Which outcome occurs when excessive charge cooling condensation introduces liquid fuel droplets into an Otto cycle's combustion chamber post fuel injection?

💡 Explanation

Unburnt hydrocarbon emissions increase because liquid fuel prevents complete oxidation; therefore significantly more fuel remains uncombusted, rather than forming CO₂ and H₂O, because non-vaporised droplets will not react due to reduced reaction area and local non-stoichiometry.
