MEMORANDUM

SUBJECT: Test Procedure Review with Cummins, Volvo, Navistar, Paccar,
Daimler Eaton and Allison

FROM: James Sanchez

TO:  Greenhouse Gas Emissions Standards and Fuel Efficiency Standards
for Medium- and

Heavy-Duty Engines and Vehicles - Phase 2 - Docket EPA-HQ-OAR-2014-0827

This memo documents communication on February 11, 2016 between
representatives of Cummins, Volvo, Navistar, Paccar, Eaton, Allison,
Daimler, Caterpillar, Hino, EMA and EPA to discuss heavy-duty test
procedures proposed in the Phase 2 greenhouse gas and fuel efficiency
standards for heavy-duty vehicles notice of proposed rulemaking.

Participants: 

Allison – 

Caterpillar – George Lin

Cummins – Jackie Yeager, Manik Narula

Daimler – Gerald Freitag, David Kayes, Inderpal Singh

Eaton – Erik Dykes

EMA – Tim Blubaugh

EPA – Houshun Zhang, James Sanchez

Hino – Mark Siddall

Navistar – Dave Gardner, Cortney Guzlas, Nathan Beauchamp, Laura
Ricart, Matt Hunkler

PACCAR – Mark Malowicki, Costi Nedelcu, Erin Luke, Dan Kieffer

Volvo – Marc Miller, Tony Greszler, Tim Connors

Discussion and follow-up items (with owner's name in bold): 

SwRI testing – Houshun

No new data to share yet, some progress being made on gasoline engine
testing

Road grade evaluation – Mark M., James

Mark M. of PACCAR shared an analysis of Profile D (slides emailed
previously).  Profile D matches truck data reasonably well for
cumulative percent grade and half hill length but differs on rate of
change of grade.

James shared a similar type of analysis

Matt H. reported seeing some impact on “binary” engine operation due
to GEM driver model which does not allow the vehicle to overspeed going
downhill.  Also he is investigating changes to the cycle.

Manufacturers are continuing to evaluate Profile D

SEA process – All 

Questions on how to run SEA for cycle average map for child rating and
for powertrain test

Topics for future calls: 

(TBD) SwRI results (N13 365, gasoline engine) – Houshun

(TBD) Impact of mass in road grade analysis – Volvo
