BEARINGS
Replaceble, precision type steel backed shells with higher load bearing capacity
Superior resistance to corrosion and wear due to copper-lead formulation. Lead-tin overlay
for fast and effective break-in surface.
-> CAM SHAFT
Induction hardened, alloy steel, broad lobe cam shafts precisely control valve and injector
lobes. Replaceable precision type cam bushes Hardened, roller type cam shaft followers
longer cam and follower life.
-> CONNECTING RODS
I beam section, drop forged, alloy steel connecting rod with easy in-frame engine overall
capability. Rifle drilled pressure lubrication of pistion pins.
-> COOLING SYSTEM
Belt driven centrifugal water pump. Large volume coolant passages provide even flow of
coolant around cylinder liners, valves and injectors . System desiged for Indian ambient
temperature. Corrosion inhibitor coolant is environment friendly, checks foaming, scaling,
rust ,corrosion . controls pH value and neutralises acids.
-> COUNTER BALANCER
Crankshaft driven, Located in Oil pan.
-> CRANK SHAFT
High tensile strength, vacuum degassed medium carbon alloy steel forging . Induction
hardened pins and journals for high fatigue resistance, Toughened core provides better
compressive fatigue strength.. Dynamically balance in all planes.
-> CYLINDER BLOCK
Alloy cast iron with removable wet liners. Cross bolt support to main bearing cap provides
extra strength and stability.
-> CYLINDER HEADS
Alloy cast iorn, stress relieved , Each head serves two cylinders.. Designed for maximum
coolant flow across the cylinder and for optimum swirl for better combustion /fuel efficiency
and emissions. Valve seat inserts are corrosion resistant.
-> GEAR TRAIN
All gears are hardened helical gears driven from crank shaft and located at front the block.
-> CYLINDER LINERS
Replaceable wet liners dissipate heat faster than dry liners and easily replaced without
reboring the block.
-> FUEL SYSTEM
MICO / BOSH self adjusting direct injection. Mechanical governor for droop governing
characteristics. This system has high pressure in fuel lines and high injection pressure in
the cylinder for efficient fuel combustion and lesser fuel leakages.
-> LUBRICATION
Efficient, forced lubricating oil system using gear pump with internally drilled passages in
cylinder block and heads to feed all bearings and other parts including piston cooling . Oil
cooler, full flow filters and by-pass filters maintain oil quality, thus maximising oil and
engine life.
-> PISTONS AND PISTON PINS
Aluminium alloy with Ni-resist ring carrier piston to minimise piston ring leakages.Cam
tuned barrel shaped to compensate for thermal expansion. Piston pin ism fullfloating , solid
steel retained by snap rings.
-> TURBOCHARGERS WITH AFTER COOLER
Holset turbocharger with after cooler mounted on the engine converts energy of exhaust
gases for more power , improved fuel economy, altitude compensation and lower exhaust
temperature , smoke and noise levels.
-> VALVES
Chrome plated type intake and exhaust valves. Wear resistant face on exhaust valve.
-> STANDARD EQUIPMENT
