                  Subpart C_Certifying Engine Families
 
Sec. 1051.205  What must I include in my application?

    In your application, do all the following things unless we ask you 
to send us less information:
    (a) Describe the engine family's specifications and other basic 
parameters of the vehicle design. List the types of fuel you intend to 
use to certify the engine family (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 systems operate.
    (1) Describe in detail all the system components for controlling 
exhaust emissions, including auxiliary emission-control devices and all 
fuel-system components you will install on any production or test 
vehicle or engine. Explain why any auxiliary emission-control devices 
are not defeat devices (see Sec. 1051.115(f)). Do not include detailed 
calibrations for components unless we ask for them.
    (2) Describe the evaporative emission controls.
    (c) Describe the vehicles or engines you selected for testing and 
the reasons for selecting them.
    (d) Describe any special or alternate test procedures you used (see 
Sec. 1051.501).
    (e) Describe how you operated the engine or vehicle prior to 
testing, including the duty cycle and the number of engine operating 
hours used to stabilize emission levels, and any scheduled maintenance 
you performed.
    (f) List the specifications of the test fuels to show that they fall 
within the required ranges.
    (g) Identify the engine family's useful life.
    (h) Propose maintenance and use instructions for the ultimate buyer 
of each new vehicle (see Sec. 1051.125).
    (i) Propose emission-related installation instructions if you sell 
engines for someone else to install in a vehicle (see Sec. 1051.130).
    (j) Propose an emission control information label.
    (k) Present emission data to show that you meet emission standards.
    (1) Present exhaust emission data for HC, NOX (as 
applicable), and CO on a

test vehicle or engine to show your vehicles meet the emission standards 
we specify in subpart B of this part. Show these figures before and 
after applying deterioration factors for each vehicle or engine. Include 
test data for each type of fuel from part 1065, subpart C, of this 
chapter on which you intend for vehicles in the engine family to operate 
(for example, gasoline, liquefied petroleum gas, methanol, or natural 
gas). If we specify more than one grade of any fuel type (for example, a 
summer grade and winter grade of gasoline), you only need to submit test 
data for one grade, unless the regulations of this part explicitly 
specify otherwise for your vehicle.
    (2) Present evaporative test data for HC to show your vehicles meet 
the evaporative emission standards we specify in subpart B of this part. 
Show these 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 1051.245 allows you to submit an 
application in certain cases without new emission data.
    (l) Report all test results, including those from invalid tests or 
from any nonstandard tests (such as measurements based on exhaust 
concentrations in parts per million).
    (m) Identify the engine family's deterioration factors and describe 
how you developed them. Present any emission test data you used for 
this.
    (n) Describe all adjustable operating parameters and other 
adjustments (see Sec. 1051.115 (c) and (d)), including the following:
    (1) The nominal or recommended setting.
    (2) The intended physically adjustable range, including production 
tolerances if they affect the range.
    (3) The limits or stops used to establish adjustable ranges.
    (4) The air-fuel ratios or jet chart specified in Sec. 1051.115(d).
    (o) State that you operated your test vehicles or engines according 
to the specified procedures and test parameters using the fuels 
described in the application to show you meet the requirements of this 
part.
    (p) State unconditionally that all the vehicles (and/or engines) in 
the engine family comply with the requirements of this part, other 
referenced parts, and the Clean Air Act.
    (q) Include estimates of U.S.-directed production volumes.
    (r) Show us how to modify your production vehicles to measure 
emissions in the field (see Sec. 1051.115).
    (s) Add other information to help us evaluate your application if we 
ask for it.
