Development of Cooling and Exhaust Emission Reduction System with Thermoelectric-Based

Vehicle exhaust emissions are a major source of air pollution. This research aims to reduce emissions by developing a thermoelectric system using Peltier modules integrated with a single-room type heat exchanger. The cold side of the Peltier serves as a fuel cooler. The method used is an experiment with variations of large and small radiators. The results show that the small radiator increases the fuel temperature to 39.5°C compared to 34.4°C in the large radiator. This condition reduced CO emissions from 4.99% to 4.22%, and HC from 429.3 ppm to 294.7 ppm. The cold side temperature of TEC 1 on the large radiator reached -8.6°C, while that of the small radiator was only -1.1°C. Although cooling performance decreased, the increase in fuel temperature favored combustion efficiency and emission reduction.
