Hydrogen‐Enriched Tri‐Fuel Combustion for Low‐Carbon Engines at Medium Engine Load: A Comprehensive CFD Analysis

Energy Science &Engineering, EarlyView.
CFD analysis of a diesel–CH4–H2 tri‐fuel engine shows that increasing hydrogen energy share (HES) enhances mixing and accelerates combustion, improving pressure, efficiency, and reducing CO and soot. At 60% HES, ISFC improves 26.2%, soot drops 95%, while NOx increases due to higher temperatures. ABSTRACT The global commitment to achieve net‐zero carbon

Recent Advances in Ozone-Assisted Combustion for Sustainable Thermal Engines

Energies
Recent advances in ozone-assisted combustion for both compression ignition and spark ignition engines are discussed. Ozone, which can be produced by an electrical discharge in air or pure oxygen, decomposes at high temperature to yield highly oxidizing ...

The Belief–Desire Appraisal Theory of Emotion

Pacific Philosophical Quarterly, EarlyView.
ABSTRACT I introduce the Belief–Desire Appraisal Theory of Emotion (BDA). BDA makes three main claims: (a) Emotions are psychological episodes whose paradigmatic instances are constituted by coordinated changes in appraisals, action tendencies, bodily responses, and subjective feelings; (b) appraisals—which are rapid, low‐level evaluations of ...

Insights into the underlying reaction kinetics of gasoline–ethanol interactions and their effects on the auto-ignition characteristics of gasoline/ethanol blends

Applications in Energy and Combustion Science
Ethanol-blended gasolines show enhanced anti-knock behavior in spark-ignition engines. Fundamental experimental investigations on their auto-ignition behavior are however scarce in the literature.

A Study on Homogeneous Charge Compression Ignition Gasoline Engines.

JSME International Journal Series B, 2003
A new engine concept consisting of HCCI combustion for low and midrange loads and spark ignition combustion for high loads was introduced. The timing of the intake valve closing was adjusted to alter the negative valve overlap and effective compression ratio to provide suitable HCCI conditions.

Rethinking Political Islam in Iran: Contestation, Authority, and Reform

Middle East Policy, Volume 33, Issue 3, Autumn (Fall) 2026.
Abstract Political Islam in Iran is frequently portrayed in Western scholarship and policy discourse as a unified and rigid ideological system rooted in the 1979 Islamic Revolution. However, this article contends that it operates as a plural and internally contested field in which state‐directed, reformist‐clerical, and civic interpretations compete ...
