Abstract :Reducing nitrogen oxide insert ignore into journalissuearticles values(NOx); emissions is of great importance in terms of environmental sustainability and air quality. This study is a review that examines various applications aimed at reducing NOx emissions. Below is a summary of the evaluation of technologies, including the common rail system, exhaust gas recirculation insert ignore into journalissuearticles values(EGR);, Miller cycle, direct water injection, emulsified fuel, and selective catalytic reduction insert ignore into journalissuearticles values(SCR);. The common rail system, EGR, and Miller cycle can generally be considered as combustion control-based methods for reducing NOx within the cylinder. Direct water injection and emulsified fuel aim to lower temperatures inside the cylinder by utilizing the high internal heat of evaporation of water. Selective catalytic reduction is a technology where NOx in the exhaust gas is converted into nitrogen gas and water vapor through the use of a catalyst. This study evaluates the effectiveness and applicability of various technologies used to reduce NOx emissions. Each method may have different advantages and disadvantages. Additionally, there may be certain limitations and variations depending on the application areas of these methods. Therefore, a careful assessment is necessary to determine the most suitable technology or combination of technologies for reducing NOx emissions.
