Question

lean air fuel mixture produce which gases less more​

Answer 1

Answer:

The greater proportion of air lowers the overall combustion temperature (there will be relatively less fuel entering the combustion chamber in the lean mixture), reducing the production of nitrogen oxides from nitrogen in air and providing the conditions for much more complete combustion of the fuel.

Explanation:

Air–fuel ratio (AFR) is the mass ratio of air to a solid, liquid, or gaseous fuel present in a combustion process. The combustion may take place in a controlled manner such as in an internal combustion engine or industrial furnace, or may result in an explosion (e.g., a dust explosion, gas or vapour explosion or in a thermobaric weapon).
