Grey-Taguchi and ANN based optimization of a better performing low-emission diesel engine fueled with biodiesel

M. Gul et al.

Summary: This study applies the L9 (3(3)) Orthogonal Array of Taguchi design to optimize the usage of waste cooking oil based pure biodiesel and biodiesel blended with neat diesel in a DI-CI diesel engine. By optimizing the nature of fuel, engine speed, and load, the study aims to reduce smoke and NOx emissions, and improve engine heat release, cylinder pressure, and brake power.

Prediction of the performance and exhaust emissions of ethanol-diesel engine using different neural network

Gongping Mao et al.

Summary: The objective of this study is to predict the performance and exhaust emissions of an ethanol-diesel engine using multiple neural network models. The results indicate that all four networks perform well in predicting the target engine's exhaust emissions and performance, with radial basis network demonstrating the best prediction effect.

Effect of ethanol-gasoline blends on SI engine performance and emissions

Mortadha K. Mohammed et al.

Summary: The negative effects of traditional engine fuels on climate change have led to a high level of competition in finding alternative fuels that are more environmentally friendly. Alcohol fuels, particularly ethanol, have been found to be practical for blending with traditional engine fuels like gasoline. Research has shown that blending ethanol with gasoline can increase power, efficiency, and reduce harmful exhaust gases. However, ethanol may have a negative impact on volumetric efficiency, while also improving power and efficiency as its concentration increases.

Experimental study on spray characteristics, combustion stability, and emission performance of a CRDI diesel engine operated with biodiesel-ethanol blends

Limin Geng et al.

Summary: The study found that adding ethanol to biodiesel improves spray characteristics and combustion performance in diesel engines. At low loads, peak cylinder pressures (PCPs) of BE blends are higher than diesel, while peak heat release rates (PHRRs) are also higher. However, at medium-high loads, PHRRs decrease and emissions decrease with increasing ethanol blending ratio.
