M Masyarakat pengguna pelumas indonesia (MASPI) mencurigai bahwa penurunan umur pakai cylinder liner di sebabkan korosi oleh biosolar. Obyek dari penelitian ini adalah menjawab apakah biosolar itu menyebabkan korosi pada cylinder liner'?" berapa besar laju korosi yang terjadi.Metode kehilangan berat laju korosi dengan, mengukur kekurangan berat akibat korosi yang terjadi.Hasil penelitian menunjukkan bahwa biosolar menyebabkan terjadinya korosi, dan nilai mpy rata-rata masing-masing sampel original Jakarta adalah 0,09 mpy, sampel second jakarta korosi 0,39mpy, kemudian sampel original biosolar jawa tengah adalah 0,35mpy, dan sampel second 0,65mpy, hasil iaju korsi sampel original jawa timur adalah 0,09 mpy dan sampel second 0,18 mpy.Dari nilai rata-rata laju korosi yang terjadi terlihat jelas bahwa sampel original lebih rendah bila di banding sampel second. Hal ini di karenakan sampel original masih belum tejadi kehilangan oil film dan belum terjadi keausan akibat gesekan antara ring piston dengan cylinder liner, sampel second mpy nya cenderung meningkat karena telah terjadi perlakuan panas pada material tersebut saat proses pembakaran.Dari foto micro struktur non etsa dan etsa yang di lakukan dalam pembesaran 200x dan 400x terlihat warna kehitam-hitaman berbentuk serpihan atau disebut grafite, ini menunjukkan bahwa sampel adalah besi tuang kelabu,kemudian dalam perlakuan etsa diperoleh alur garis material terkorosi yang sangat jelas.Nilai sulfur dan kontaminasi biosolar jawa tengah masing-masing di peroleh nilai untuk sulfur 0,45% dan kontaminasi air 700mg/kg, adalah nilai tertinggi di banding biosolar dari jakarta dan jawa timur.Kandungan sulfur dan kontaminasi air yang tinggi sampel biosolar Jawa Tengah, adalah penyebab dari tingginya laju korosi pada sampel biosolar Jawa tengah, bandingkan sampel dari biosolar Jakarta dan Jawa Timur.
T The Indonesian lubricant user community (MASPI) suspects that the decrease in the life of the cylinder liner is caused by corrosion by biodiesel. The object of this research is to answer whether biodiesel causes corrosion of the cylinder liner'?" How much corrosion rate occurs. The method of losing weight is the corrosion rate by measuring the lack of weight due to corrosion. The results show that biodiesel causes corrosion, and the value of The average mpy for each original sample from Jakarta is 0.09 mpy, the second sample Jakarta is corrosion 0.39mpy, then the original sample biodiesel from Central Java is 0.35mpy, and the second sample is 0.65mpy, the result of the correlation between the original samples from East Java is 0.09 mpy and the second sample 0.18 mpy. From the average value of the corrosion rate that occurs, it is clear that the original sample is lower than the second sample. This is because the original sample has not lost oil film and has not worn out. due to friction between the piston ring and the cylinder liner, the second mpy sample tends to increase because there has been heat treatment on the material when combustion process. From the non-etching and etching micro-structure photos that were carried out at 200x and 400x magnification, a blackish color in the form of flakes or called graphite was seen, this indicated that the sample was gray cast iron, then in the etching treatment the lines of highly corroded material were obtained. The value of sulfur and biodiesel contamination in Central Java was obtained for sulfur 0.45% and water contamination of 700 mg/kg, respectively, which is the highest value compared to biodiesel from Jakarta and East Java. High sulfur content and water contamination in Java biodiesel samples Central, is the cause of the high corrosion rate in biodiesel samples from Central Java, compare samples from biodiesel from Jakarta and East Java.
