Transesterified Curcas Oil Blends for Farm Diesel Engines

Yukitsugu Ishii; Ryuzo Takeuchi

ABSTRACT PERFORMANCE, 50-h continuous, and starting tests were conducted using transesterified curcas oil. No. 2 diesel fuel, and their blends in two small precombustion chamber type diesel engines. Compatibility of engine parts to curcas oil was examined by submerging the parts in engine oil for 130 days. Blended oil produced superior thermal efficiency and fuel consumption equivalent to No. 2 diesel. There was a slight reduction in black smoke concentration when operating on transesterified curcas oil and its blended oils. The CO and HC concentrations from transesterified curcas oil increased at light loads and was equivalent to No. 2 diesel at full load. The HC concentrations of No. 2 diesel increased greatly at overload, while those of transesterified curcas oil decreased..
