PENGARUH VARIASI INJEKTOR DAN BAHAN BAKAR TERHADAP EMISI GAS BUANG PADA CB 150R TAHUN 2013

Technological developments in the automotive world are increasing rapidly, including the change from conventional combustion systems to injection systems. Where in the injection system, the type of injector and fuel affect exhaust emissions which cause pollutants including CO, HC, NO2, SO2, Pb which can indirectly interfere with human health, especially the respiratory system. In this study the researcher wanted to know the effect of factor A using variations of the 6-hole, 8-hole, 10-hole injectors and factor B the use of pertalite, Pertamax, and Pertamax turbo fuels and analyzed using the ANOVA method and it is known that injector variations affect exhaust emissions because Fcount ˃Ftable, namely Fcount at CO levels of 22496.25 and Ftable of 3.26, at HC levels Fcount of 2261.4178 and Ftable of 3.26. And there is no significant effect on exhaust emissions caused by the type of fuel because Fcount˂Ftable. Where the CO Fcount is 0.446 and Ftable is 3.26. and the results of HC levels Fcount of 2 and Ftable of 3.26. And there is an interaction between injector and fuel variations on CB150R exhaust emissions due to Fcount˃Ftable where the results of CO Fcount are 32.09 and Ftable are 2.63. and the results of HC are known to be Fcount of 13.72 and Ftable of 2.63. The best result for CO levels are found in 8-hole injectors with Pertamax turbo fuel of 0.144% and the best results for HC levels are found in 6-hole injectors with Pertamax turbo fuel of 51ppm.
