Subpart C_Certifying Engine Families
Sec. 1051.205 What must I include in my application?
This section specifies the information that must be in your
application, unless we ask you to include less information under Sec.
1051.201(c). We may require you to provide additional information to
evaluate your application.
(a) Describe the engine family's specifications and other basic
parameters of the vehicle's design and emission controls. List the fuel
type on which your engines are designed to operate (for example,
gasoline, liquefied petroleum gas, methanol, or natural gas). List
vehicle configurations and model names that are included in the engine
family.
(b) Explain how the emission-control system operates. Describe the
evaporative emission controls. Also describe in detail all system
components for
[[Page 630]]
controlling exhaust emissions, including all auxiliary-emission control
devices (AECDs) and all fuel-system components you will install on any
production or test vehicle or engine. Identify the part number of each
component you describe. For this paragraph (b), treat as separate AECDs
any devices that modulate or activate differently from each other.
Include all the following:
(1) Give a general overview of the engine, the emission-control
strategies, and all AECDs.
(2) Describe each AECD's general purpose and function.
(3) Identify the parameters that each AECD senses (including
measuring, estimating, calculating, or empirically deriving the values).
Include vehicle-based parameters and state whether you simulate them
during testing with the applicable procedures.
(4) Describe the purpose for sensing each parameter.
(5) Identify the location of each sensor the AECD uses.
(6) Identify the threshold values for the sensed parameters that
activate the AECD.
(7) Describe the parameters that the AECD modulates (controls) in
response to any sensed parameters, including the range of modulation for
each parameter, the relationship between the sensed parameters and the
controlled parameters and how the modulation achieves the AECD's stated
purpose. Use graphs and tables, as necessary.
(8) Describe each AECD's specific calibration details. This may be
in the form of data tables, graphical representations, or some other
description.
(9) Describe the hierarchy among the AECDs when multiple AECDs sense
or modulate the same parameter. Describe whether the strategies interact
in a comparative or additive manner and identify which AECD takes
precedence in responding, if applicable.
(10) Explain the extent to which the AECD is included in the
applicable test procedures specified in subpart F of this part.
(11) Do the following additional things for AECDs designed to
protect engines or vehicles:
(i) Identify the engine and/or vehicle design limits that make
protection necessary and describe any damage that would occur without
the AECD.
(ii) Describe how each sensed parameter relates to the protected
components' design limits or those operating conditions that cause the
need for protection.
(iii) Describe the relationship between the design limits/parameters
being protected and the parameters sensed or calculated as surrogates
for those design limits/parameters, if applicable.
(iv) Describe how the modulation by the AECD prevents engines and/or
equipment from exceeding design limits.
(v) Explain why it is necessary to estimate any parameters instead
of measuring them directly and describe how the AECD calculates the
estimated value, if applicable.
(vi) Describe how you calibrate the AECD modulation to activate only
during conditions related to the stated need to protect components and
only as needed to sufficiently protect those components in a way that
minimizes the emission impact.
(c) [Reserved]
(d) Describe the vehicles or engines you selected for testing and
the reasons for selecting them.
(e) Describe the test equipment and procedures that you used,
including any special or alternate test procedures you used (see Sec.
1051.501).
(f) Describe how you operated the emission-data vehicle before
testing, including the duty cycle and the extent of engine operation
used to stabilize emission levels. Explain why you selected the method
of service accumulation. Describe any scheduled maintenance you did.
(g) List the specifications of the test fuel to show that it falls
within the required ranges we specify in 40 CFR part 1065.
(h) Identify the engine family's useful life.
(i) Include the maintenance instructions you will give to the
ultimate purchaser of each new vehicle (see Sec. 1051.125).
(j) Include the emission-related installation instructions you will
provide if someone else installs your engines in a vehicle (see Sec.
1051.130).
[[Page 631]]
(k) Describe the labels you create to meet the requirements of Sec.
1051.135.
(l) Identify the exhaust emission standards or FELs to which you are
certifying engines in the engine family.
(m) Identify the engine family's deterioration factors and describe
how you developed them (see Sec. 1051.243 and Sec. 1051.245). Present
any emission test data you used for this.
(n) State that you operated your emission-data vehicles as described
in the application (including the test procedures, test parameters, and
test fuels) to show you meet the requirements of this part.
(o) Present emission data to show that you meet emission standards,
as follows:
(1) Present emission data for hydrocarbons (such as NMHC or THCE, as
applicable), NOX, and CO on an emission-data vehicle to show
your vehicles meet the applicable exhaust emission standards we specify
in subpart B of this part. Show emission figures before and after
applying deterioration factors for each pollutant and for each vehicle
or engine. If we specify more than one grade of any fuel type (for
example, a summer grade and winter grade of gasoline), you need to
submit test data only for one grade, unless the regulations of this part
specify otherwise for your engine.
(2) Present evaporative test data for hydrocarbons to show your
vehicles meet the evaporative emission standards we specify in subpart B
of this part. Show emission figures before and after applying
deterioration factors for each vehicle or engine, where applicable. If
you did not perform the testing, identify the source of the test data.
(3) Note that Sec. 1051.235 and Sec. 1051.245 allow you to submit
an application in certain cases without new emission data.
(p) Report all test results, including those from invalid tests or
from any other tests, whether or not they were conducted according to
the test procedures of subpart F of this part. If you measure
CO2, report those emission levels. We may ask you to send
other information to confirm that your tests were valid under the
requirements of this part and 40 CFR part 1065.
(q) Describe all adjustable operating parameters (see Sec.
1051.115(e)), including production tolerances. Include the following in
your description of each parameter:
(1) The nominal or recommended setting.
(2) The intended physically adjustable range.
(3) The limits or stops used to establish adjustable ranges.
(4) Information showing why the limits, stops, or other means of
inhibiting adjustment are effective in preventing adjustment of
parameters on in-use engines to settings outside your intended
physically adjustable ranges.
(r) Confirm that your emission-related installation instructions
specify how to ensure that sampling of exhaust emissions will be
possible after engines are installed in equipment and placed in service.
If this cannot be done by simply adding a 20-centimeter extension to the
exhaust pipe, show how to sample exhaust emissions in a way that
prevents diluting the exhaust sample with ambient air.
(s) Unconditionally certify that all the vehicles and/or engines in
the engine family comply with the requirements of this part, other
referenced parts of the CFR, and the Clean Air Act.
(t) Include estimates of U.S.-directed production volumes.
(u) Include the information required by other subparts of this part.
For example, include the information required by Sec. 1051.725 if you
participate in the ABT program.
(v) Include other applicable information, such as information
specified in this part or 40 CFR part 1068 related to requests for
exemptions.
(w) Name an agent for service of process located in the United
States. Service on this agent constitutes service on you or any of your
officers or employees for any action by EPA or otherwise by the United
States related to the requirements of this part.
