Small Tips
Professional Knowledge of Turbocharger
Core Concept & Principle
Turbo is a device that increases the power and torque output of an engine by forcing extra compressed air into the combustion chamber. It is typically driven directly by the engine's crankshaft via a belt, gear, or chain.
The power output of an engine is fundamentally limited by the amount of fuel and air it can ingest. By compressing the intake air, more oxygen molecules are packed into the same cylinder volume, allowing for more fuel to be injected and burned, resulting in a more powerful explosion and increased power.
01
Turbo has how many type ?
a. Roots turbocharger
B.Twin-Screw turbocharger
C.Centrifugal Turbocharger
02
Key Components & Parameters
A. Bypass Valve (Blow-off Valve)
B.Intercooler
C.Spool-up Time / Response Time
03
Advantages & Disadvantages
A. Advantage
No Lag: Direct engine drive provides instantaneous throttle response and immediate power delivery.
Linear Power Delivery: Power increase is more linear with engine RPM.
Relatively Simple Installation: No connection to the exhaust system simplifies plumbing.
High-RPM Performance: Capable of sustaining extremely high RPM and boost levels in certain applications (e.g., drag racing).
B:Disadvantage :
Parasitic Loss: Draws power directly from the engine's crankshaft to operate, which is known as parasitic loss.
Reduced Engine Efficiency: Parasitic loss often leads to lower fuel economy compared to turbocharged engines.
Increased Engine Load: Puts additional strain on engine components like the crankshaft and bearings.
Noise and Heat: Typically generates additional noise and adds more heat to the engine bay
