aThe Tier 3 standards in this table do not apply for Category 2 engines at or above 2000 kW with per-cylinder displacement at or above 15.0 liters, or for any Category 2 engines at or above 3700 kW. See §1042.1(c) and paragraphs (a)(6) through (8) of this section for the standards that apply for these engines.
bFor engines subject to the 7.8 g/kW-hr NOX+HC standard, FELs may not be higher than the Tier 1 NOX standards specified in Appendix I of this part.
cThere are no Tier 3 standards for Category 2 engines with per-cylinder displacement at or above 15 and 20 liters with maximum engine power at or above 2000 kW. See paragraphs (a)(6) and (7) of this section for the Tier 4 standards that apply for these engines starting with the 2014 model year.
(4) For Tier 3 engines at or above 19 kW and below 75 kW with displacement below 0.9 L/cyl, you may alternatively certify some or all of your engine families to a PM emission standard of 0.20 g/kW-hr and a NOX+HC emission standard of 5.8 g/kW-hr for 2014 and later model years.
(5) Starting with the 2014 model year, recreational marine engines at or above 3700 kW (with any displacement) must be certified under this part 1042 to the Tier 3 standards specified in this section for 3.5 to 7.0 L/cyl recreational marine engines.
(6) Interim Tier 4 p.m. standards apply for 2014 and 2015 model year engines between 2000 and 3700 kW as specified in this paragraph (a)(6). These engines are considered to be Tier 4 engines.
(i) For Category 1 engines, the Tier 3 p.m. standards from Table 1 to this section continue to apply. PM FELs for these engines may not be higher than the applicable Tier 2 p.m. standards specified in Appendix I of this part.
(ii) For Category 2 engines with per-cylinder displacement below 15.0 liters, the Tier 3 p.m. standards from Table 2 to this section continue to apply. PM FELs for these engines may not be higher than 0.27 g/kW-hr.
(iii) For Category 2 engines with per-cylinder displacement at or above 15.0 liters, the PM standard is 0.34 g/kW-hr for engines at or above 2000 kW and below 3300 kW, and 0.27 g/kW-hr for engines at or above 3300 kW and below 3700 kW. PM FELs for these engines may not be higher than 0.50 g/kW-hr.
(7) Except as described in paragraph (a)(8) of this section, the Tier 4 standards for PM, NOX, and HC emissions are described in the following table:
Table 3 to §1042.101—Tier 4 Standards for Category 2 and Commercial Category 1 Engines at or Above 600 kW
600 ≤ kW < 1400 all 2017+ 0.04 1.8 0.19
1400 ≤ kW < 2000 all 2016+ 0.04 1.8 0.19

15.0 ≤ disp. < 30.0 2014-2015 0.25 1.8 0.19
all 2016+ 0.06 1.8 0.19
aSee paragraph (a)(6) of this section for interim PM standards that apply for model years 2014 and 2015 for engines between 2000 and 3700 kW. The Tier 4 NOX FEL cap for engines at or above 2000 kW and below 3700 kW is 7.0 g/kW-hr. Starting in the 2016 model year, the Tier 4 PM FEL cap for engines at or above 2000 kW and below 3700 kW is 0.34 g/kW-hr.
(8) The following optional provisions apply for complying with the Tier 3 and Tier 4 standards specified in paragraphs (a)(3) through (7) of this section:
(i) You may use NOX credits accumulated through the ABT program to certify Tier 4 engines to a NOX+HC emission standard of 1.9 g/kW-hr instead of the NOX and HC standards that would otherwise apply by certifying your family to a NOX+HC FEL. Calculate the NOX credits needed as specified in subpart H of this part using the NOX+HC emission standard and FEL in the calculation instead of the otherwise applicable NOX standard and FEL. You may not generate credits relative to the alternate standard or certify to the standard without using credits.
(ii) For engines below 1000 kW, you may delay complying with the Tier 4 standards in the 2017 model year for up to nine months, but you must comply no later than October 1, 2017.
(iii) For engines at or above 3700 kW, you may delay complying with the Tier 4 standards in the 2016 model year for up to twelve months, but you must comply no later than December 31, 2016.
