Improving engine performance with distillated water-methanol

The effect of detonation is the reduction of engine performance, increasing specific fuel consumption and increasing the quality of exhaust gas emissions. This experimental research aims to get solved with applied water injection system at gasoline engine. This study uses experimental research. The testing of engine performance is done by giving the treatment of Honda mega pro 2009. WaI (Water Injection) system is mounted on the motorcycle with the fluid composition:(1) aquadest 100% and methanol 0%, (2) aquadest 90% and methanol 10%, (3) aquadest 80% and methanol 20, (4) aquadest 70% and methanol 30, (5) aquadest 60% and methanol 40%, (6) aquadest 50% and methanol 50%.The result shows, by adjusting the percentage of methanol and aquadest could decrease the specific fuel consumption, increase the power of engine and reduce Carbon Dioxide (CO2) emission.
