Series turbocharger

  • Fresh air is first drawn into the low-pressure turbocharger (fixed geometry) and compressed to a higher pressure. The compressed air is then drawn into the high-pressure turbocharger (VGT), where the air is further compressed.The high-pressure air is then routed through a charge air cooler and into the engine's intake manifold.
  • By splitting the work between two turbochargers, both can operate at peak efficiency and at slower rotating speeds — lowering stress on turbocharger components and improving reliability. Series turbocharging delivers more boost pressure than single turbocharger configurations which results in higher power density, improved low-speed torque, and improved high altitude operation.

  • The HPCR fuel system provides variable common-rail pressure, multiple injections, and higher injection pressures up to 1,975 bar (29,000 psi). It also controls fuel injection timing and provides precise control for the start, duration, and end of injection.

  • EGR cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx.

  • These engines utilize a catalyzed exhaust filter that contains a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF). The DOC reacts with exhaust gases to reduce carbon monoxide, hydrocarbons, and some particulate matter (PM). The downstream DPF traps and holds the remaining PM. Trapped particles are oxidized within the DPF through a continuous cleaning process called passive regeneration.
  • Passive regeneration occurs during normal operating conditions when heat from the exhaust stream and catalysts within the exhaust filter trigger the oxidation of the trapped PM. If passive regeneration cannot be achieved due to low temperature, load, or speed, then PM is removed using active regeneration — an automatic cleaning process controlled by the exhaust temperature management system.

  • The 4-valve cylinder head provides excellent airflow resulting in greater low-speed torque and better transient response time by utilizing a U-flow design.

  • This is the most efficient method of cooling intake air to help reduce engine emissions while maintaining low-speed torque, transient response time, and peak torque. It enables an engine to meet emissions regulations with better fuel economy and the lowest installed costs.

  • Multiple rated speeds to further reduce noise and improve fuel economy; higher level of peak torque; transient response time equal to or better than Tier 3/Stage III A; low-speed torque equal to or better than Tier 3/Stage III A

  • Lower installed cost; mounting points are the same as previous engine models

  • Faster engine control unit (ECU) manages both the engine and the exhaust filter; full authority electronic controls; four times the memory, twice the RAM and double the processing speed; the input/output capability has increased 40%

  • Gear-driven auxiliary drives
  • 500-hour oil change
  • Self-adjusting poly-vee fan drive
  • Single-piece low-friction piston
  • Directed top-liner cooling
  • Low-pressure fuel system with electrical transfer pump and "auto-prime" feature
  • Optional rear PTO
