TIER 4 Final Emissions Solutions Outlined in Rexroth Brochure

TIER 4 Final Emissions Solutions Outlined in Rexroth Brochure

In 2014, Tier 4 Final Regulations will be in effect, and diesel systems will be required to operate generating emissions to be at 10 percent of Tier 3 levels for particulate matter (soot) and 50 percent of nitrous oxide (NOx) levels.


This significant reduction will force many mobile equipment manufacturers to fully redesign their systems, which can impact the function and performance of equipment such as backhoes, excavators, telehandlers and other systems.


The new brochure details Rexroth’s insights into the engineering challenges facing mobile equipment builders as they engineer TIER 4 compliant machines including:

  • Expanded space requirements -- exhaust cooling systems that may require up to 15 to 40 percent more space
  • Increased cooling systems -- to maintain a narrower engine temperature range to control emissions
  • Changed dynamic response of diesel engines -- if machine developers downsize the engine to control emissions, that could impact machine performance
  • Increased operating and equipment costs -- If a piecemail approach is taken to redesign systems, component costs can escalate and operational performance suffers


The brochure also provides detailed concepts from Rexroth on ways to address these issues through optimized hydraulics and drives solutions, with specific recommendations about how to apply cutting edge mobile technologies such as hydrostatic fan drives, diesel hydraulic controls and variable speed pumps to create TIER 4 compliant mobile machines that are cost-effective and competitive solutions.
