Fresh air anti-lag is a system designed to improve turbocharger response in internal combustion engines, particularly in high-performance applications. It achieves this by introducing fresh air into the exhaust manifold, which helps to spin the turbine faster.
How Fresh Air Anti-Lag Works
Fresh air anti-lag systems typically work by:
- Introducing fresh air into the exhaust manifold: This is done by diverting a portion of the intake air into the exhaust system, either directly or through a separate pipe.
- Increasing exhaust gas velocity: The additional air increases the volume and velocity of the exhaust gases, which spin the turbine faster.
- Reducing turbo lag: This faster spinning turbine helps to spool up the turbocharger more quickly, resulting in a faster response from the engine.
Benefits of Fresh Air Anti-Lag
- Improved throttle response: Faster turbocharger response leads to a more immediate power delivery.
- Increased horsepower and torque: The increased airflow through the engine can lead to higher horsepower and torque outputs.
- Enhanced performance: Fresh air anti-lag can significantly improve the overall performance of a turbocharged engine.
Examples of Fresh Air Anti-Lag Systems
Fresh air anti-lag systems are commonly found in:
- Drag racing cars: Drag racers need maximum power and acceleration off the line, and fresh air anti-lag helps to achieve that.
- Rally cars: Rally cars often experience sudden changes in throttle position, and fresh air anti-lag helps to ensure that the turbocharger is always spooled up.
- Other high-performance applications: Any application where quick turbocharger response is critical can benefit from fresh air anti-lag.
Conclusion
Fresh air anti-lag is a sophisticated system that can significantly improve the performance of turbocharged engines. It achieves this by introducing fresh air into the exhaust manifold, which helps to spin the turbine faster and reduce turbo lag.
