Homogenous Charge Compression Ignition (HCCI) Engines [PDF]

, 2013
With stricter regulations imposed by the European Union and various governments, it is not surprising that the automotive industry is continuously looking for alternatives to Spark Ignition (SI) and Compression Ignition (CI) Internal Combustion (IC) engines.

A Mechanism of Thermal Ignition Appearance in Homogeneous Charge Compression Ignition Process

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2006
The transition process from cool flame to thermal flame in homogeneous charge compression ignition is discussed in this paper. It was confirmed in HCCI engine experiments using dimehtyl ether, n-heptane and n-decane as fuels that the heat release rate during transition process from the cool ignition to the thermal ignition exhibits linear shape in an ...

Heat Transfer Fluids as Co‐Diluents in Localized High‐Concentration Electrolytes for High‐Rate Lithium Metal Batteries With Enhanced Safety

Angewandte Chemie International Edition, EarlyView.
Two fluorinated ethers, commonly used as heat‐transfer fluids, are explored as co‐diluents in localized high‐concentration electrolytes (LHCEs) for lithium metal‐based batteries. The best‐performing ternary diluent blend boosts ion mobility and cuts overvoltages, thereby improving Coulombic efficiency and cycle life at ≥1 mA cm−2 in zero‐excess pouch ...

Antistatic High‐Density Polyethylene (HDPE)/Conductive Carbon Black (CCB) Composites for Automotive Parts: Influence of CCB Structure and Molding Technique

Journal of Applied Polymer Science, EarlyView.
Antistatic performance in HDPE/conductive carbon black composites is governed not only by filler structure but also by processing. Injection molding induces surface resistivity through skin–core effects, whereas compression molding favors conductive networks.

English teachers' journeys since the 2020 Iteration of Black Lives Matter

British Educational Research Journal, EarlyView.
Abstract The 2020 resurgence of Black Lives Matter (BLM) mobilised students in England to demand greater representation of racially minoritised voices in English curriculums—a call highlighted by stark inequity: just 1.5% of GCSE texts studied are by racially minoritised authors, despite racially minoritised students comprising 38.0% of the student ...

Modeling of homogeneous charge compression ignition (HCCI) of methane [PDF]

, 1997
The operation of piston engines on a compression ignition cycle using a lean, homogeneous charge has many potential attractive features. These include the potential for extremely low NO{sub x} and particulate emissions while maintaining high thermal efficiency and not requiring the expensive high pressure injection system of the typical modem diesel ...
