Analisa Campuran Metanol–pertalite Terhadap Kinerja Dan Suhu Kerja Motor

Abstract

The study aims to determine the effect of using a mixture of methanol add on to pertalite to the performance of gasoline engines, especially injection system with a capacity of 250 cc engine with two cylinders. This research used experimental method with variables used in this research is mixture of pure pertalite (P), mixture of pertalite - methanol 90% - 10% (PM1), mixture of pertalite - methanol 80% - 20% (PM2), mixture of pertalite - methanol 70% - 30% (PM3), mixed pertalite - methanol 60% - 40% (PM4), 50% - 50% (PM5) pertalite - methanol mixtures, pertalite - methanol 40% - 60% (PM6). Variable related in this research is power, torque and working temperature of the engine. The results of this study indicate that the addition of methanol with pertalite fuel tends to produce lower power and torque, while the temperature of the radiator and exhaust system shows that the use of methanol mixture with pertalite fuel can significantly increase the engine temperature of the vehicle.

Pengaruh Penambahan methanol Terhadap Emisi Bahan Bakar Mesin Sepeda Motor Berbahan Bakar Pertamax 150 CC

“…Kandungan oksigen yang tinggi pada methanol dan pertamax mengakibatkan pembakaran di ruang bakar menjadi lebih baik dan emisi gas buang menjadi berkurang. [15], [21] [22].…”

Methanol-Gasoline Fuel Effectiveness Analysis Study

“…The material used was methanol with a concentration of 100% mixed in gasoline and resulted in an increase in the temperature of combustion in the combustion chamber[10]. The methanol mixture in the fuel mixture affects the engine torque and power: the more methanol in the fuel mixture, the lower the power and torque[11].The highest efficiency value obtained was the 20% methanol gasoline mixture for all test conditions. The best performance on gasoline is on unleaded gasoline.…”
