Experimental investigation of SI engine characteristics using Acetone-Butanol-Ethanol (ABE) - Gasoline blends and optimization using Particle Swarm Optimization

P. Dinesha et al.

Summary: This study experimentally investigates the characteristics of spark ignition (SI) engine using gasoline blended with Acetone-Butanol-Ethanol (ABE) as hydrogen and oxygen carriers. A multi-objective optimization technique, Particle Swarm Optimization (PSO), is used to optimize the engine performance and emission parameters. The results show that by controlling the blend percentage and speed, the engine can achieve optimal combustion efficiency and emission performance.

Experimental study on combustion and emission of an SI engine with ethanol/gasoline combined injection and EGR

Zhe Zhao et al.

Summary: This study shows that the cooperation of EGR and EDI can improve the performance of spark ignition engines and reduce emissions. Under lean burn conditions, specific ratios of EGR and EDI can significantly improve the combustion and emission characteristics of the engine. Ethanol has a higher oxygen content and faster laminar flame speed, while EGR can reduce pumping and throttling losses and enhance the positive effects of ethanol on combustion and emissions.

An Experimental and Kinetic Modelling Study on Laminar Premixed Flame Characteristics of Ethanol/Acetone Mixtures

Yangxun Liu et al.

Summary: Research on the burning characteristics of ethanol-acetone blends is important for understanding the combustion phenomena of alternative fuels. The study found that as the ethanol content in the mixtures increases, the laminar burning velocities also increase. The detailed chemical kinetic mechanism used for simulation indicated that the reaction C2H2+H(+M)C2H3(+M) is the key reaction in the burning process.

A Study of the Impact of Methanol, Ethanol and the Miller Cycle on a Gasoline Engine

Luke Oxenham et al.

Summary: This study focused on the optimization of the Miller cycle, methanol, ethanol, and turbocharging when applied to a high-performance gasoline engine, with a particular emphasis on emission reduction and performance improvement. The results showed that these technologies can have compounding effects when applied cooperatively, with biofuels achieving significant reductions in NOx and CO emissions alongside efficiency improvements. The use of biofuels exclusively was found to be feasible, albeit with a power penalty, and the Miller cycle was found to improve engine efficiency and power output.
