Turbo charger refitting _______ efficieny and reduce emissions of main engine
Direct Answer
Option D: increases
Refitting modern turbochargers optimizes scavenging and combustion efficiency. By improving the air-fuel ratio and increasing charge air pressure, the engine achieves more complete combustion, which significantly reduces particulate matter and NOx emissions, aligning with the energy efficiency requirements mandated by MARPOL Annex VI and IGF Code operational standards.
