Coming Soon

Course Length

TBD

COURSE DESCRIPTION

Course Length: 2 x 10-hour days
Target Audience: Service Technicians

This course is designed to enable the participants to properly troubleshoot, diagnose, and determine the root cause(s) of failures in the Cat TIER 4 emissions systems. Review of system operations for TIER 4 Interim/Final Emissions. Identify the key exhaust emissions being regulated, the timeline for non-road 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 After treatment 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.

COURSE OBJECTIVES

After completion of the course the participant will be able to:

  • Identify the emissions being reduced in Tier IV Interim and Final.
  • Describe Caterpillar’s solutions to reduce emissions for Tier IV Interim and Final.
  • 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.
  • Troubleshoot, diagnose, and determine the root cause(s) of failures of CAT Tier 4 emissions systems.
  • Use ET, SIS, Schematics, and material provided to accomplish the troubleshooting.
