### System Description: Turbo-charging a Two-Stroke Cycle Main Engine
A turbocharger on a two-stroke marine diesel engine is a critical component for achieving high power output and thermal efficiency. It utilizes the energy from the engine's exhaust gas, which would otherwise be wasted, to supply a dense charge of fresh air for combustion. This process is known as turbocharging, and the air supply method is called scavenging.
#### 1. Principle of Operation
The system operates on a self-sustaining energy recovery loop:
