Abstract

In this study we are conduting research on the effects of the use of a catalyst (Broquet) and also emission levels exhaust of motorcycle 113 cc fuel capacity which use Premium RON 88 and Pertamax RON 92 as fuel. This study also to do a comparison of engine performance (torque,power specific fuel consumption,thermal efficiency,air fuel ratio) The result obtained the engine performance was increased by using soaked fuel with broquet. By using premium the torque increase up to 5 % , The power increase up to 5.2 %  SFC decrease of 12 %while using pertamax the torque increase of 1 %, power increase of 1 % SFC decrease of 3 %. The emission of exhaust Reduce by using soaked fuel with broquet. While using premium the content of CO was decrease of 30%, HC decrease of  11 % and CO2 increase of 38 %. By using pertamax the content of  CO was decrease of 10 %, HC decrease of  19 % and CO2 increase of 9  % Keywords: engine performance, Broquet catalytic,catalyst.

Abstract

This research conducted by experimental analyze the performance of Otto four stroke engine, single cylinder with 108 cc, and work with ratio compression ,2:1. Fuel that used is pertalite RON 90. The research use single and double magnet with 2500 Gauss that variate 5 cm, 10 cm , and 15 cm of distance. The result from experimental test that use magnet has reduce spesific fuel consumtion until 29,8 %, improve the engine torsion up to 17, 4%, engine power 16,7 %. Increase thermal efficiency up to 7,51 %. Reduce CO and HC level up to 27% and 18,9 %. Increase CO2 level up to 19,67%  and reduce O2 level up to 21,72 %. Keyword:  Otto engine 108 cc, Magnet 2500 Gauss, Engine performance, Gas emission.
