摘要

The current investigational research is to enhance the operational features of Calophyllum inophyllum biodiesel (CIBD) fuelled diesel engine through DiEthyl Ether (DEE) and Iso-Butanol (IB) as secondary fuel along with PCCI strategy. Premixing of DEE and IB was carried out at two different conditions, in terms of 10% and 20% energy share of primary injected fuel B20 (20% CIBD + 80% diesel). The Response Surface Methodology Design of Experiments (DoE) was employed to enhance engine performance, emissions, and combustion characteristics. At all loaded conditions, the premixing of DEE and IB increased Brake Thermal Efficiency (BTE) and decreased Brake-Specific Fuel Consumption (BSFC) in comparison with B20. IB premixing showed higher BTE and lower BSFC than DEE at peak load. Additionally, the combustion characteristics were enhanced by IB premixing. Under all conditions, IB demonstrated reduced emissions of CO, NOx, and CO2 in comparison with DEE premixing. However, HC emissions got elevated. The optimal parameters of 60% load and B20 + 10IB yielded better engine working characteristics. The adaptation of the Premixed Charge Compression Ignition (PCCI) strategy in conventional CI engines is considered a sustainable technology to reduce emissions without sacrificing engine performance, especially when compared to conventional combustion.
