EMISSION PERFORMANCE ANALYSIS OF DIESEL BLENDED WITH WASTE PLASTIC OIL

This work is investigation about the engine performance and emission of a single-cylinder variable compression ignition engine working on diesel blended with Waste Plastic Oil (WPO) under various load conditions. The blends containing 10%, 20%, 30%, 40%, and 50% WPO by volume were examined with pure diesel (D100). Results show a gradual decrease in Brake Thermal Efficiency (BTE) with increasing WPO volume while Exhaust Gas Temperature (EGT) rose with higher blends, peaking at 337 °C for D50WPO50.The emission of CO₂ found to be less by 33.3% at the highest blend, while CO and hydrocarbon (HC) increased by 32.7% and 51.3%. Emission of Nitrogen oxides (NOₓ) showed a non-linear trend, initially decreasing at D80WPO20. D80WPO20 is the best-balanced blend keeping in mind optimum performance and emission. The findings are aligned with the past studies conducted in same fields
