Sec.  1039.205  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.  

1039.201(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 engine's design and emission controls. List the fuel 

type on which your engines are designed to operate (for example, ultra 

low-sulfur diesel fuel). List each distinguishable engine configuration 

in the engine family. For

each engine configuration, list the maximum engine power and the range 

of values for maximum engine power resulting from production tolerances, 

as described in Sec.  1039.140.

    (b) Explain how the emission-control system operates. Describe in 

detail all system components for controlling exhaust emissions, 

including all auxiliary-emission control devices (AECDs) and all fuel-

system components you will install on any production or test 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 equipment-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 equipment:

    (i) Identify the engine and/or equipment 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 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.  

1039.501).

    (f) Describe how you operated the emission-data engine before 

testing, including the duty cycle and the number of engine operating 

hours 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 nonroad engine (see Sec.  1039.125).

    (j) Include the emission-related installation instructions you will 

provide if someone else installs your engines in a piece of nonroad 

equipment (see Sec.  1039.130).

    (k) Describe your emission control information label (see Sec.  

1039.135).

    (l) Identify the emission standards or FELs to which you are 

certifying engines in the engine family. Identify the ambient operating 

regions that will apply for NTE testing under Sec.  1039.101(e)(4).

    (m) Identify the engine family's deterioration factors and describe 

how you developed them (see Sec.  1039.245). Present any emission test 

data you used for this.

    (n) State that you operated your emission-data engines 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 for hydrocarbons (such as NMHC or THCE, as 

applicable), NOX, PM, and CO on an emission-data 

engine to show your engines meet the applicable duty-cycle emission 

standards we specify in Sec.  1039.101. Show emission data figures 

before and after applying adjustment factors for regeneration and 

deterioration factors for each engine. Present emission data to show 

that you meet any applicable smoke standards we specify in Sec.  

1039.105. If we specify more than one grade of any fuel type (for 

example, high-sulfur and low-sulfur diesel fuel), you need to submit 

test data only for one grade, unless the regulations of this part 

specify otherwise for your engine. Note that Sec.  1039.235 allows you 

to submit an application in certain cases without new emission data.

    (p) State that all the engines in the engine family comply with the 

not-to-exceed emission standards we specify in subpart B of this part 

for all normal operation and use when tested as specified in Sec.  

1039.515. Describe any relevant testing, engineering analysis, or other 

information in sufficient detail to support your statement.

    (q) For engines above 560 kW, include information showing how your 

emission controls will function during normal in-use transient 

operation. For example, this might include the following:

    (1) Emission data from transient testing of engines using 

measurement systems designed for measuring in-use emissions.

    (2) Comparison of the engine design for controlling transient 

emissions with that from engines for which you have emission data over 

the transient duty cycle for certification.

    (3) Detailed descriptions of control algorithms and other design 

parameters for controlling transient emissions.

    (r) 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.

    (s) Describe all adjustable operating parameters (see Sec.  

1039.115(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.

    (t) Provide the information to read, record, and interpret all the 

information broadcast by an engine's onboard computers and electronic 

control units. State that, upon request, you will give us any hardware, 

software, or tools we would need to do this. If you broadcast a 

surrogate parameter for torque values, you must provide us what we need 

to convert these into torque units. You may reference any appropriate 

publicly



[[Page 502]]



released standards that define conventions for these messages and 

parameters. Format your information consistent with publicly released 

standards.

    (u) 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.

    (v) State whether your certification is limited for certain engines. 

If this is the case, describe how you will prevent use of these engines 

in applications for which they are not certified. This applies for 

engines such as the following:

    (1) Constant-speed engines.

    (2) Engines used for transportation refrigeration units that you 

certify under the provisions of Sec.  1039.645.

    (3) Hand-startable engines certified under the provisions of Sec.  

1039.101(c).

    (4) Engines above 560 kW that are not certified to emission 

standards for generator-set engines.

    (w) Unconditionally certify that all the engines in the engine 

family comply with the requirements of this part, other referenced parts 

of the CFR, and the Clean Air Act.

    (x) Include estimates of U.S.-directed production volumes.

    (y) Include the information required by other subparts of this part. 

For example, include the information required by Sec.  1039.725 if you 

participate in the ABT program.

    (z) Include other applicable information, such as information 

specified in this part or 40 CFR part 1068 related to requests for 

exemptions.
