Results show that particle size and the initial temperature have significant impact on NO and N2O formation, whereas pressure shows a less significant effect. NOX formation mechanism pathways show that the oxidation of ammonia has a significant influence on NO production, while the reduction of NO ...
N2O causes an increase in greenhouse gases. In addition to these environmental impacts, nitrogen oxides have a negative effect on human health by impairing respiratory function. Nitric oxide enters the alveoli of the lungs and dissolves in the bloodstream, resulting in a decrease of the amount of...
The effect of the combustion-air/gasification-air ratio (CA/GA: 2.8, 3.0, and 3.2) on the energy and environmental performance of a TLUD biomass cookstove was assessed. The experimental characterization is carried out by analyzing two control volumes: (1) the thermal efficiency of the cookstove...

This paper focuses on criteria pollutants. Emissions from ICE vehicles also include carbon dioxide (CO2), a greenhouse gas that is the main combustion product of carbon-based fuels. Vehicle CO2emissions are regulated around the world and are reduced by improving the fuel efficiency of the vehicles...
(CO2) by 7.8%. One notable advantage of the B30+DPA100 blend is the significant decrease in NOx emissions. Additionally, the cylinder pressure for B30+DPA100 has been lowered by 4.93% compared to B30. On the other hand, the net heat release rate (NHR) has experienced a 1.72% increase....
It creates environmental problems such as acid rain, photochemical smog, ozone layer depletion, Greenhouse effect (indirect impact), and ecological toxification [3], [4], [5]. Understanding the photochemical transformations of nitrogen oxides (NO, NO2, NO3) in urban air was recently reviewed by...
