چکیده
The number of motorized vehicles increases from year to year, the exhaust gases generated these cause air pollution by 70 80 percent, so efforts need be made control gas emissions. Considering danger emissions, effort that needs and reduce is engineering modification lines. Engineering lines, namely innovating adding aluminum scrap. Researchers will conduct experiments manufacture tools initial testing on see observe composition produced standard exhausts. elements observed are CO value, HC CO2 value as comparison data. tool used Gas Analyzer. From results analysis, data emission tests with an average engine speed 4000 rpm, pipe temperature 40 o C 45 C, were obtained. After exhaust, then modified addition scrap 60 gr, gr obtained best conclusion t emissions added when compared exhaust. yield fell 11.7%, 4.26%, 1.59%.
