Pengujian Filter EGR (Exhaust Gas Recirculation) Terhadap Efek Blow By Gas Berbahan Serat Kedelai Edamame Sebagai Upaya Untuk Mengurangi Emisi Gas Buang Mesin Diesel

Abstract

The growth of diesel-engined vehicles in Indonesia is now increasing as the population grows. Diesel-engine vehicles are in great demand because they have high economic value compared to gasoline-engine vehicles because Diesel-powered vehicles require Solar fuels that cost much less than gasoline-engine vehicles. And also Diesel-engine vehicles have much more power to carry large and large items. However, Diesel-engine vehicles have a negative effect as well as causing large air pollution to the environment. Due to diesel engine exhaust emissions have a high concentration. This high density is caused by the Blow By gas effect of bringing back the remaining oil called soot into the combustion chamber after the combustion process. So in this study the authors modify the Filter EGR (Exhaust Gas Recirculation) from filter made from paper with Filters made from Edamame soybean Fiber Composite. According to Xiaobing Liu Research (2017) that Soybean Fiber can absorb particulate dust with high efficiency level that is between 99.94% and 99.95%. It is expected that this modification may reduce the level of Diesel engine exhaust gas concentration or so-called Opacity Level to the Blow Effect By the gas. From the results of the research, it is found that before the EGR filter (Exhaust Gas recirculation) installed made from Edamame soybean there is an Opacity value of 40% with a value of k-value of 2.58 1 / m. And after EGR filter made from Edamame soybean fiber installed there is a decrease of Opasitas level by 27% with value of K-Value equal to 1,6 1 / m. testing conducted on vehicles at 5000 rpm. Keywords— mesin diesel, tingkat opasitas, serat komposit kedelai, filter EG
