6135 PowerTech PSX Tier 4Interim Tier 4 PowerTech™ PSX 6135 Industrial Engine
PowerTech PSX 13.5L engines feature series turbochargers that deliver more boost pressure than single turbocharging configurations which results in higher power density, improved low-speed torque, and improved high altitude operation.

These high-performing engines use cooled exhaust gas recirculation (EGR). This technology cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx. These engines also 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.

Tier 3 PowerTech™ Plus 6135 Industrial Engine
This 13.5L, 6-cylinder engine, meets emissions requirements without sacrificing performance. New features include cooled exhaust gas recirculation, variable geometry turbocharger, 4-valve cylinder heads, and an electronic unit injector fuel system. Power ratings, fuel economy, torque levels, transient response time, and other features meet or exceed Tier 2/Stage II.

Features 6135 PowerTech Plus Tier3
Engine performance - PSX-Interim Tier 4 & Plus-Tier 3
  • Multiple rated speeds to further reduce noise and improve fuel economy
  • Higher level of peak torque
  • Optional power bulge
Cooled EGR - Exhaust Gas Recirculation - PSX-Interim Tier 4 & Plus-Tier 3
  • EGR cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx.
Series Turbocharger - PSX-Interim Tier 4
  • 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 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.
Variable Geometry Turbocharger (VGT) - Plus-Tier 3
  • Varies exhaust pressure based on load and speed to insure proper EGR flow; greater low-speed torque, quicker transient response, higher peak torque, and best-in-class fuel economy.
Electronic unit injector (EUI) and engine control unit (ECU) - PSX-Interim Tier 4 & Plus-Tier 3
  • The EUI fuel system provides higher injection pressures up to 2,275 bar (33,000 psi) for Tier 4 engines, and up to 2000 bar (29,000 psi) for Tier 3. One ECU controls the exhaust filter, as well as fuel system and provides precise control for the start, duration, and end of injection.
4 - valve cylinder head - PSX-Interim Tier 4 & Plus-Tier 3
  • The 4-valve cylinder head provides excellent airfow resulting in greater low-speed torque and better transient response time by utilizing a cross-flow design.
Air-to-air aftercooled - PSX-Interim Tier 4 & Plus-Tier 3
  • 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.
Exhaust Filters - PSX-Interim Tier 4
  • 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.
Compact size - PSX-Interim Tier 4 & Plus-Tier 3
  • Horsepower/displacement ratio is best-in-class
  • Lower installed cost
  • Mounting points are the same as previous engine models
Additional Features - PSX-Interim Tier 4
  • JDLinkTM lets you monitor, protect, and maintain your equipment 24/7
  • Premium software option integrates with equipment or vehicles to reduce engineering and installation costs
  • 500-hour oil change
  • Optional factory installed variable-speed fan drive improves fuel economy and reduces noise levels
  • R.H. and L.H. engine-mounted final fuel filters
  • Low-pressure fuel system with electrical transfer pump and "auto-prime" feature
Additional Features - Plus-Tier 3
  • Gear-driven auxiliary drives
  • 500-hour oil change
  • self-adjusting poly-vee fan drive
  • R.H. and L.H. engine-mounted fuel filters
  • single-piece low friction piston
  • optional rear PTO
  • low-pressure fuel system with "auto-prime" feature
  • directed top-liner cooling
