Which risk increases most when the piezoelectric injector in a gasoline direct injection (GDI) engine experiences coil degradation?

💡 Explanation

Increased unburnt hydrocarbon emissions rise because piezoelectric injector coil degradation affects fuel atomization via reduced voltage control. Therefore, larger fuel droplets combust incompletely, rather than achieving optimal air-fuel mixture distribution under all engine loads, leading to hydrocarbon emissions.
