ANALISIS VARIASI WAKTU TERHADAP KARAKTERISTIK ALIRAN GAS BUANG DAN PERUBAHAN MASSA FILTER BERBAHAN SELULOSA PADA MESIN DIESEL YANMAR L 40 AE-STM
Air pollution caused by diesel engine exhaust emissions such as CO, NOx, HC, PM 2.5, and SO2 can have harmful effects on both health and the environment. To reduce this pollution, efforts are being made by developing filter media made from natural and environmentally friendly materials, specifically filters made from cellulose acetate filaments. The main goal of this research is to analyze the characteristics of exhaust gas flow using a cellulose-based air filter and to measure the mass change of the filter in a sign of the effectiveness of the filter in a Yanmar L 40 AE-STM diesel engine. The testing method was carried out by operating the Yanmar L 40 AE-STM diesel engine, which was equipped with a cellulose air filter, on the exhaust passage. The test was conducted for durations of 5, 10, and 15 minutes, with the engine running at RPMs of approximately 1500, 2000, and 2500. This study's results show that the exhaust gas flow passing through the cellulose based air filter is in the laminar flow regime, with Reynolds numbers ranging from 385 to 639 across all test duration variations. The longer the test duration, the higher the actual flow rate, pressure drop, and pressure loss coefficient. There is also an increase in the mass difference of the cellulose filter for all test durations with RPM around 1500, 2000, and 2500 a successful outcome for all variations of test time with RPM settings around 1500, 2000, and 2500.
