For decades, combustion researchers and engine companies have been seeking to understand how these gases are produced during combustion so that they can find ways to reduce them. Now researchers have ...

Exhaust NOx and particulate measurements were obtained at equivalent operating conditions in a direct-injection compression ignition engine for diesel and diethyl ether fuel. Particulate levels for ...

Figure 1: NO-dependent activation of H-NOX protein. The 'sidedness' of the NO complex (distal vs. proximal) could have profound biological consequences on the signal half-life. Return of the distal NO ...

Why is NOx such a major concern in the U.S. and elsewhere? NOx consists of roughly 90% to 95% NO and perhaps 5% to 10% NO 2. Those associated with fossil fuel fired boilers and other furnaces are from ...

Utility boilers have long been a cornerstone of power generation; however, increasing environmental pressures drive continuous development in combustion technology and emission control. Recent ...

Conventional fossil fired boilers across the globe are being subjected to ever more stringent emissions limitations, despite the majority of those installations having been built during an era when ...

Air pollution in China has exhibited noticeable changes over the past 30 years, shifting from point-source pollution (around factories and industrial plants) in the 1980s to urban pollution in the ...

Dilute operation of a SI engine offers attractive performance incentives. Lowered combustion temperatures and changes in the mixture composition inhibit NOx formation and increase the effective value ...

Nitrogen Oxides (NOx) emissions are regulated not only because they are highly reactive gases, but also due to the fact they react with VOC and Sunlight to form ground level ozone and smog. The ...

Given the significant environmental concerns associated with emissions from energy systems, effective mitigation strategies are crucial to a sustainable future. This is particularly relevant ...

Nitrogen oxides (NOx) are some of the most significant pollutants in our atmosphere — they contribute to the formation of smog, acid rain and ground-level ozone. Because of this, combustion ...
