake manifold supplied 1 LPM hydrogen. Different engine loads were evaluated, while diesel operated at 1500 rpm rated speed. As result, addition urea led decrease BSFC 23% improvement thermal efficiency 25% compared fuel. Blend oil decreased EGT 2% lower than oil. NOx, CO, HC CO 2 concentrations 5, 61, 13 53%, respectively, when mixed about Engine performance may be improved, exhaust pollutants reduced utilizing combined alternative
