Abstract
Ketersediaan bahan bakar secara umum dan bahan bakar dalam pengoperasian motor diesel secara khusus kini semakin berkurang. Disamping itu, permasalahan lingkungan terkait global warming, salah satunya tentang polusi udara juga sudah mengkhawatirkan. Pemanfaatan minyak goreng bekas sebagai bahan biodiesel dapat menjadi salah satu jalan keluar krisis bahan bakar. Penambahan teknologi Exhaust Gas Recirculation (EGR) juga bisa memberikan jawaban dalam mengatasi polusi udara. Penelitian ini akan membahas pemanfaatan minyak jelantah atau Waste Cooking Oil (WCO) dan penambahan Exhaust Gas Recirculation (EGR). Analisa yang dilakukan meliputi peforma, hasil proses pembakaran serta emisi dalam NOx penggunaan bahan bakar biodiesel. Penggunaan biodiesel WCO dengan penambahan sistem EGR, menghasilkan peforma lebih baik dari bahan bakar konvensional dengan nilai SFOC sebesar sama di angka 301gr/kWh, biodiesel dengan sistem EGR mempunyai ignition delay yang lebih singkat 0,19 ms (millisecond) dari bahan bakar biasa. Penambahan EGR menyebabkan ignition delay semakin panjang namun combustion pressure peak yang lebih rendah. Emisi biodiesel dengan penambahan EGR maksimal sebesar 30% adalah 3,3 gr/kWh, lebih rendah hingga 4,9 gr/kWh dari biodiesel tanpa EGR pada putaran 2200RPM dan beban 100%.
=================================================================
The availability of both fuel for the household and fuel for diesel motor operation in particular is now diminishing. In addition, environmental issues related to global warming such as air pollution is also alarming. Utilizing used cooking oil as a biodiesel material can be an alternative way to reduce fuel crisis. The addition of Exhaust Gas Recirculation (EGR) technology can also provide an answer in overcoming air pollution. This research discusses the utilization of waste cooking oil (WCO) and the addition of Exhaust Gas Recirculation (EGR). The analyzes were conducted including performance, combustion process results and emissions in NOx of biodiesel fuel usage. The use of WCO biodiesel with the addition of EGR system, produces better performance than conventional fuel with SFOC value equal to 301gr / kWh, biodiesel with EGR system has a shorter ignition delay of 0.19 ms (millisecond) than ordinary fuel. The addition of EGR causes longer ignition delay and lower peak combustion pressure. Biodiesel emissions with a maximum 30% EGR addition were 3.3 g / kWh, lower to 4.9 g / kWh from biodiesel without EGR at 2200RPM and 100% load.
