Diesel engine exhaust emissions are one of the contributors to increased air pollution. One automotive technology that can reduce diesel engine exhaust opacity is the diesel particulate filter (DPF). The purpose of this research is to analyze the effectiveness of using glass wool and stainless-steel-based DPF technology to reduce the opacity of four-stroke diesel engine exhaust. The research method was carried out experimentally in an automotive laboratory. The diesel engine exhaust opacity testing standard uses SNI 19-17118.2-2005, which refers to SAE J1667. The research results show that glass wool and stainless-steel- based DPF technology is proven to be effective in significantly reducing diesel engine exhaust opacity by up to 90.85% compared to the use of a standard muffler.
