1.1 GENERAL INFORMATION
A. ENGINE INTRODUCTION
DESCRIPTION
The
“1.5L REVOTORQ”
BS VI
is a new
generation 4 Cylinder 1.5L Common-Rail
Turbocharger Intercooled Diesel Engine. This
Engine is fitted with “Delphi” common rail system
with 2000 bar injection pressure which is
controlled by a 32 bit Electronic Control Unit
(ECU).The Engine performance is optimized for
various engine speed, load and operating
conditions depending upon the various sensor’s
inputs.
Variable Geometry turbocharger Electrically
Actuated limits exhaust gas inflow to less than its
maximum capacity to prevent overload in
advance, Because this technology provides an
Engine high durability and better economic
efficiency, it still remains a market leading
product. The pressure of the exhaust gas
dramatically increases at high speeds and may
cause to the turbocharger. VGT bypasses
overloaded exhaust gas using the VGT to prevent
this potential problem.
The fuel economy and emission has been
optimized at source by means of low engine
friction, faster engine warm up, centralized
solenoid injectors, optimized combustion,
LNT+CDPF 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.
