Experimental investigation on a diesel engine operated in RCCI combustion mode [PDF]

AIP Conference Proceedings, 2019
Low Temperature Combustion (LTC) concepts have been investigated in many recent studies, aiming to improve engine efficiency and minimize pollutant emissions. One of the most promising techniques is represented by the Reactivity Controlled Compression Ignition (RCCI), that can be obtained combining a low reactivity fuel (such as gasoline, natural gas ...

Enhancing Public Safety in Eswatini: A Machine Learning–Driven Predictive Policing Model

Human Behavior and Emerging Technologies, Volume 2025, Issue 1, 2025.
Public safety remains a critical concern in Eswatini, as it prevents crime, reduces delayed response mechanisms, and optimizes police resources. This study applied machine learning techniques in predictive policing within the Kingdom of Eswatini (formerly Swaziland) to improve proactive law enforcement strategies and public safety.

Machine Learning–Based Prediction and Analysis of Engine Performance for a Direct‐Port Injection Compressed Natural Gas Fueled Engine

Journal of Combustion, Volume 2025, Issue 1, 2025.
Compressed natural gas (CNG) is one of the most potential alternative fuels for internal combustion engines (ICEs). Investigation of injection strategies is crucial to improve CNG engine performance and extend flammability limit, especially for direct‐port combined injection (DI‐PI) CNG engine.

A combustion phasing control-oriented model applied to an RCCI engine

IFAC-PapersOnLine, 2018
[EN] Low temperature combustions such as Reactivity Controlled Compression Ignition (RCCI) have been shown to be a promising way to reduce pollutants at the exhaust, i.e. NOx and soot emissions, and increase the thermal efficiency of future engines. However, such concepts are subject to substantial control sensitivity, e.g.
