TDI (TURBOCHARGED DIRECT IGNITION)
INTRODUCTION
TDI
Turbocharged direct injection is innovative engine design that delivers a combination of
1.Performance.
2.Fuel economy .
3. Low emission.

TURBOCHARGER
The function of turbocharger is to increase the amount of air entering the engine
The power and the torque increases tremendously compared to an engine without a turbocharger
WORKING
TDI engines use a computer-controlled injection system
Fuel is directly sprayed into the combustion chamber at very high pressure
This helps in promoting complete combustion
