Which inefficiency results when insufficient fuel vaporization occurs due to low nozzle atomization during direct injection in a modern gasoline engine?

💡 Explanation

Increased unburnt hydrocarbon emissions arise because inadequate vaporization hinders complete combustion via the Leidenfrost effect limiting the surface area of fuel available for reaction; therefore, unburnt fuel is released rather than fully oxidizing, leading to lower combustion efficiency.
