摘要

这项工作的重点是研究压缩比（CR）对燃用柴油（80%）和热解油（20%）混合物的柴油发动机运行特性的影响，该混合物来源于标准条件下的Bael脱油滤饼。发动机在三个CR下运行，即18:1（较高）、17.5:1（标准）和16:1（较低）。对于满负荷混合燃料运行，随着CR从17.5增加到18，制动热效率（BTE）提高了5%，制动比能耗（BSEC）降低了3%。在高CR下，与峰值负荷下的柴油相比，混合燃料的一氧化碳（CO）和未燃碳氢化合物（HC）分别降低了58.3%和38.5%。混合燃料在峰值负荷和CR为18:1时的氮氧化物排放量（NOx）增加了25.7%。试验结果表明，发动机在CR 18:1时可以达到最佳性能。

Investigations on diesel engine characteristics using waste biomass Pyrolysis oil: A study on the effect of compression ratio

This work is focussed at studying the compression ratio (CR) effect on the operating characteristics of a diesel engine fuelled with diesel (80%) and pyrolytic oil (20%) blend, derived from Bael de oiled cake at standard conditions. Engine was operated at three CR’s namely 18:1 (higher), 17.5:1 (standard) and 16:1 (lower). For the blended fuel operation at full load, the brake thermal efficiency (BTE) improved by 5% and brake specific energy consumption (BSEC) diminished by 3% as the CR increased from 17.5 to 18. At high CR, the carbon monoxide (CO) and unburnt hydrocarbon (HC) were lowered by 58.3% and 38.5% respectively for blended fuel when compared to diesel at peak load. The nitrogen oxides emission (NOx) increased by 25.7% for blended fuel at peak load and CR of 18:1. On the whole the experimental results suggest that optimum performance of the engine can be attained at CR 18:1.
