Abstract
Dampak filter oli pada stabilitas oli pelumas dan kinerja mesin telah lama menjadi perhatian para peneliti. Pada tahun-tahun awal, beberapa aditif ditambahkan ke dalam elemen filter oli untuk memperpanjang masa manfaat oli pelumas dalam mesin pembakaran internal. Bahan yang paling banyak digunakan untuk filter oli adalah kertas serat sintetis atau jaring logam di pasaran yang secara efektif dapat menghilangkan kotoran partikel tetapi menunjukkan kekurangan dalam menghilangkan koloid yang tidak dapat larut dari pelumas. Bahan biomassa yang terbarukan dan mudah tersedia, seperti residu tanaman, jerami, dan serbuk gergaji memiliki struktur pori yang kaya dan tekstur alami yang menunjukkan kapasitas adsorpsi besar untuk pewarna, minyak, garam beracun, dan logam berat. Dalam penelitian ini, filter oli serbuk gergaji modifikasi (MSF) dikembangkan dan pengaruhnya terhadap karakteristik emisi dan kinerja mesin diesel dipelajari dibandingkan dengan filter oli mesh logam (CMF) konvensional. Pengujian dilakukan dengan menggunakan mesin diesel direct injection satu silinder, ringan. Dalam kondisi mantap, konsumsi bahan bakar minyak spesifik (SFOC), daya output engine diukur pada empat kecepatan engine yang berbeda. Emisi gas buang nitrogen oksida (NOx), partikel debu (PM), karbon monoksida (CO) dan hidrokarbon (HC) dianalisis menurut IMO. Selain itu, sampel minyak pelumas diekstraksi dari bak mesin di peralatan MSF dan CPF secara individual. Kemudian ditentukan viskositas kinematik, indeks viskositas, titik nyala, titik tuang, jumlah basa total (TBN) dan kandungan logam sampel minyak. Hasil menunjukkan bahwa MSF secara efektif mengurangi akumulasi dan degradasi logam aus dalam minyak pelumas. Dibandingkan dengan CMF, peningkatan 0,02 kW dalam keluaran daya maksimum dan penurunan 2 g/kWh di SFOC diamati untuk MSF. Selain itu, penggunaan MSF secara signifikan mengurangi emisi HC dan PM sementara sedikit meningkatkan emisi CO dan NOx. Hasilnya membuktikan bahwa MSF adalah pilihan yang cocok untuk mesin diesel untuk meningkatkan kinerja mesin dan mengurangi emisi gas buang.

The impact of oil filter on lubricating oil stability and engine performance has been of interest to researchers for a long time. In early years, some additives were added into the oil filter element to extend the useful life of lubricating oil in an internal combustion engine. The most widely used materials for oil filter are the synthetic fiber paper or metal mesh on the market which can effectively remove particulate impurities but show deficiency in the removal of insoluble colloids from lubricant. Renewable and easy available biomass materials, such as plant residues, straw, and sawdust possess rich pore structure and natural texture which show large adsorption capacity to dyes, oil, toxic salts, and heavy metals. In this study, a modified-sawdust oil filter (MSF) was developed and its effect on emission characteristic and performance of diesel engine was studied compared with conventional metal mesh oil filter (CMF). The test was performed using a one-cylinder, light-duty direct injection diesel engine. In steady state, the specific fuel oil consumption (SFOC), engine output power was measured at four different typical engine speeds. Exhaust emissions of nitrogen oxides (NOx), particulate matter (PM), carbon monoxide (CO) and hydrocarbons (HC) were analysed according to IMO emission test procedure. Besides, lubricant oil sample were extracted from the crankcase in the equipment of MSF and CMF individually. Then the kinematic viscosity, viscosity index, flash point, pour point, total base number (TBN) and metal content of oil samples were determined. The results showed that MSF effectively reduced wear metal accumulation and degradation in lubricating oil. Compared to CPF, an increase of 0,02 kW in maximum output power and decrease of 2 g/kWh in SFOC were observed for MSF. In addition, the using of MSF significantly reduced HC and PM emission while increased CO and NOx emission slightly. The results proved that MSF is a suitable choice for diesel engine to improve engine performance and reduce exhaust emissions.
