Study Notes
Turbocharged System Components
- The intercooler cools the air at constant pressure, increasing its density before supplying it for compression in the engine cylinders.
Gas Turbine Function
- The gas turbine is driven by the exhaust gases in the turbocharged system.
Energy Source for Gas Turbine
- The energy source for the gas turbine is the exhaust gases in the turbocharged system.
Scavenge Ports Purpose
- The scavenge ports in the turbocharged system are used to scavenging the exhaust gases and supply them to the turbine.
Exhaust Gas Energy Effect
- At any engine speed, the exhaust gas energy must cause the turbine to spin at a speed sufficient to drive the compressor, providing the boost pressure required by the engine.
Test your knowledge on turbocharge systems and how they work to increase the power output and efficiency of modern engines. Learn about charge air coolers and how they enhance the system's efficiency by cooling the air before compression in the engine cylinders.
