Fuel Sprays for Premixed Compression Ignited Combustion - Characteristics of Impinging Sprays

Exploring the Impact of Al2O3 Additives in Gasoline on HCCI-DI Engine Performance: An Experimental, Neural Network, and Regression Analysis Approach

“…Although HCCI combustion technology has demonstrated its effectiveness in lowering NOx emissions and improving thermal efficiency, researchers have encountered various challenges when operating HCCI engines under high loads and speeds, features like increased banging, greater HC and CO emissions, and issues with the air and gasoline mixture’s nonhomogeneity in the intake manifold . In a quest to address these quandaries, scholars have delved into an array of techniques, such as implementing exhaust gas recirculation (EGR), wielding turbocharging/supercharging, increasing the fuel’s injection pressure, fine-tuning the compression rate, and augmenting suction air to magnify the power of HCCI engines. − …”

Experimental investigation, optimization and ANN model prediction of a gasoline premixed waste cooking oil fueled HCCI–DI engine

“…In 2002, Zhao et al experimentally investigated a four-stroke multi-cylinder gasoline engine in the HCCI combustion process [12]. Further, researchers reported that the operations at higher loads and at higher speeds, emissions having higher HC (hydrocarbon) and CO (carbon monoxide), higher knocking and the inhomogeneity in the mixture at inlet manifold were some of the challenges in the HCCI combustion [13].…”
