PENGARUH PANJANG PEGAS KATUP MEMBRAN AIR INDUCTION SYSTEM (AIS) TERHADAP EMISI GAS BUANG CO, HC DAN CO2 PADA SEPEDA MOTOR YAMAHA BYSON TAHUN 2010

The purpose of this research is are to determine the influence of membrane valve springs length Air Induction System (AIS) to the exhaust gas emissions CO, HC and CO2 on Yamaha Byson motorcycle 2010. This research was conducted at the Laboratory of Automotive Mechanical Engineering Education Program, JPTK, FKIP, UNS Surakarta to the address on the road Ahmad Yani no. 200 Kartasura. Test of CO, HC and CO2 exhaust gas emissions was used a gas analyzer STARGAS 898 type. This research was used experimental methods. The population in this research were a motorcycle Yamaha Byson in 2010 and sample in this research was a motorcycle Yamaha Byson in 2010 with 45P010961 engine number. Techniques of data analysis in this research using descriptive data analysis. Based on this research can be conclude: (1) The results gas emissions levels, the shorter the AIS membrane valve springs are used, the higher the resulting CO. (2) The results HC exhaust emissions levels, the shorter the AIS membrane valve springs are used, the lower the resulting HC. (3) The result levels of CO2 emissions, the shorter the AIS membrane valve springs are used , the lower the CO2 produced. Of the all emissions in this test, the all still under standard exhaust emissions limits released by the ministry of the environment number 05 in 2010
