← TechnologyWhich consequence results when ultrasonic fuel injection deposits form in gasoline direct injection (GDI) engine injectors?
A)Lean air-fuel mixture develops✓
B)Injector overheats and seizes
C)Combustion knock reduces engine life
D)Fuel pump efficiency increases
💡 Explanation
A lean air-fuel mixture results, because deposit formation obstructs the 'Atomization' mechanism, causing larger droplets and reduced surface area for vaporization. Therefore a lean mixture develops, rather than rich, because less fuel is delivered than programmed due to restricted injector flow.
