For an optimized diesel engine operating at high altitude conditions with reduced air density, which feedback mechanism manages fuel injection duration?

💡 Explanation

Reduced air density requires a shortened fuel injection duration, because the Mass Air Flow (MAF) Correction uses a feedback loop to adjust injector pulse width to maintain optimal air-fuel ratio. Therefore, less fuel enters the cylinder, rather than the engine running excessively rich.