(iv) For Category 2 engines at or above 1400 kW, you may alternatively comply with the Tier 3 and Tier 4 standards specified in Table 4 of this section instead of the NOX, HC, NOX+HC, and PM standards specified in paragraphs (a)(3) through (7) of this section. The CO standards specified in paragraph (a)(2) of this section apply without regard to whether you choose this option. If you choose this option, you must do so for all engines at or above 1400 kW in the same displacement category (that is, 7-15, 15-20, 20-25, or 25-30 liters per cylinder) in model years 2012 through 2015.
Table 4 to §1042.101—Optional Tier 3 and Tier 4 Standards for Category 2 Engines at or Above 1400 kW
Tier 3 kW ≥ 1400 2012-2014 0.14 7.8 NOX+HC
Tier 4 1400 ≤ kW ≤ 3700 2015 0.04 1.8 0.19
kW > 3700 2015 0.06 1.8 0.19
(b) Averaging, banking, and trading. You may generate or use emission credits under the averaging, banking, and trading (ABT) program as described in subpart H of this part for demonstrating compliance with NOX, NOX+HC, and PM emission standards for Category 1 and Category 2 engines. You may also use NOX or NOX+HC emission credits to comply with the alternate NOX+HC standard in paragraph (a)(8)(i) of this section. Generating or using emission credits requires that you specify a family emission limit (FEL) for each pollutant you include in the ABT program for each engine family. These FELs serve as the emission standards for the engine family with respect to all required testing instead of the standards specified in paragraph (a) of this section. The FELs determine the not-to-exceed standards for your engine family, as specified in paragraph (c) of this section. Unless otherwise specified, the following FEL caps apply:
(1) FELs for Tier 3 engines may not be higher than the applicable Tier 2 standards specified in Appendix I of this part.
(2) FELs for Tier 4 engines may not be higher than the applicable Tier 3 standards specified in paragraph (a)(3) of this section.
(3) The following FEL caps apply for engines at or above 3700 kW that are not subject to Tier 3 standards under paragraph (a)(3) of this section:
(i) FELs may not be higher than the applicable Tier 1 NOX standards specified in Appendix I of this part before the Tier 4 standards start to apply.
(ii) FELs may not be higher than the applicable Tier 2 NOX+THC standards specified in Appendix I of this part after the Tier 4 standards start to apply.
(c) Not-to-exceed standards. Except as noted in §1042.145(e), exhaust emissions from all engines subject to the requirements of this part may not exceed the not-to-exceed (NTE) standards as follows:
(1) Use the following equation to determine the NTE standards:
(i) NTE standard for each pollutant = STD × M.
STD = The standard specified for that pollutant in this section if you certify without using ABT for that pollutant; or the FEL for that pollutant if you certify using ABT.
M = The NTE multiplier for that pollutant.
(ii) Round each NTE standard to the same number of decimal places as the emission standard.
(2) Determine the applicable NTE zone and subzones as described in §1042.515. Determine NTE multipliers for specific zones and subzones and pollutants as follows:
(i) For marine engines certified using the duty cycle specified in §1042.505(b)(1), except for variable-speed propulsion marine engines used with controllable-pitch propellers or with electrically coupled propellers, apply the following NTE multipliers:
(A) Subzone 1: 1.2 for Tier 3 NOX+HC standards.
(B) Subzone 1: 1.5 for Tier 4 standards and Tier 3 p.m. and CO standards.
(C) Subzone 2: 1.5 for Tier 4 NOX and HC standards and for Tier 3 NOX+HC standards.
(D) Subzone 2: 1.9 for PM and CO standards.
(ii) For recreational marine engines certified using the duty cycle specified in §1042.505(b)(2), except for variable-speed marine engines used with controllable-pitch propellers or with electrically coupled propellers, apply the following NTE multipliers:
(B) Subzone 1: 1.5 for Tier 3 p.m. and CO standards.
(C) Subzones 2 and 3: 1.5 for Tier 3 NOX+HC standards.
(D) Subzones 2 and 3: 1.9 for PM and CO standards.
