Experimental analysis reveals optimized biodiesel blend reduces emissions and improves efficiency in CRDi engines.

This research aims to analyze the effects of microwave-assisted biodiesel synthesis on engine performance and emissions.
Synthesize biodiesel using alkali-catalyzed transesterification of Simmondsia chinensis oil.
Stabilize biodiesel with pyrogallol antioxidant to enhance fuel durability.
Test blends with varying compression ratios and exhaust gas recirculation rates in a modified CRDi diesel engine.
The ternary biodiesel blend at CR 20:1 with 15% EGR showed a 2.31% improvement in brake thermal efficiency.
NOx emissions were reduced by 29%, and smoke opacity decreased by 16.2% compared to conventional diesel.
Higher emissions of HC and CO observed at lower CRs and higher EGR rates due to incomplete combustion.

Ashwin et al. (2026) studied this question.
