INTRODUCTION:

The 2.2 L DICOR engine used on this vehicle is a

state of art modern Direct Injection Common Rail

diesel unit. This engine is using twin over head cam

shafts and 16 valves which help in good breathing.

Delphi second generation common rail diesel

injection system with 1600 bar injection pressure

is used and controlled by a fast 32 bit electronic

control unit. The engine performance is optimized

for various engine speed, load and operating

conditions depending upon the various sensors

input.

The turbocharger (VNT) used on this engine works

on Variable Turbine Technology (VTT) having low

inertia of turbine and compressor wheels which

reduce the turbo lag at low engine speeds and

improves the transient response of the vehicle. This

turbocharger incorporates many movable vanes in

the turbine housing to control the exhaust flow

against the turbine blades which enables higher

power, torque, lower fuel consumption and

emissions of the engine.

The fuel economy and emission has been optimized

at source by means of low engine friction, faster

engine warm up, centralized injectors, optimized

combustion, closed coupled catalytic converter,

closed loop operation of the turbocharger (VNT)

etc. Hydraulic Lash Adjusters and Roller Finger

Followers are used for maintenance free quiet

operation and reduced friction. Toothed belt drive

with automatic belt tensioner is used for quiet

engine operation for longer period.

The engine NVH is optimized by means of power

train stiffeners and stiffened engine components,

optimized engine mounts, multiple injection

strategy etc. The engine weight has been

optimized by using Aluminum cylinder head,

gallery cooled piston, non linered cylinder block

with spherical skirt, superior alloy material for high

strength.
