Which risk increases when designing a turbine engine based on the Otto cycle and exceeding the stoichiometric air-fuel ratio?

💡 Explanation

Increasing air beyond the stoichiometric ratio reduces temperature, slowing oxidation. This incompleteness causes increased unburned hydrocarbon pollutant emissions primarily due to slower radical chain propagation, because less energy is available within the reaction zone, therefore pollutant formation increases, rather than decreases to cause another favorable change.
