Why do cars produce high emissions of nitrogen oxides (NOx)?

Answer 1

THE CHEMICAL SUBSTANCE YOU REFER TO IS NOT ENTIRELY UNCOMMON IN NATURE AS WELL AS CAUSED BY COMBUSTION ENGINES. SIMPLY PUT, NOx IS A FUSED GAS BY PRODUCT CAUSED DURING THE SEPERATION AND REASSERTION OF VARIOUS MOLECULES AS THEY ARE SUPER HEATED IN THE VALVES OF A GAS FUELED ENGINE AND THEN COMPRESSED. THIS PROCESS IS ALSO FOUND IN NATURE IN INTENSE HEAT SITUATIONS SUCH AS LIGHTNING STRIKES AND FOREST FIRES. THEY ALSO CONTRIBUTE HEAVILY TO THE GLOBAL WARMING PROBLEM BY GRADUALLY BREAKING DOWN AND REDUCING TH EAMOUNT OF NATURALLY OCCURING OZONE IN THE EARTHS ATMOSPHERE.

Answer 2

I believe it is because the reaction takes place in air, which has some nitrogen. The heat causes oxidation, thus NOx.

I think cars with good catalytic converters take most of the Sox and NOx out, like the hybrids.

Answer 3

Because to put it simply Nitogen is present in air, engines breathe air, once superheated the nitogen produces NOx.

Answer 4

there could be two reasons. there are many N2 molecules in air with O2 molecules and the gas also may consists of some N atoms. the reaction N2 + O2 needs heat to occur and there is enough heat in engines
