Turbo Charger

Turbo Charger:

Turbo Charger is a rotary mechanical device that produces Force induction compressed air into the IC engine\'s Combustion Chamber to get more Efficiency and power Output and Torque.

Turbine Speed 2,00,000 to 2,50,000 RPM.

Different TurboChargers & Locating in the GT POWER

Euro 1 - Fixed Geometry Turbine :

Fixed Geometry turbine is Fixed Design and Boost Pressure is determines by Exhaust flow of an Engine.

Euro 2- Wastegate Turbine:

Wastegate Turbine is Regulates the max.boost pressure we can do bypass the excess flow of compressed air and this leads to less Turbolag.

Euro 3- VGT Turbine :

VGT Turbine is Variable Geomerty Turbine generally used in Disel Engines and it is designed for Low engine speed and low accelration it gives boost pressure and also gives out put higher speed also.

Euro4- 2Stage Turbine:

This is Multistage Turbine like for Higher Perfomance Vehicles ,Heavy Duty Engines used. Twin Scroll Turbo these are used V6 and V8 Engines gernerally preferred.

Euro-5 VGC Turbine:

Variable Geometry Compression Turbine

Euro-6 e-Turbo:

This Turbine is generally Prefers in Hybrid Electric Vehicles.Power and Energy gets from Motor

2. Tutorial 6 & 7

Compressor Out Tempetrature 400k &Pressure 2.4 bar goes to an inlet and cooler through to flowsplit then finally after combustion as a exhaust gases gives kinetic Energy to Turbine inlet.The temperature rises to 800k and pressure increases 2.5 .

The Altitude can be defined like Offroad conditions ,Army Vehicles while doing Turbo Charger Modelling .

4. VGT

Varibale Geometry Turbine generally Prefers to DI engines with morethan 4 cylinders Like High perfomance cars ,Heavy Duty Trucks this Turbine is used . The Engine start point it self it gives boost pressure to intake then gives more output and effficiency. The main function is gives more Torque with in Low speed of an Engine and gives less Turbo Lag.

I noticed that some of vehicle are manufactured with VGT Turbine as given below

Volvo FM -Truck

Porshe 911 Twin Turbo VGT - Sports Car

Fiat Croma -Sedan car

Peugeot 405 - Sedan Car.

5. Understanding Diesel VGT EGR

Diesel Variable Geomerty Turbine with Exhaust Gas Recirculation .

I Understand that,

1.This Modelling part of VGT_EGR Engine The Turbine takes Kinetic Energy from the Exhaust then the Turbine rotates this is Exhaust gas recirculation.

2.Turbine energy to goes to the Compressor through shaft connected between these two and shaft is called Turbo shaft.

3. At the Compressor the ambient air through Airfilter box and Indutioned air goes to intake.

4.Before entering into the inlet Air goes to Intercooler to maintain ambient temperature.

5.EGR controller takes exhaust gas through EGR Valve Exhaust gas send it into EGR cooler .

6.Then it tansfers into thre throttler and mix the air and goes to intake throgh Ports and intake valves.

7.The Combustion action takes palce Then Exhasut the cycle repeats.

8.Through the VGT Controller Rack we can define Target boost pressure.

9.Receiver of Virtual Signal Value for VGT Controller.

10.The Exhaust goes to After Treatment process then after DOC [diesel oxidation catalytic] and DPF [diesel particulate filter] are controll the emission .

11.After this all enters into Muffler. This part designed with all boundary conditions mainly thermal and size

12.And also This component designed Control the Sound and release the Exhaust gases from the Engine.
