How A TurboCharger Works

What Is A Turbocharger?

A turbocharger is a kind of air pump taking air at ambient pressures (atmospheric pressure),compressing to a higher pressure and passing the compressed air into the engine via the inlet valves—generating pressure or “boost”—allowing more fuel to be used, and thus helping the engine produce more power.

How Does A Turbocharger Work?
The waste exhaust gases of the engine are utilised to drive a turbine wheel, which is connected to a compressor wheel by a shaft. The compressor or air wheel sucks in air through the air filters and passes this into the engine. As the waste gases are expelled from the engine, they are directed to the turbine or hot wheel of the turbo and so completes the cycle.

1. Capture
Instead of escaping through the exhaust pipe, hot gases produced during combustion flow to the turbocharger.The cylinders inside an internal combustion engine fire in sequence (not all at once), so exhaust exits the combustion chamber in irregular pulses. Conventional single-scroll turbochargers route those irregular pulses of exhaust into the turbine in a way that causes them to collide and interfere with one another, reducing the strength of the flow.In contrast, a twin-scroll turbocharger gathers exhaust from pairs of cylinders in alternating sequence.

2. Spin
The exhaust strikes the turbine blades, spinning them at up to 150,000 rpm.The alternating pulses of exhaust help eliminate turbo lag.

3. Vent
Having served their purpose, exhaust gases flow through an outlet to the catalytic converter, where they are scrubbed of
carbon monoxide, nitrous oxides and other pollutants before exiting through the tailpipe.

4. Compress 
Meanwhile, the turbine powers an air compressor, which gathers cold, clean air from a vent and compresses it to 30 percent above atmospheric pressure, or nearly 19 pounds per square inch.
Dense, oxygen-rich air flows to the combustion chamber.The additional oxygen makes it possible for the engine to burn gasoline more completely, generating more performance from a smaller engine.As a result, the TwinPower engine generates 30 percent more power than a non-turbocharged one of the same size.
