What is a supercharger?
A supercharger is an air compressor used for forced induction of an internal combustion engine. The greater mass flow-rate provides more oxygen to support combustion than would be available in a naturally-aspirated engine, which allows more fuel to be provided and more work to be done per cycle, increasing the power output of the engine. The main difference between a turbocharger and a supercharger is that turbochargers are powered by the engine’s exhaust gas, while the superchargers are powered mechanically by a belt, gear, shaft, or chain connected to the engine’s crankshaft.
A supercharger is any piece of equipment that compresses the air being delivered to an engine, allowing the combustion chamber to be overfilled without enlarging the space. The higher concentration of oxygen provided by a supercharger is matched with a larger amount of fuel from the fuel injectors. By this definition, a turbocharger is actually of the supercharger family, although it is often thought of as a completely different kind of device. A supercharger comes in two different variations: positive displacement, and dynamic. A positive displacement supercharger pushes air into the engine at a constant speed, while a dynamic supercharger uses velocity to manipulate the pressure in the air. In either case, oxygen is compressed as it is delivered to the engine, allowing more power to be gained from every explosion in the combustion chambers. In contrast, cars that do not have a supercharger draw air in using its natural flow, monitoring and regulating the amount via sensors and valves
A Supercharger is a device used to increase the “effective displacement” and volumetric efficiency of an engine, and is often referred to as a blower. A supercharger is powered mechanically by belt- or chain-drive from the engine’s crankshaft. Bolted directly to the intake manifold (roots type) or on the side of the engine (centrifugal), the supercharger drive pulley is attached to the internal impeller (compressor wheel) by a shaft. The drive pulley is attached to the engines crank pulley via a belt. As you increase the rpm’s of the motor, the supercharger’s internal impeller (compressor wheel) spins faster. This allows the supercharger to compress air inside of its casting before it forces it into the engine. The speed at which the impeller spins, determines how much boost can be produced. Changing the drive pulley is a simple way to increase or decrease your boost. Safety & Efficiency A turbocharger & supercharge can increase you vehicles safety via increased power. This increased p
To understand what a supercharger is, you must think of a motor as a large air pump. On a 4-stroke engine you have an intake stroke that occurs when the piston moves (typically) in a downward position allowing a charge (gas/air mix) to enter the combustion chamber. This is followed by the compression stroke in which the piston moves upwards compressing the charge. At this point the spark plug receives an electrical current from the ignition system allowing the fuel to burn (not explode) creating the pressure which moves the piston downward there by creating energy, Finally as the piston reaches the bottom of its stroke the exhaust valves open and the piston travels upward again to force out the spent fuel and gas. At redline this entire process happens about 100 times per second. The efficiency with which an engine can receive, burn, and exhaust these gases is measured as volumetric efficiency.
