Host: Tom Briggs
Duration: 59:19
Summary
Join Southwest Research Institute (SwRI) for a live introduction to the Technology Initiative for Emissions Reduction (TIER-5) Consortium — a precompetitive consortium formed to de-risk technology pathways for off-road diesel engines ahead of the California Air Resources Board’s (CARB’s) proposed Tier 5 emissions standards.
The webinar covers the Tier 5 challenge for 19- to 56-kilowatt (kW) engines, SwRI’s three-phase development plan and what founding membership includes.
Topics Covered
-
The Tier 5 challenge: Regulatory timeline, emissions targets, and why 19–56 kW is uniquely hard to solve.
-
Three-phase development plan: Baselining, technology-lever prioritization, and trade-off analysis & recommendations.
-
Membership & deliverables: Full IP rights, test-cell data, calibrated models, and topic voting rights.
-
Founding member Q&A: Open discussion on scope, timeline, and how to get involved.
