Performance analysis of Single-Cylinder CI Engine with Turmeric Leaf Oil Biodiesel at Different Operating Conditions

Abstract

Biodiesel, made from vegetable oils, non-edible oils, and animal fats, is a promising diesel alternative. The performance of a single-cylinder diesel engine using turmeric leaf oil biodiesel is examined in this study. Three biodiesel blends—B10, B20, and B30—were tested against diesel fuel. The highest brake thermal efficiency (BTE) of 24.84% and the lowest brake-specific fuel consumption (BSFC) of 0.28 kg/kWh were achieved using diesel fuel at 600 bar injection pressure, 18 compression ratio, and full engine load. With the same operating conditions, biodiesel blends B10 (23.84% and 0.29 kg/kWh), B20 (23.38% and 0.32 kg/kWh), and B30 (23.22% and 0.34 kg/kWh) had BTE and BSFC values.
