Abstract
Dari penelitian ini didapatkan mapping durasi injeksi yang tepat pada putaran 2000 hingga 4000 rpm adalah 150%, sedangkan pada putaran 5000 hingga 8000 rpm, durasi terbaik 125%. Sedangkan untuk mapping waktu pengapian didapatkan pada rentang 16° dan 20° BTDC untuk rasio kompresi 12, 12,5, dan 13. Berdasarkan hasil afr E0 ecu programable pada rasio kompresi 11 didapatkan nilai rata – rata sebesar 13,154 yang berarti kondisi campuran udara dan bahan bakar berada di bawah afr stoikiometri yaitu 14,7. Sedangkan untuk hasil afr E50 ecu programable pada rasio kompresi 11 didapatkan nilai sebesar rata – rata 11,160 yang berarti kondisi campuran udara dan bahan bakar berada di bawah afr stoikiometri yaitu 12,6. Hal tersebut menunjukan bahwa engine Honda CB150R beroperasi pada afr di bawah stoikiometri dari bahan bakar yang digunakan. Sehingga engine Honda CB150R memiliki karakteristik daya menjadi meningkat dan tidak terjadi detonasi, akan tetapi nilai waktu konsumsi bahan bakar akan menurun serta emisi CO dan HC meningkat
=================================================================
Experimental result show that the correct injection duration mapping on the 2000 to 4000 rpm is 150%, and on the 5000 to 8000 rpm the best duration is 125%. Meanwhile, for the time mapping of the ignition time on the range of 16° and 20° BTDC for the compression ration of 12, 12.5 and 13. Based on the result of AFR E0 ecu programmable on the compression ratio 11 the average value is 13.154, which means the condition of air and fuel mixture is below the stoichiometric AFR of 14.7. On the other hand, for the result of afr E50 ecu programmable of the compression ratio 11 the average value is 11.160, which means the condition of air and fuel mixture is below stoichiometric AFR of 12.6. This matter shows that Honda CB150R engine operate on afr below the stoichiometry of the fuel that we used. So the Honda CB150R have the power characteristics increasing and detonation is not happening, however the time consumption of the fuel will decrease, and the emission of CO and HC will increase.
