  • High power and torque already at low engine speed
  • Compact, simple installation and easy to service
  • Exhaust emission reduction system without EGR
  • Similar engine footprint for all emission standards
  • High sulfur-in-fuel tolerance
  • Wide range of optional equipment

Technical description

Engine and block

  • Optimized cast iron cylinder block with optimum distribution of forces without the block being unnecessary heavy.
  • Wet, replaceable cylinder liners
  • Piston cooling for low thermal load on pistons and reduced ring temperature
  • Tapered connecting rods to reduce risk of piston cracking
  • Crankshaft has induction hardened bearing surfaces and fillets with seven main bearings for moderate load on main and big-end bearings
  • Nitrocarburized transmission gears for heavy duty operation
  • Keystone top compression rings for long service life
  • Viscous type crankshaft vibration damper
  • Replaceable valve guides and valve seats
  • Overhead camshaft and four valves per cylinder equipped with camshaft damper to reduce noise and vibrations.

Lubrication system

  • Full flow oil cooler
  • Full flow disposable spin-on oil filters
  • The lubricating oil level can be measured during operation (Standard dipstick only)
  • Gear type lubricating oil pump, gear driven by the transmission

Fuel system

  • Self de-aerating system. When replacing filters all fuel stays in the engine.
  • Non-return fuel valve
