1. GENERAL INFORMATION A. ENGINE INTRODUCTION DESCRIPTION The “1.5L REVOTORQ” BSVI CAFÉ (PH2) 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, Under Floor pSCR 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.
