Research on the effects of negative valve overlap duration on the combustion and emission of methanol, ethanol, isopropanol, and n-butanol in a spark induced compression ignition (SICI) engine by experiments and Artificial Neural Networks

Fuel Processing Technology
In order to achieve the carbon neutrality goal, it is urgent to improve the thermal efficiency of engines and the application of carbon neutral fuels. Due to the low emissions and renewability of alcohols, which are considered as potential alternative ...

Investigation of Auto-ignition of Several Single Fuels

MATEC Web of Conferences, 2014
HCCI operating principals have been widely investigated yet the uncontrollable combustion of HCCI is the major obstacle in its development. This paper is trying to increase the understanding on the auto-ignition and combustion process of several fuels to

A Microscopic Analysis of Premixed Hydrogen-Oxygen Auto-ignition [PDF]

, 2016
Combustion is a complex problem involving multi-stage chemical reactions and multi-scale physics. The microscopic process of chemical reactions has obvious stochastic character and may bring important influence to combustion phenomena both locally and ...

Recognition of Spatiotemporal Feature Images of Zero‐Sequence Voltage for Single‐Phase High‐Impedance Ground Faults Under Complex Conditions

High Voltage, EarlyView.
ABSTRACT Diagnosing high‐impedance ground faults (HIGFs) in distribution networks is extremely challenging because high transition resistance significantly reduces electrical signal strength and unpredictable initial fault phase angles coupled with asymmetric voltage disturbances often lead to misclassification.

Analysis of Diesel Knock for High-Altitude Heavy-Duty Engines Using Optical Rapid Compression Machines

Energies, 2020
In high altitude regions, affected by the low-pressure and low-temperature atmosphere, diesel knock is likely to be encountered in heavy-duty engines operating at low-speed and high-load conditions.

The Gender of Fossil Fuels: Oil and Domestic Perils in Mandate Palestine

Gender &History, EarlyView.
ABSTRACT This article explores the gender dynamics behind the rise of kerosene – an oil derivative – as the main domestic fuel in Mandate Palestine. It argues that these dynamics were constitutive in determining who began to use oil, where and for what purposes, in turn demonstrating that women in Palestine were the promoters and targets of a campaign ...

COMMON SENSE LAW: Making Right/s in the Liberal City

International Journal of Urban and Regional Research, EarlyView.
Abstract This article, co‐authored by encampment and university scholars, is concerned with how homeless persons challenge rightlessness. We do so by advancing a conceptual framework of common sense law, arguing that such contestations take place not only in courtrooms but also in the lived spaces of homelessness.