(iii) For variable-speed marine engines used with controllable-pitch propellers or with electrically coupled propellers that are certified using the duty cycle specified in §1042.505(b)(1), (2), or (3), apply the following NTE multipliers:
(D) Subzone 2: 1.9 for PM and CO standards. However, there is no NTE standard in Subzone 2b for PM emissions if the engine family's applicable standard for PM is at or above 0.07 g/kW-hr.
(iv) For constant-speed engines certified using a duty cycle specified in §1042.505(b)(3) or (4), apply the following NTE multipliers:
(D) Subzone 2: 1.9 for PM and CO standards. However, there is no NTE standard for PM emissions if the engine family's applicable standard for PM is at or above 0.07 g/kW-hr.
(v) For variable-speed auxiliary marine engines certified using the duty cycle specified in §1042.505(b)(5)(ii) or (iii):
(C) Subzone 2: 1.2 for Tier 3 NOX+HC standards.
(D) Subzone 2: 1.5 for Tier 4 standards and Tier 3 p.m. and CO standards. However, there is no NTE standard for PM emissions if the engine family's applicable standard for PM is at or above 0.07 g/kW-hr.
(3) The NTE standards apply to your engines whenever they operate within the NTE zone for an NTE sampling period of at least thirty seconds, during which only a single operator demand set point may be selected. Engine operation during a change in operator demand is excluded from any NTE sampling period. There is no maximum NTE sampling period.
(4) Collect emission data for determining compliance with the NTE standards using the procedures described in subpart F of this part.
(5) You may ask us to accept as compliant an engine that does not fully meet specific requirements under the applicable NTE standards where such deficiencies are necessary for safety.
(d) Fuel types. The exhaust emission standards in this section apply for engines using the fuel type on which the engines in the engine family are designed to operate.
(1) You must meet the numerical emission standards for hydrocarbons in this section based on the following types of hydrocarbon emissions for engines powered by the following fuels:
(i) Alcohol-fueled engines must comply with Tier 3 HC standards based on THCE emissions and with Tier 4 standards based on NMHCE emissions.
(ii) Gaseous-fueled engines must comply with HC standards based on nonmethane-nonethane hydrocarbon emissions.
(iii) Diesel-fueled and all other engines not described in paragraph (d)(1)(i) or (ii) of this section must comply with Tier 3 HC standards based on THC emissions and with Tier 4 standards based on NMHC emissions.
(2) Tier 3 and later engines must comply with the exhaust emission standards when tested using test fuels containing 15 ppm or less sulfur (ultra low-sulfur diesel fuel). Manufacturers may use low-sulfur diesel fuel (without request) to certify an engine otherwise requiring an ultra low-sulfur test fuel; however, emissions may not be corrected to account for the effects of using higher sulfur fuel.
(3) Engines designed to operate using residual fuel must comply with the standards and requirements of this part when operated using residual fuel in addition to complying with the requirements of this part when operated using diesel fuel.
(e) Useful life. Your engines must meet the exhaust emission standards of this section over their full useful life, expressed as a period in years or hours of engine operation, whichever comes first.
(1) The minimum useful life values are as follows, except as specified by paragraph (e)(2) or (3) of this section:
(i) 10 years or 1,000 hours of operation for recreational Category 1 engines
(ii) 5 years or 3,000 hours of operation for commercial engines below 19 kW.
(iii) 7 years or 5,000 hours of operation for commercial engines at or above 19 kW and below 37kW.
(iv) 10 years or 10,000 hours of operation for commercial Category 1 engines at or above 37 kW.
(v) 10 years or 20,000 hours of operation for Category 2 engines.
(3) You may request in your application for certification that we approve a shorter useful life for an engine family. We may approve a shorter useful life, in hours of engine operation but not in years, if we determine that these engines will rarely operate longer than the shorter useful life. If engines identical to those in the engine family have already been produced and are in use, your demonstration must include documentation from such in-use engines. In other cases, your demonstration must include an engineering analysis of information equivalent to such in-use data, such as data from research engines or similar engine models that are already in production. Your demonstration must also include any overhaul interval that you recommend, any mechanical warranty that you offer for the engine or its components, and any relevant customer design specifications. Your demonstration may include any other relevant information. The useful life value may not be shorter than any of the following:
(f) Applicability for testing. The duty-cycle emission standards in this subpart apply to all testing performed according to the procedures in §1042.505, including certification, production-line, and in-use testing. The not-to-exceed standards apply for all testing performed according to the procedures of subpart F of this part.
