Two stage turbo charging of auxiliary engines increases
Direct Answer
Option D: reduce emissions
Two-stage turbocharging optimizes scavenging and combustion efficiency in auxiliary engines, particularly when burning low-flashpoint fuels. By increasing charge air density and pressure, the system ensures more complete combustion, which significantly reduces particulate matter and nitrogen oxide emissions, aligning with MARPOL Annex VI requirements for cleaner maritime operations and improved engine performance.
