Marine Turbocharger
"A forced induction device that drives a compressor using the energy from the engine's exhaust gases, significantly increasing engine power and efficiency."
Definition
A Marine Turbocharger is a turbine-driven forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra compressed air into the combustion chamber.
How It Works
- Turbine Side: Hot exhaust gases from the engine spin a turbine wheel at very high speeds (up to 20,000+ RPM).
- Compressor Side: The turbine is connected via a shaft to a compressor wheel, which draws in fresh air and compresses it.
- Intercooler: The compressed air (which is hot) passes through a cooler to increase its density before entering the engine cylinders.
Importance
Without a turbocharger, a modern marine diesel engine would produce significantly less power and consume far more fuel. It is the heart of the engine's "breathing" system.
