Features

2-valve cylinder head

  • Cross flow head design that provides excellent breathing from a lower cost two-valve cylinder head

  • Fixed geometry turbochargers are precisely matched to the power level and application

  • In turbocharged engines, the air is pre-compressed. Due to the higher pressure, more air is supplied into the combustion chamber allowing a corresponding increase in fuel injection which results in greater engine output.

  • Most efficient method of cooling intake air to help reduce engine emissions while maintaining low speed torque, transient response time, and peak torque. Enables an engine to meet emissions with better fuel economy and the lowest installed costs.

  • Mounting points for Tier 3/ Stage III A engines are the same as Tier 2/Stage II engines

  • Monitors critical engine functions providing warning and/or shutdown to prevent costly engine repairs; eliminates need for add-on governing components; all lowering total installed costs. Snapshot diagnostic data that can be retrieved using commonly available diagnostic service tools
  • New common wiring interface connector for vehicles or available OEM instrumentation packages; new solid conduit and "T" connectors to reduce wiring stress, greater durability and improved appearance
  • Factory installed engine mounted ECU, wiring harness and associated components; industry standard SAE J1939 interface which communicates with other vehicle systems, eliminating redundant sensors and reducing vehicle total installed cost

  • Self-adjusting poly-vee fan drive
  • Forged-steel connecting rods
  • Replaceable wet-type cylinder liners
  • Either-side service
  • 500-hour oil change
