Abstract : This paper represents the design of a real-time monitoring system of air filter functioning in large-scale diesel generators, specifically the old generators that lack inbuilt emission control such as the Exhaust Gas Recirculation (EGR). The system was efficient in tracking important parameters such as airflow rate, temperature, pressure and humidity, providing accurate information on the condition of air filters. The findings showed that engine performance and emissions are greatly affected by the conditions of air filters. Installing a clogged air filter led to a reduction in airflow and an increase in engine stress which led to a greater consumption of fuel whilst operating in the absence of a filter allowed the maximum airflow but increased the chances of pollutants reaching the engine. EGR system was very effective in reducing NO2 by reducing the combustion temperature with the CO and CO2 emissions kept within acceptable ranges. Using the EGR system along with incorporation of real-time monitoring was used to guarantee maximum engine performance and reduced hazardous emissions. The combination of microcontrollers and sensors allowed to collect data and control it accurately, which guaranteed the efficiency of engine operation. Remote monitoring was made possible through the digital interface and cloud storage, thus making informed decision-making and preventive maintenance a possibility. The realtime data and alerts provided by this system optimized the maintenance schedules, minimizing potential occurrences of unexpected breakdowns and premature replacements, which enhanced the operating efficiency of the system and provided cost-Saving.
