← TechnologyWhich consequence results when a fuel injector in a gasoline engine experiences electrical failure?
A)Lean combustion fuel mixture✓
B)Rich combustion air mixture
C)Stoichiometric operation continuation
D)Oxidation catalyst overheating onset
💡 Explanation
Electrical failure in the fuel injector halts fuel delivery due to solenoid deactivation causing fuel starvation referred to as lean combustion, because the air-fuel ratio greatly increases. Therefore, a lean mixture develops, rather than rich or stoichiometric operation, potentially creating misfires and engine damage.
