A Numerical Investigation of the Effects of Piston Bowl Geometry and Spray Angle on Combustion, Performance and Emission of a Diesel Engine

Energy Science &Engineering, EarlyView.
A piston bowl's design and spray angle improve air‐fuel mixing, resulting in more complete combustion and higher efficiency. Ansys Forte 2023 R1 a CFD software was used to analyze the effects of five combustion chamber geometries of cylinder, modified re‐entrant, re‐entrant, double‐stepped, and stepped on engine performance, combustion, and emission ...

Model-Based Control for Dual-Fuel Engines

Frontiers in Mechanical Engineering, 2020
The dual-fuel engine (DFE) has been focused on in order to improve its efficient use of natural gas. It has been reported that in DFE the combustion efficiency of the natural gas decreases at a low load.

DIESEL SOOT COMBUSTION WITH PEROVSKITE CATALYSTS

Chemical Engineering Communications, 2014
Diesel soot emissions from stationary or mobile sources can be reduced through physical trapping in particulate filters until periodical in situ combustion takes place. This study focuses on the development of several perovskites for the catalytic combustion of diesel particulates in multifunctional catalytic reactors.

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

High‐Throughput Geocoding to Assess Short‐Term Air Pollution in Correlation With Mortality in a French Cancer Patient Cohort

International Journal of Cancer, EarlyView.
Although chronic air pollution exposure is linked to lung cancer mortality, the short‐term effects of fluctuating air quality on overall cancer mortality remain uncertain. Here, the authors applied geomatics and machine‐learning models to retrospectively examine possible associations between 31‐day pollution exposure and mortality in a French cancer ...

Environmental chemicals and the tumor immune microenvironment

iMeta, EarlyView.
Impact of representative environmental chemicals on tumor immune microenvironment (TIME). Representative environmental chemicals are ubiquitously distributed across air, soil, aquatic systems, and biota. These toxicants enter the human body via multiple exposure routes, including inhalation, dietary intake, and dermal absorption, subsequently ...

The Effect of Combustion Swirl on the Combustion in a Diesel Engine

Bulletin of JSME, 1959
In order to investigate the effect of the timing of swirl creation on the combustion process in a Diesel engine, varying amounts of fuel were injected from two sets of fuel-injection equipments into the main and auxiliary combustion chambers respectively at different timings.
