Summary:

In the power industry, high-power Diesel Generator (DG) sets often utilize high power V-engine cylinder configurations to enhance power output within a compact design, ensuring smoother operation and reduced vibration. In this V-engine configurations, the exhaust gas mass flow rate is significantly higher compared to inline engines of similar displacement, due to the greater number of cylinders operating in a compact space, which leads to a higher volume of exhaust gases expelled in a shorter duration. This necessitates the use of a dual Exhaust After Treatment System (EATS) to effectively manage NOx emissions. High-power gensets typically emit NOx levels around 9 g/kWh, presenting significant challenges for developers in adhering to stringent emission standards. To address these challenges and meet CPCB IV+ emission norms, we propose a dual urea dosing system integrated with a novel control strategy aimed at optimizing the treatment of exhaust gases. This paper introduces a dual exhaust system equipped with dual urea dosing units. By employing two controller units, we ensure compliance with On-Board Diagnostics (OBD) requirements while effectively implementing advanced software concepts. Our approach not only enhances the efficiency of NOx reduction but also provides a robust solution for high-power diesel generators, paving the way for more sustainable operations in the power sector. Furthermore, we explore the integration of real-time monitoring and adaptive control mechanisms to respond dynamically to varying load conditions and exhaust characteristics. This ensures optimal dosing of urea, enhancing the overall performance of the EATS. This study discusses the design, implementation, and performance evaluation of the proposed system, highlighting its potential to significantly lower NOx emissions while maintaining operational efficiency in high-power diesel generator applications
