HC EMISSION STABLE AND POWER OPTIMATION OF THE MOTORCYCLE LPG ENGINE BY HEAT TRANSFER TO THE INJECTOR

This study was conducted on a motorcycle engine that already has bi-fuel, with liquid phase LPG injection. However, when conducting experiments the concentration of substances in exhaust gas, results show hydrocarbon tests different effects. It is possible to see sudden high at some point time. Over time, nozzle tip will gradually form ice around due evaporation and heat collection. When forming large lumps, this break off move into combustion chamber. A part not yet mixed air create an explosive mixture, process completed. The solution proposed use method transfer body by electronic heating device. experiment measured brake power wheel, fuel consumption, pollutants gas according each controlled temperature supply body. With result, suitable selected ensure achieves most optimal consumption eliminates phenomenon abnormal concentration. From test results, 30OC adjusting device nozzle.
