Types of Turbo

                 Types of  Turbo (PART-1)

1) Types of turbo

(1) Single turbo 

(2) TwinTurbo

(3) Twin scroll turbo 

(4)Variable twin scroll turbo 

(5)Twin scroll 

(6)Variable- geometry turbocharger 

1] Single Turbo  {working}

A single turbocharger is mounted to the exhaust manifold and uses exhaust gases to spin the turbine. This turbine is connected to a compressor, which compresses air and sends it into the engine. 

*Advantages*

1) It is less expensive than twin-turbo system

2)The weight of your engine is reduced.(It gives small engines more power)

3)It add 70 to 150 HP to engine .

*Disadvantage*

1)The single turbo has a somewhat narrow effective RPM range.

2)It produce a lot of heat { This can melt the components of engine and may

 turbocharger fail}

*Uses*

They are used in muscular car ,sports car ,racing car, Racing bike , sports bike etc.

2] TwinTurbo {working}

A twin-turbocharger works by using two turbochargers of the different size (for eg-66mm compressor and 68mm turbine wheels )to force air into the engine's cylinders to add extra horsepower. 

*Advantages*

1) increase air and fuel intake nearly twice as much as the same engine would without a turbocharger.

2)lt has the potential for reductions in turbo lag compared to one single turbocharger doing all the work.

*Disadvantage*

1)They are inherently more complicated and more expensive.

2)Due to the increased number of parts and potential failure points - particularly when the systems are older.

*Uses*

They are used in BMW, LANCIA, and SAAB cars.

 

3] Twin scroll turbo {working}

 A twin-scroll turbocharger gathers exhaust from pairs of cylinders in alternating sequence. The exhaust strikes the turbine blades, spinning them at up to 150,000 rpm. The alternating pulses of exhaust help eliminate turbo lag.

*Advantages*

1)Twin-scroll turbochargers  increase low-end torque, improve boost response, raise power throughout the powerband, maximize turbine efficiency, reduce engine pumping losses, improve fuel economy, decrease intake charge dilution during valve overlap and lower exhaust gas temperatures.

*Disadvantage*

1)poor efficiency at high engine load and speed. 

2)complex and expensive exhaust manifold and turbine casing.

*Uses*

In the BMW X5 M and X6 M, twin-scroll turbos are used, one on each side of the V8. For parallel twin turbos on 'V' shaped engines, the benefits (and drawbacks) are very similar to single turbo setups.
