Driving Towards Sustainability: Examining Truck Emissions and Speed on National Roads

This research aims to determine exhaust emissions and speed of the truck while driving. Measurements are carried out using a mobile emissions analyzer that absorbs emissions from truck exhaust gases. Data collection is carried out by placing a mobile Emission Analyzer on the right side of the vehicle which is capable of absorbing 5 emissions in approximately 5 minutes. The relationship between exhaust emissions and speed uses a polynomial model of the average value of exhaust emissions and speed. The reliability of the mobile emission analyzer uses a multiplier factor to resolve data differences between the mobile emission analyzer and Bosowa equipment, where the CO2 correction factor is 0.666; CO correction factor of 0.243; NOx correction factor of 1.236; HC multiplier factor is 0.764. The research results show that CO2, NOx, smoke, CO and HC emissions form driving cycle patterns. This pattern shows a pattern following a parabolic trend, compound pattern of truck exhaust emissions on good road conditions and speeds of 0 km/h to 49.1 km/h, CO2 emissions 4%-16%, CO 0%-3%, smoke 0%-13%, NOx 0%-12%, HC 0%-11%, and with the truck running in damaged road conditions and speed 0 km/h to 35.8 km/h, CO2 emissions 3%-18%, CO 0%-5%, Smoke 0%-13%, NOx 0%-15%, and HC 5%-14%. Optimum speed values for Truck Exhaust Emission Driving Cycle Patterns on Damaged Road Conditions at CO2 19.16 Km/hour, CO 27.32 Km/hour, Smoke 25.9 Km/hour, NOx 19.7 Km/hour, and HC 27 .32 Km/h. The optimum speed values on a good road are CO2 23.22 Km/hour, CO 33.12 Km/hour, Smoke 33.12 Km/hour, NOx 31.98 Km/hour, and HC 36.82 Km/hour.
