Here's a breakdown:
How it Works:
* Superchargers are mechanically driven by the engine's crankshaft, using a belt or gear system. They are usually used on smaller engines and produce power at lower RPMs.
* Turbochargers are driven by exhaust gases, using a turbine. They are more efficient and can produce higher power at higher RPMs, making them popular on larger engines.
Benefits:
* Increased Power: More air in the cylinders means more fuel can be burned, resulting in higher horsepower and torque.
* Improved Acceleration: The extra power helps the engine accelerate quicker.
* Better Fuel Efficiency: While not always the case, some engine blowers can improve fuel efficiency at certain speeds and loads.
Drawbacks:
* Increased Complexity: Blowers add complexity to the engine, which can increase maintenance costs.
* Higher Stress on Engine: Blowers can put extra stress on engine components, which can shorten their lifespan.
* Reduced Fuel Economy: While some blowers improve fuel economy, others can actually decrease it, especially at lower speeds.
Types of Engine Blowers:
* Roots-type: These are common in superchargers and have large rotors that compress air.
* Screw-type: Similar to roots-type, but use screws to compress air.
* Centrifugal: These are common in turbochargers and use a spinning impeller to force air into the engine.
In Summary:
An engine blower is a device that increases an engine's power and torque by forcing more air into the cylinders. They come in different types, each with their own pros and cons. While they offer performance benefits, they also add complexity and can potentially impact engine longevity and fuel economy.
