Tier 4A Engine Technology: An Overview

Each month, I’ll introduce a Case IH expert to be our Be Ready guest blogger. I’ve invited Leo Bose as our first expert blogger, to discuss Tier 4A engine technology, facts or fiction. Leo is the training manager for Case IH and is responsible for developing the North American training strategy. He has been with Case IH for more than 16 years, serving in various positions, including combine marketing manager, training specialist on harvesting and planting equipment, training specialist on tractors and product support specialist on under-100 horsepower tractors. He also hails from a farm background!

Be sure to ask questions and we’ll help get the information you need to make informed decisions about Tier 4A.

School of Hard NOx: SCR Primer

By now, you’ve probably heard about the new federal regulations mandating cleaner, more efficient engines beginning in 2011. Maybe you’ve even heard some acronyms like SCR and CEGR and wondered what it means to you.

Listen up, class is in session!

Tier 4 emissions regulation was created to crack down on air pollutants – primarily particulate matter, which we know as soot, or unburned fuel, and nitrogen oxides (NOx) emitted as a by-product of an engine’s internal combustion process. Doing this requires the addition of an exhaust after-treatment system, such as Cooled Exhaust Gas Regeneration (CEGR) or Selective Catalytic Reduction (SCR).  (more…)
