Pemamfaatan logam sisa permesinan pada knalpot guna mengurangi pencemaran udara

Exhaust gas emissions from motorized vehicles also contribute to air pollution in our environment. So it is necessary reduce so that the negative impacts on humans, animals and environment can be reduced. Hoping making alternative tools exhaust 100cc motorcycle vehicles. With experimental methods testing of motor vehicle with a comparison standard data. Tests are carried out determine results emissions, plus modified addition scrap ST-40 iron. The elements observed CO value, HC value CO2 as comparative tool will used store view these Gas Analyzer. This useful for measuring portion composition combined gases. From analysis, obtained emission data an average engine speed 500 rpm, pipe temperature 40 0 C 45 C. After model, then model. In tests added 50 g, 70 90 g iron, was found best way pieces And when compared exhaust, element drops 72.35% 58.70%. decreased 74.28%.
