Octane Index Applicability over the Pressure-Temperature Domain

Energies, 2021
Modern boosted spark-ignition (SI) engines and emerging advanced compression ignition (ACI) engines operate under conditions that deviate substantially from the conditions of conventional autoignition metrics, namely the research and motor octane numbers

Development and Experimental Validation of an Adaptive, Piston-Damage-Based Combustion Control System for SI Engines: Part 2—Implementation of Adaptive Strategies

Energies, 2021
This work focuses on the implementation of innovative adaptive strategies and a closed-loop chain in a piston-damage-based combustion controller. In the previous paper (Part 1), implemented models and the open loop algorithm are described and validated ...

Knock, Knock: Who’s There? [PDF]

Circulation, 2013
It has become apparent that major sources of reactive oxygen species (ROS) in mammalian cells are the NADPH oxidases. These multimeric enzymes are composed of membrane-bound catalytic subunits, or Nox enzymes, and a small docking subunit called p22phox.

Knock combustion characteristics of an opposed‐piston two‐stroke gasoline engine

Energy Science & Engineering, 2022
The spark plug of an opposed‐piston two‐stroke (OP2S) gasoline engine is arranged on the side wall of the cylinder liner, far from the center of the combustion chamber; the ignition core of the mixture is offset, the flame propagation distance is ...

Deep Learning for Knock Occurrence Prediction in SI Engines

Energies, 2022
This research aims to predict knock occurrences by deep learning using in-cylinder pressure history from experiments and to elucidate the period in pressure history that is most important for knock prediction. Supervised deep learning was conducted using

Effect of Spark Ignition Timing and Water Injection Temperature on the Knock Combustion of a GDI Engine

Energies, 2020
A turbocharged downsizing spark ignition (SI) engine cooperating with an in-cylinder direct injection technology is one of the most effective ways to improve the power and economy of gasoline engines. However, engine knock has limited the application and
