1. GENERAL INFORMATION
A. ENGINE INTRODUCTION
DESCRIPTION
The
“2.0L KRYOTEC”
is a new generation 4
Cylinder 2.0L Direct injection Common-Rail
Turbocharger Intercooled Diesel Engine. This
Engine is fitted with common rail system with
higher injection pressure (1600 bar) which is
controlled by a Electronic Control Unit (ECU).The
Engine performance is optimized for various
engine speed, load and operating conditions
depending upon the various sensor’s inputs.
The turbocharger used on this engine is
electronically actuated 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, fully electronic
controlled fuel injection system, EGR (exhaust
gas recirculation) and Diesel particulate filter with
oxidation catalyst.
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 aluminum alloy pan. The engine
weight has been optimized by using Aluminum
cylinder head, gallery cooled piston.
