Which outcome is amplified during stoichiometric fuel injections in modern gasoline engines?

💡 Explanation

Catalytic converter thermal runaway is amplified through over-temperature excursions due to incomplete combustion by `exhaust stoichiometry`, because excess hydrocarbons reach the catalyst and oxidize rapidly, therefore significantly raising temperature, rather than under normal carefully measured conditions.
