1.5L REVOTORQ ENGINE

1

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.
