PENGARUH PENGGUNAAN JENIS BUSI DAN VARIASI PENAMBAHAN CAMPHOR DALAM PREMIUM TERHADAP KADAR EMISI GAS CO DAN HC PADA SEPEDA MOTOR HONDA SUPRA X 125 PGM-FI TAHUN 2006

Abstract

The purpose of this research to investigate: (1) The effect of sparkplug types to exhaust gas emissions level of CO and HC on Honda Supra X 125 PGM-FI 2006motorcycle. (2) The effect of camphor addition  in premium to exhaust gas emissions level of CO and HC on Honda Supra X 125 PGM-FI 2006motorcycle. (3) The interaction of sparkplug types and camphor addition  in gasoline to exhaust gas emissions level of CO and HC on Honda Supra X 125 PGM-FI 2006motorcycle.  (4) Exhaust gas emissions level of CO and HC on Honda Supra X 125 PGM-FI 2006motorcycle after changed the sparkplug type and camphor addition  in premium. Based on experimental result can be concluded: (1) The using of sparkplug types and the variation of camphor addition in premium on Honda Supra X 125 PGM-FI 2006motorcycle gave the effect to exhaust gas emissions level of CO and HC. (2) The lowest exhaust gas emissions level of CO on standard sparkplug with 4 gram of camphor in 1 liter premium was 0.168%. The lowest exhaust gas emissions level of CO on platinum sparkplug with pure premium was 0.176%. The lowest exhaust gas emissions level of CO on iridium sparkplug with 4 gram of camphor was 0.176%. (3) The lowest exhaust gas emissions level of HC on standard sparkplug with 8 gram of camphor was 303 ppm. The lowest exhaust gas emissions level of HC on platinum sparkplug with pure premium was 311 ppm. The lowest exhaust gas emissions of HC level on iridium sparkplug with 8 gram of camphor was 380 ppm. (4) The lowest exhaust gas emissions level of CO and HC test with the interaction of sparkplug type and camphor addition in premium was using standard sparkplug and 4 gram of camphor adition in 1 liter premium.
