AIGF Exit Exam • Set 6 Question 14 of 30

Upgrading _______ to VTA technology will increase efficiency

✓

Direct Answer

Option D: Turbo charger

Variable Turbine Area (VTA) technology allows for dynamic adjustment of the turbine nozzle ring geometry. This optimizes the turbocharger's performance across varying engine loads, ensuring superior scavenging and air delivery compared to fixed-geometry units, thereby directly enhancing the overall thermal efficiency of the main propulsion plant.

All Options

exhaust boiler

None of the above

propulsion shaft

Turbo charger (Correct Answer)

Detailed Explanation & Context

Relevant Framework: STCW 2010 Manila Amendments • DG Shipping E-Learning & Exit Exam Standards • Advanced Training for Ships subject to the IGF Code (AIGF).
