Which outcome results when insufficient current drives a common-rail injector?

A)Reduced combustion chamber pressures occur✓

B)Pre-ignition timing advances excessively

C)Detonation sensitivity becomes significantly reduced

D)Exhaust gas recirculation increases substantially

💡 Explanation

Weak signal degrades injector solenoid activation; this mis-timing leads to inadequate atomization and reduced fuel delivery. Because the mixture burns less efficiently under low pressure, combustion completeness decreases; therefore the combustion chamber pressure decreases, rather than increasing pre-ignition or exhaust recirculation.
