What Are Turbochargers?
Turbochargers are forced induction devices that compress the air flowing into an engine’s combustion chamber. By squeezing more air into each cylinder, they allow more fuel to be added. The result? Increased power from each explosion. A turbocharged engine produces more overall power than a non-turbocharged engine of the same size. This improved power-to-weight ratio means smaller engines can achieve higher horsepower more efficiently, translating to fewer trips to the gas station.
How Do They Work?
Exhaust-Driven Energy: Turbochargers utilize exhaust gases from the engine to spin a turbine. This turbine, connected to a compressor, forces additional air into the engine.
High-Speed Rotation: The turbine spins at speeds between 80,000 and 200,000 rotations per minute (rpm), significantly faster than most car engines.
Temperature Challenges: Since the turbine is linked to the exhaust, it operates at very high temperatures.
Boosting Horsepower
The typical boost provided by a turbocharger is 6 to 8 pounds per square inch (psi). Considering that normal atmospheric pressure is 14.7 psi at sea level, this means you’re getting about 50% more air into the engine. While it doesn’t always translate directly to 50% more power due to efficiency considerations, a turbocharged engine still delivers substantial improvements.
In summary, turbochargers revolutionize engine performance by maximizing air intake, enhancing combustion, and ultimately boosting horsepower. Whether on the racetrack or the highway, turbos play a vital role in modern automotive engineering.