[73 FR 37243, June 30, 2008, as amended at 73 FR 59192, Oct. 8, 2008; 74 FR 8425, Feb. 24, 2009; 75 FR 22996, Apr. 30, 2010; 81 FR 74142, Oct. 25, 2016]
(a) There are no evaporative emission standards for diesel-fueled engines, or engines using other nonvolatile or nonliquid fuels (for example, natural gas).
(b) If an engine uses a volatile liquid fuel, such as methanol, the engine's fuel system and the vessel in which the engine is installed must meet the evaporative emission requirements of 40 CFR part 1045 that apply with respect to spark-ignition engines. Manufacturers subject to evaporative emission standards must meet the requirements of 40 CFR 1045.112 as described in 40 CFR part 1060 and do all the following things in the application for certification:
(1) Describe how evaporative emissions are controlled.
(2) Present test data to show that fuel systems and vessels meet the evaporative emission standards we specify in this section if you do not use design-based certification under 40 CFR 1060.240. Show these figures before and after applying deterioration factors, where applicable.
[73 FR 59193, Oct. 8, 2008]
(2) The onboard computer log must record in nonvolatile computer memory all incidents of engine operation with inadequate reductant injection or reductant quality. Use good engineering judgment to ensure that the operator can readily access the information to submit the report required by §1042.660. For example, you may meet this requirement by documenting the incident in a text file that can be downloaded or printed by the operator.
(3) SCR systems must also conform to the provisions of paragraph (d) of this section if they are equipped with on-off controls as allowed under §1042.115(g).
(c) You may equip your engine with other diagnostic features. If you do, they must be designed to allow us to read and interpret the codes. Note that §§1042.115 and 1042.205 require that you provide us any information needed to read, record, and interpret all the information broadcast by an engine's onboard computers and electronic control units.
(d) For Category 3 engines equipped with on-off NOX controls (as allowed by §1042.115(g)), you must also equip your engine to continuously monitor NOX concentrations in the exhaust. See §1042.650 to determine if this requirement applies for a given Category 1 or Category 2 engine. For measurement technologies involving discrete sampling events, measurements are considered continuous if they repeat at least once every 60 seconds; we may approve a longer sampling period if it is necessary or appropriate for sufficiently accurate measurements. Describe your system for onboard NOX measurements in your application for certification. Use good engineering judgment to alert operators if measured NOX concentrations indicate malfunctioning emission controls. Record any such operation in nonvolatile computer memory. You are not required to monitor NOX concentrations during operation for which the emission controls may be disabled under §1042.115(g). For the purpose of this paragraph (d), “malfunctioning emission controls” means any condition in which the measured NOX concentration exceeds the highest value expected when the engine is in compliance with the installed engine standard of §1042.104(g). Use good engineering judgment to determine these expected values during production-line testing of the engine using linear interpolation between test points and accounting for the degree to which the cycle-weighted emissions of the engine are below the standard. You may also use additional intermediate test points measured during the production-line test. Note that the provisions of paragraph (a) of this section also apply for SCR systems covered by this paragraph (d). For engines subject to both the provisions of paragraph (a) of this section and this paragraph (d), use good engineering judgment to integrate diagnostic features to comply with both paragraphs. For example, engines may use on-off NOX controls to disable certain emission control functions only if the diagnostic system indicates that the monitoring described in this paragraph (d) is active.
Give the ultimate purchaser of each new engine written instructions for properly maintaining and using the engine, including the emission control system, as described in this section. The maintenance instructions also apply to service accumulation on your emission-data engines as described in §1042.245 and in 40 CFR part 1065. The restrictions specified in paragraphs (a) through (e) of this section related to allowable maintenance apply only to Category 1 and Category 2 engines. Manufacturers may specify any maintenance for Category 3 engines.
(i) You present data showing that any lack of maintenance that increases emissions also unacceptably degrades the engine's performance.
