Air Fuel Control System
Years ago, before exhaust emissions were a concern, the natural gas engines used mainly by the natural gas industry were designed to run with excess air. The air-fuel ratio controllers were mechanical devices that were not very accurate and sometimes not even used. These engines ran very well with 5% to 20% excess air. The air-fuel ratio would often vary with load and as long as the engines would ...

Catalytic decomposition of NO2 over a copper-decorated metal-organic framework by non-thermal plasma
Nitrogen oxide (NOx) causes significant impacts on the environment and human health, and nitrogen dioxide (NO2) is the most toxic and prevalent form of NOx in the atmosphere. Its removal and catalytic degradation into non-harmful species (i.e., N2) are thus important challenges. A great deal of effort has been devoted to developing catalysts for deNOx processes with a focus on NO reduction from ...

The problem of NOx emissions
The problem of NOx emissions The problem with Nitrogen compounds (NOx) emissions is that they contribute to generating the greenhouse effect. For example, N2O causes 300 times more damage than CO2. In addition, NOx combines with the humidity of the air in the atmosphere and is the cause of acid rain and is therefore very dangerous for the environment. ...
