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 April 7, 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 – Scott Mundy

Caterpillar – 

Cummins – Manik Narula, Jackie Yeager

Daimler – Gerald Freitag, Don Keski, Inderpal Singh

Eaton –

EMA – Tim Blubaugh

EPA – Houshun Zhang, James Sanchez, Matt Spears

Hino – Tom Manley

Navistar – Dave Gardner

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

Volvo – Marc Miller, Tim Connors, Tony Greszler, Chuck Kaslavage,
Steve Berry

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

ISL engine test results – Manik 

Cummins presented cycle average map test results for ISL 450 and 300 hp
ratings – see slides emailed previously

Cycle average map performance matches that of steady state map on cruise
cycles

Addressing N/V overlap – Manik 

Cummins presented example of how to revise generic vehicle definition to
prevent N/V overlap – see slides emailed previously

EPA asked companies to consider options of 1) adding generic vehicle
configurations, or 2) selecting custom vehicle configurations instead of
generic

Discussion about how to certify vehicles not designed to reach 65 or 55
mph 

Road grade profiles – EPA

Discussion about a couple options for further modifying the cycles to
better match time at peak torque in-use:

Add miles at zero grade, or

Reduce grade by a fixed percentage (same effect as reducing vehicle
mass)

Topics for future calls: 

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

(4/21) Road grade evaluation – TBD
