1. Introduction/Background
The Taiwanese Government is in the process of adopting US
mobile source emission regulations. As part of their program, they
have been developing the appropriate heavy-duty engine emission
testing capabilities, with aid from Cummins Engine Company and the
Environmental Protection Agency (EPA). It is important for them to
evaluate their lab and procedures by participating in a round robin
program. A Cummins diesel engine was tested at Cummins Engine
Company, Inc., EPA National Vehicle and Fuel Emissions Laboratory
(NVFEL), and will be tested at the Taiwanese government laboratory.
This report summarizes the emission results produced from the
testing of a Cummins "6C" engine at the EPA NVFEL and Cummins' lab.

•Diesel fuel specification as in CFR 86.1313-90 (b) (2) for 1990
on-road heavy-duty diesel engines.
bMinimum
"Remainder
The fuel was introduced to the engine by transferring it from
the barrel in which it was shipped to the normal laboratory fuel
delivery system by an auxiliary lift pump. It was presented to the
engine at a pressure of 0 to 0.5 psi and a temperature less than
100° F.
The scope of work for this program is as follows (a copy of
the test plan is included in the Appendix):
-------
5
1. Set specifications at rated speed = 2200 rpm
Intake restrictions: 18.5 ± 1 in H20 at rated speed
Exhaust restrictions: 2.4 ± .2 in Hg at rated speed
Intake manifold temp 115 ± 3° F
Process water to CAC 77 ± 4° F
Delta P across CAC < 3 in Hg
Note: CAC = Charge Air Cooler.
2. Run steady state performance
Run 3 lines of data at 1300, 2000, and 2200 rpm
Rated - 2200 rpm and Torque Peak - 1300 rpm
3. Run a torque curve and throttle sweeps
Accessory idle loading (CITT) = "0" ft-lbs
4. Run 3 conditioning cycles - Measure particulates.
5. Ov.ernight soak to 86 °F.
6. Perform a cold cycle - followed by a 20 minute soak.
7. Perform 6 hot cycles with 5 minute soaks between. Oven
extract the particulate filters from the cold and hot
starts.
3. Testing/Results
The engine was set up in EPA/NVFEL test cell #1 and the steady
state performance was evaluated to assure that the engine was
running correctly. The recorded torques and fuel flows at 1300,
2000 and 2200 rpm were compared to Cummins' set-up data (see Table
2) . The data were found to be similar and thus EPA judged the
engine was operating properly.
Next, a torque-map was performed on the engine, followed by
three conditioning cycles. Then, after an overnight soak, a cold-
start and six hot-starts were performed.
Table 3 presents the EPA data from testing the Cummins 6C
correlation engine using the fuel provided by Cummins. A copy of
the individual emissions test summary sheets are included in the
Appendix.

similar testing (using the same engine) was done at Cummins. A
comparison of the composite test results from both laboratories is
presented below.

1. INTRODUCTION:
The Taiwanese Government is in the process of adopting US
mobile source regulations. In turn, they have been developing the
appropriate emission testing capabilities, with aid from Cummins
Engine Company and EPA. It is important for them to evaluate their
lab and procedures by participating in a round robin program. A
Cummins diesel engine will be tested at Cummins Engine Company,
Inc., Southwest Research Institute, EPA NVFEL, and at the Taiwanese
government laboratory. This test plan is for the testing of this
engine at the NVFEL.
2. OBJECTIVE:

(SEE) oven extract all others.
10. Reset the restrictions at 2200 rpm for smoke cycle.
Intake air restriction 25 ± 1 in H20 (smoke)

Additional Information
CVS flow rate is 2200 scfm.
PBS (sample flow) = 0.17% CVS
= 2200 scfm x .17/100 = 3.74 scfm
SDS (secondary dilution flow) = 0.06% CVS
= 2200 scfm * .06/100
= 1.32 scfm
DR (dilution ratio) = (sample + secondary dilution flow)/ sample
