← TechnologyWhich outcome occurs when electronically controlled diesel fuel injectors experience electromagnetic interference?
A)Increased exhaust opacity due to misfiring✓
B)Elevated coolant temperature from afterburning
C)Reduced engine torque caused by leaning
D)Premature turbocharger failure from overboost
💡 Explanation
When EMI affects injector control, unintended fuel pulses occur because solenoid actuation becomes erratic, leading to incomplete combustion. Increased exhaust opacity results, rather than overheating, torque loss, or premature turbocharger degradation which stem from different root causes relating to cooling, overall fueling, or turbine speed.
