PENGARUH KATALIS OKSIDA TEMBAGA + KROM TERHADAP EMISI GAS CO, C02 DAN HC PADA KENDARAAN BERMOTOR

Abstract

The transition metal oxide was used as catalytic converter. The metal alloy consisted of copper and chrom. The gas examination included carbon monoxide (CO), carbon dioxide (CO₂), and hydrocarbon (HC) at different engine rotation, and variation of layers 3, 5, 7, 11, and 15. The copper oxide had the highest removal of CO 35.6% at 2000 rpm, while HC removal was 34.13% at 3000 rpm. Engine slow down due to copper oxide catalyst addition was 5.2%. The best performance copper and chromium oxides with 15 layers of chromium, when the removal of CO and HC was 64.05% and 49.5% respectively at the engine speed of 2000 rpm and 3000 rpm. Having experimented as mentioned above, the engine power dropped about 3.4%.
