State the four main pollutants emitted by an internal combustion engine?
Carbon Monoxide, Nitrogen Monoxide, Hydro Carbons, Nitrogen Dioxide
What are pollutants emitted by an internal combustion engine?
carbon monoxide, due to improper combustion Hydrocarbon and nitrogen oxides Also, if the fuel contains sulfur, oxides of sulfur
What materials make nitric acid?
H2NO3hydrogennitrogenoxygenCombine nitrogen and oxygen at high temperature and pressure (as in internal combustion engine) to make nitrogen dioxide (NO2). Dissolve nitrogen dioxide in water to get nitric acid.
What are the role of combustion engine in nitrogen fixation and atmospheric pollution?
The combustion engine releases a lot of chemicals and smoke into the air. This raises nitrogen in the atmosphere and pollutes the air.
What temperature does nitrogen gas burn?
Nitrogen burns to form Nitrogen Dioxide at about 2200F. It is an exothermic reaction, meaning it will produce heat sufficient to sustain itself if the heat is confined, for example in an internal combustion engine.
Why is nitrogen dioxide not formed in a car engine?
because of combustion
If you wanted to make nonpolluting fuel gas how would you do it?
The closest to a non-polluting gas would be hydrogen as the principle combustion product would be water. ANy flammable gas with carbon, sulfur or nitrogen would produce contaminants. The gas would have to be combusted in a low temperature environment like a fuel cell to avoid the formation of nitrogen oxides in the combustion chamber. If a high temperature system (internal combustion engine) is considered the combustion air would have to be nitrogen free - pure oxygen or an inert gas/nitrogen free/oxygen mix
Why does nitrogen and oxygen react in a car engine?
Nitrogen and oxygen can react to form oxides of nitrogen. The reaction can occur whenever a combustion reaction takes place in the presence of nitrogen. It could take place in a car engine because it is where fuel combusts and the temperature within engines can be high. The products formed are NO (nitric oxide) and NO2 (nitrogen dioxide) which are of harm to the environment.
What is the combustion chamber temperature in diesel engine?
180o C
What is the temperature inside the combustion chamber of a jet engine?
The temperature inside the combustion chamber of a jet engine is one of the hottest manufactured by man. It can run about 1400 degrees Celsius or 2552 degrees Fahrenheit.
How are nitrogen oxides produced?
it is produced form animals, plants and factory.
What does the acronym EGR represent and what does the EGR do?
Exhaust gas recirculation. The egr meters a small amount of exhaust gas back into the engine. This gas lowers the combustion temperature which lower the a mount of oxides of nitrogen in the exhaust.
