Abstract:
The purpose of this study is to experimentally investigate the performance and emission of compression ignition engine using biodiesel extracted from waste cooking oils (WCO), such as (falafel frying oil; origin from palm oil , chicken frying oil; origin from soybean oil), and fresh oils such as (soybean oil, olive oil), after produce biodiesel from WCO and fresh oils, will be blending with pure diesel in two percentage are B20 ( 20% biodiesel from each type, 80% pure diesel), B10 (10% biodiesel from each type , 90% pure diesel). The biodiesel blends were used as an alternative fuel for diesel engine. After that, they were compared to pure diesel B00 (0% biodiesel, 100%pure diesel) at engine variable load from (0-6 kW) at constant speed of (2000 RPM). For engine performance, (Brake power, brake specific fuel consumption, brake thermal efficiency) were analyzed. Also, for emissions, (, exhaust gas temperatures to indicate NOx) were analyzed. The results showed that pure diesel produces higher brake force (BP) than all biodiesel blends. The highest value for BSFC is for B20-F (20% biodiesel from falafel frying oil, 80% pure diesel) is equal (0.243426 gm/kW.s). The highest value for brake thermal efficiency BTE is for B10-S (10% biodiesel from soybeans oil, 90% pure diesel) is equal 27.6%. The B10-S produces the highest value of NOx. In addition, pure diesel produces higher emissions than all biodiesel blends. All biodiesel blends produce higher emissions than pure diesel.
