Looking at New Concepts for Ultra-Low Emission Diesel Combustion System

Design, Application, Performance and Emissions of Modern Internal Combustion Engine Systems and Components, 2002
The DI (Direct Injection) Diesel engine, which is inherently capable of achieving very low CO2 emissions, is affected by PM (Particulate Matter) that is the typical emission of turbulent diffusion flames and has the drawback of high NOx (nitrogen oxides) emissions.

Highly Efficient, Ultra‐Low Energy Consumption Process for Phenol Wastewater Treatment with Ultra‐Low Carbon Emission

CLEAN – Soil, Air, Water, 2013
AbstractPhenol is one of the main pollutants in phenol wastewater and has been proved non‐biodegradable. In this study, based on strongly ring‐opening capability of boron doped diamond film electrode, a highly efficient and energy‐saving method with ultra‐low carbon emission is established through a combination of electrochemical oxidation and ...

Measurements and Modeling of the Flow Field in an Ultra-Low Emissions Combustor

44th AIAA Aerospace Sciences Meeting and Exhibit, 2006
The flowfield of a novel combustor design that can operate stably even at high flowrates and very lean conditions is studied. This Stagnation Point Reverse Flow (SPRF) combustor consists of a central injector at the single open end of a cylindrical chamber, with the injector inlet area much less than the open area of the combustor through which the ...

L4–Engine Development for a Super Ultra Low Emissions Vehicle

SAE Technical Paper Series, 2000
<div class="htmlview paragraph">HONDA has developed technology to fulfill the strictest emissions standards to date. That is, we have developed the technology necessary to satisfy the state of California's SULEV (LEV–II) regulations. We were able to move from the conventional 600–cell, 4.3mil three–way catalyst to a 1200–cell, 2.0mil catalyst ...

Impact of ultra low thermal inertia manifolds on emission performance

SAE Technical Paper Series, 2007
<div class="htmlview paragraph">In order to fulfill the more and more stringent emission levels (Euro V, SULEV…), catalytic converter light-off time has to be reduced as much as possible. Consequently, all the parts upstream of the catalytic converter have to be designed in order to minimize the gas heat loss.</div> <div class="htmlview ...

Ultra-low-threshold field emission from conjugated polymers

Nature, 1998
Field-emission displays contain materials that emit electrons when charged to a low (negative) potential; the electrons excite light emission from phosphor screens. These devices have the potential to provide flat-panel visual displays with good picture quality at low power consumption and low cost1.

Potential of oxymethylenether-diesel blends for ultra-low emission engines

Fuel, 2017
Abstract In the race to counteract global warming, fossil fuel dependency and urban air pollution, it is clear that vehicle emissions have to be reduced considerably. A pathway out of today’s limitations in engine technology is synthetic fuel. In particular, oxymethylenether (OME) is an attractive candidate due to its soot free combustion.

Selected Topics in Ultra-Low Emissivity Alpha-Particle Detection

IEEE Transactions on Nuclear Science, 2013
In an effort to better understand the contribution of terrestrial protons to the counter background, we have developed a model to examine the production of protons, within an ionization counter from the interaction of incident neutrons on the counter material.
