Abstract

Purpose The study aims to verify and establish the result of the most suitable optimization approach for higher performance and lower emission of a variable compression ratio (VCR) diesel engine. In this study, three types of test fuels are taken and tested in a variable compression ratio diesel engine (compression ignition). The fuels used are conventional diesel fuel, e-diesel (85% diesel-15% bioethanol) and nano-fuel (85% diesel-15% bioethanol-25 ppm Al2O3). The effect of bioethanol and nano-particles on performance, emission and cost-effectiveness is investigated at different load and compression ratios (CRs). The optimum performance and lower emission of the engine are evaluated and compared with other optimization methods. Design/methodology/approach The test engine is run by diesel, e-diesel (85% diesel-15% bioethanol) and nano-fuel (85% diesel-15% bioethanol-25 ppm Al2O3) in three different loadings (4 kg, 8 kg and 12 kg) and CR of 14, 16 and 18, respectively. The optimum value of energy efficiency, exergy efficiency, NOX emission and relative cost variation are determined against the input parameters using Taguchi-Grey method and confirmed by response surface methodology (RSM) technique. Findings Using Taguchi-Grey method, the maximum energy and exergy efficiency, minimum % relative cost variation and NOX emission are 24.64%, 59.52%, 0 and 184 ppm, respectively, at 4 kg load, 18 CR and fuel type of nano-fuel. Using RSM technique, maximum energy and exergy efficiency are 24.8% and 62.9%, and minimum NOX emission and % cost variation are 208.4 ppm and –6.5, respectively, at 5.2 kg load, 18 CR and nano-fuel. The RSM is suggested as the most appropriate technique for obtaining maximum energy and exergy efficiency, and minimum % relative cost; however, for lowest possible NOX emission, the Taguchi-Grey method is the most appropriate. Originality/value Waste rice straw is used to produce bioethanol. 4-E analysis, i.e. energy, exergy, emission and economic analysis, has been carried out, optimized and compared.

Taguchi-Grey法和RSM法对VCR柴油机在柴油-二乙醇-Al2O3纳米颗粒混合物上运行的参数优化：比较研究

目的本研究旨在验证和建立最适合可变压缩比（VCR）柴油机高性能、低排放的优化方法的结果。在本研究中，采用三种类型的试验燃料，并在可变压缩比柴油发动机（压燃式）中进行试验。所使用的燃料是传统柴油燃料、电子柴油（85%柴油-15%生物乙醇）和纳米燃料（85%柴油-15%生物乙醇-25ppm Al2O3）。研究了生物乙醇和纳米粒子在不同载荷和压缩比（CR）下对性能、排放和成本效益的影响。评价了该发动机的最佳性能和较低的排放，并与其他优化方法进行了比较。设计/方法/方法试验发动机由柴油、电子柴油（85%柴油-15%生物乙醇）和纳米燃料（85%柴油-15%生物乙醇-25 ppm Al2O3）在三种不同负载（4 千克，8 kg和12 kg）和CR分别为14、16和18。利用田口灰色方法确定了能源效率、火用效率、NOX排放和相对成本变化的最佳值，并用响应面法（RSM）技术进行了验证。结果采用田口灰色方法，最大能量和火用效率、最小相对成本变化%和NOX排放分别为24.64%、59.52%、0和184 ppm，分别为4 kg负载、18CR和燃料类型的纳米燃料。采用RSM技术，最大能量和火用效率分别为24.8%和62.9%，最小NOX排放和%成本变化为208.4 ppm和–6.5，分别为5.2 kg负载、18CR和纳米燃料。RSM被认为是获得最大能量和火用效率以及最小%相对成本的最合适的技术；然而，对于尽可能低的NOX排放，田口灰色方法是最合适的。创意/价值废弃的稻草被用来生产生物乙醇。进行了4-E分析，即能量、火用、排放和经济分析，并进行了优化和比较。
