Abstract

The increasing population of motorcycle causes the amount of fuel that is burned. Based on the flowing energy of internal combustion engine, 100% fuel and air combustion produce 25% for driving operation, while 40% exit as exhaust gas, 25% as cooling and 5% friction. The amount of exhaust gas has the potential for heat utilization. This research aims to utilize heat of exhaust gas into electrical energy by using thermoelectric module. This research uses fin and non-fin variations that are installed on heat exchanger as heat absorbing media, and use water block as cooling media. In this research using 12 thermoelectric with SP1848 27145 SA type which is installed on heat exchanger and in pairs on exhaust gas pipe Supra X 125 cc. The test is done by variation of fin and non-fin at idle engine rotation, 2000 rpm, and 3000 rpm. The results showed that non fin variation obtained higher result than fin variation. The heat side temperature, difference temperature, output voltage, output current and output power increase when the engine starts up for 120 seconds and decreases when the engine is shut down for 180 seconds. In the load less test the heat side temperature, the temperature difference and the highest output voltage at 3000 rpm rotation are 78° C, 34.8° C and 14.44V. On the load test the heat side temperature, temperature difference, voltage, current , and the highest output power at 3000 rpm rotation are 90 ° C, 37.8 ° C, 2.95 V, 0.26 A, and 0.76 W. The amount of output power generated by thermoelectric module is directly proportional to the charge in temperature difference. Keywords: Exhaust gas, Fin, Thermoelectric, and Power.
