A Comprehensive Study on the Effect of Dimethyl Carbonate Oxygenate and EGR on Emission Reduction, Combustion Analysis, and Performance Enhancement of a CRDI Diesel Engine Using a Blend of Diesel and Prosopis juliflora Biodiesel

This paper examines the combined effects of ignition improvers (DMC) and EGR on CRDI small single-cylinder diesel engine’s performance, combustion, emissions. In this experimentation, 20% (B20) optimal mix Prosopis juliflora oil biodiesel (PJOB) 5 ml dimethyl carbonate additive was used as test fuel. The fuel handling system factors such injection pressure set at 600 bar timing to 21 (bTDC) with a compression ratio 16 were considered for study. For trial, exhaust gas recirculated under various BMEP circumstances. performed without DMC conditions like (i) @ 0% EGR, (ii) + (iii) B20 (iv) engine power output. amalgamation additives reduces NOx smoke while increasing CO HC addition, improve thermal efficiency slightly. overall clubbing rate indicates better performance selected than six-hole conventional mechanical system. outcome work clearly demonstrates that both blend show optimum values BTE, BSFC, EGT 32.93%, 0.27 kg/kw·hr, 310.89°C, which is closer diesel.
