emissions regulations, and the effective dates of each regulation Tier/Stage.
• Describe CAT solutions for TIER 4 Interim/Final NOx, Hydrocarbon and PM
reduction.
• Summarize the need for, and strategy of, Diesel Particulate Filter (DPF)
regeneration and NOx Aftertreatment reduction.

PPE Required

Participants must provide their own safety glasses, steel-toed footwear, gloves, hard hat, hearing protection, and coveralls with Hi-Visibility Markings.

PREREQUISITES

None.

  • Locate and identify all the components related to Tier IV Interim and Final on a variety of Caterpillar engines.
  • Describe the function and purpose of each component on the Tier IV Interim and Final engines.
  • Trace the exhaust flow in the NOx Reduction System (NRS).
  • Identify different fuel systems use on Tier IV Caterpillar engines.
  • Trace fuel flows on each fuel system for Tier IV engines.
  • Identify and explain the function of the lights and switches as they relate to Tier IV Interim and Final.
  • Describe the warning methodology as the soot load increases from 0% to 140%.
  • Identify the different regeneration types and at what soot level they become available.
  • Explain why Diesel Exhaust Fluid (DEF) was chosen.
  • Trace the exhaust gas in the Selective Catalytic Reduction (SCR) system.
  • Describe the process for preventing NH3 slip, and NOx slip with in SCR system.
  • Summarize the safety concerns associated with SCR system.
  • Set up and record DATA Logs pertinent to T4 using Cat ET
  • Develop graph sets based on recorded DATA Logs and interpret graph.
  • Troubleshoot the CAN BUS network attached to the T4 engine NOX, HC and PM reduction systems.
