“…Biodiesel’s high oxygen content improves combustion, resulting in it producing such low levels of CO emissions . High levels of carbon monoxide (CO) emissions are normal for engines using diesel fuel because diesel contains significantly less oxygen than biodiesel . At a maximum load, the CPME30Eu70 with 10% DEE emits 20% less CO than diesel in TBC engines and 42% less than existing engines.…”

The optimum performance is achieved with CPME30Eu70 blended with 10% DEE in a TBC engine because DEE creates a relatively lean mixture with low viscosity that promotes improved fuel atomization and combustion.…”

The present experiment deals with the study of the effect of addition of diethyl ether (DEE) on the performance and emission characteristics of a thermal-barrier-coated (TBC) engine run on papaw (Carica papaya) and eucalyptus oil blends. The fuels studied were test blends, CPME30Eu70 (papaw methyl ester 30% and eucalyptus oil 70%) and CPME30Eu70 + 10% DEE, and diesel. Optimum results were obtained for CPME30Eu70 with DEE in a TBC engine. The addition of DEE creates a lean mixture, and its low viscosity, high cetane number, and volatility improve the performance of biofuel-powered engines. The investigation shows that the addition of 10% DEE gives the best results in brake-specific energy consumption (BSEC), brake-specific fuel consumption (BSFC), and brake thermal efficiency (BTE). The BTE of the DEE-adapted CPME30Eu70 blend was 32.2%, whereas for diesel it was 31.8%, which was 1.2% higher than that of CPME30Eu70 at normal mode of operation. The addition of DEE to CPME30Eu70 reduced BSEC and BSFC by 8.9 and 7.2%, respectively, compared to a non-coated engine powered by CPME30Eu70. The combination of DEE and CPME30Eu70 nominally decreased nitrogen oxide emissions. The carbon monoxide and hydrocarbon emissions of CPME30Eu70 after DEE addition were 0.195% vol. and 38 ppm, respectively, which were 13.3 and 5.1% lower than those for CPME30Eu70 powered by a compression ignition engine. The experiment found that adding DEE to CPME30Eu70 could improve its atomization and spray characteristics. Moreover, the performance and emission characteristics of the CPME30Eu70-powered engine were enhanced.

In this research, the CRDI engine characteristics were analyzed with the aid of exhaust gas recirculation rate (EGR) adoption fueled with ethanol blends. The test fuels were the various blends with ethanol, such as (10% of ethanol + 90% of diesel) E10D90 (20% of ethanol + 80% of diesel), E20D80, and (30% of ethanol + 70% of diesel) E30D70. From the results, it was revealed that performance characteristics were reduced when using a higher concentration of the alcohols mixed with diesel fuel. The blend E30D70 showed that brake thermal efficiency (BTE) without EGR drops by 3.8%, increased by 9.14% of BSFC, a 9.25% decrease in oxides of nitrogen emissions, and slightly decreased CO and HC emissions compared to baseline diesel operation at 60% load condition. The blend E10D90 with 20% EGR shows the highest BTE of 8.87% when compared with base fuel, due to proper fuel mixture taking place in the inlet manifold. The results indicate that the engine runs smoothly, and E30D70 has chosen an optimum blend. A further experiment was performed using E30D70 with different rates of exhaust gas recirculation system. The addition of exhaust gas recirculation with E30D70 in the common rail diesel engine exhibits oxides of nitrogen emission, but in contrast, it was noticed to have inferior performance characteristics and drastically decreased HC and CO emissions. The hydrocarbon emission decreased E10D90, E20D80, and E30D70 at 60% load condition by 21.42%, 37.38%, and 48.76%, respectively. The blends E10D90, E20D80, and E30D70 decreased carbon dioxide by 7.9%, 30.08%, and 31.98%, respectively. The maximum reduction of NOx emission was observed at about 51.06% at an EGR rate of 20% with E30D70.

“…One important aspect of this paper is that it considers turbocharged air temperature as one of the input parameters which has not been considered by other researchers so far and determines its optimum value for improved performance and low exhaust emissions. Literature also reveals that the optimisation techniques generally used for engine data analysis are response surface methodology (Kumar et al, 2016;Khoobbakht et al, 2016), Grey relational analysis (Karnwal et al, 2011;Jadhav, 2016;Deb et al, 2016;Etghani et al, 2013;Sakthivel et al, 2015), nonlinear regression (Maheswari et al, 2011), genetic algorithm (Alonso et al, 2007), Taguchi method (Karnwal et al, 2011;Jadhav, 2016;Ganapathy et al, 2009) and technique for order of preference by similarity to ideal solution (TOPSIS) (Deb et al, 2016;Etghani et al, 2013;Sakthivel et al, 2015). Roy et al (2014) did optimisation using Grey-Taguchi approach to calibrate trade-off characteristics of a dual-fuel engine.…”

Diesel engines convert chemical energy into mechanical energy generally with low efficiency. However, if these engines are operated at optimum levels of input parameters, they can produce power more efficiently with minimum harmful exhaust emissions. The current research work is carried out with an aim to determine these optimum levels of the input parameters. Four input parameters were selected and their optimum combinations were determined using Taguchi based technique for order of preference by similarity to ideal solution (TOPSIS) coupled with Entropy Weight method. Taguchi's L 25 orthogonal array was adopted to perform the experiments. All the test runs were carried out in random manner with three replicates of each to improve the accuracy of the experiments. The preference values (relative closeness of the distinct alternative to the positive ideal solution) predicted by Taguchi method and the values obtained by regression analysis, at optimum input parameter settings were compared and a good relationship was found between them.