(2) For engines below 130 kW, you may not schedule critical emission-related maintenance more frequently than the following minimum intervals, except as specified in paragraphs (a)(4), (b), and (c) of this section:
(i) For EGR-related filters and coolers, DEF filters, crankcase ventilation valves and filters, and fuel injector tips (cleaning only), the minimum interval is 1,500 hours.
(ii) For the following components, including associated sensors and actuators, the minimum interval is 3,000 hours: Fuel injectors, turbochargers, catalytic converters, electronic control units, particulate traps, trap oxidizers, components related to particulate traps and trap oxidizers, EGR systems (including related components, but excluding filters and coolers), and other add-on components. For particulate traps, trap oxidizers, and components related to either of these, maintenance is limited to cleaning and repair only.
(3) For Category 1 and Category 2 engines at or above 130 kW, you may not schedule critical emission-related maintenance more frequently than the following minimum intervals, except as specified in paragraphs (a)(4), (b), and (c) of this section:
(ii) For the following components, including associated sensors and actuators, the minimum interval is 4500 hours: Fuel injectors, turbochargers, catalytic converters, electronic control units, particulate traps, trap oxidizers, components related to particulate traps and trap oxidizers, EGR systems (including related components, but excluding filters and coolers), and other add-on components. For particulate traps, trap oxidizers, and components related to either of these, maintenance is limited to cleaning and repair only.
(4) We may approve shorter maintenance intervals than those listed in paragraph (a)(3) of this section where technologically necessary.
(5) If your engine family has an alternate useful life under §1042.101(e) that is shorter than the period specified in paragraph (a)(2) or (a)(3) of this section, you may not schedule critical emission-related maintenance more frequently than the alternate useful life, except as specified in paragraph (c) of this section.
(c) Special maintenance. You may specify more frequent maintenance to address problems related to special situations, such as atypical engine operation. You must clearly state that this additional maintenance is associated with the special situation you are addressing. You may also address maintenance of low-use engines (such as recreational or stand-by engines) by specifying the maintenance interval in terms of calendar months or years in addition to your specifications in terms of engine operating hours. All special maintenance instructions must be consistent with good engineering judgment. We may disapprove your maintenance instructions if we determine that you have specified special maintenance steps to address maintenance that is unlikely to occur in use, or engine operation that is not atypical. For example, this paragraph (c) does not allow you to design engines that require special maintenance for a certain type of expected operation. If we determine that certain maintenance items do not qualify as special maintenance under this paragraph (c), you may identify this as recommended additional maintenance under paragraph (b) of this section.
(d) Noncritical emission-related maintenance. Subject to the provisions of this paragraph (d), you may schedule any amount of emission-related inspection or maintenance that is not covered by paragraph (a) of this section (that is, maintenance that is neither explicitly identified as critical emission-related maintenance, nor that we approve as critical emission-related maintenance). Noncritical emission-related maintenance generally includes maintenance on the components we specify in 40 CFR part 1068, Appendix I that is not covered in paragraph (a) of this section. You must state in the owners manual that these steps are not necessary to keep the emission-related warranty valid. If operators fail to do this maintenance, this does not allow you to disqualify those engines from in-use testing or deny a warranty claim. Do not take these inspection or maintenance steps during service accumulation on your emission-data engines.
(e) Maintenance that is not emission-related. For maintenance unrelated to emission controls, you may schedule any amount of inspection or maintenance. You may also take these inspection or maintenance steps during service accumulation on your emission-data engines, as long as they are reasonable and technologically necessary. This might include adding engine oil, changing air, fuel, or oil filters, servicing engine-cooling systems, and adjusting idle speed, governor, engine bolt torque, valve lash, or injector lash. You may not perform this nonemission-related maintenance on emission-data engines more often than the least frequent intervals that you recommend to the ultimate purchaser.
(f) Source of parts and repairs. State clearly in your written maintenance instructions that a repair shop or person of the owner's choosing may maintain, replace, or repair emission control devices and systems. Your instructions may not require components or service identified by brand, trade, or corporate name. Also, do not directly or indirectly condition your warranty on a requirement that the engine be serviced by your franchised dealers or any other service establishments with which you have a commercial relationship. You may disregard the requirements in this paragraph (f) if you do one of two things:
(1) Each affected component was not in general use on similar engines before the applicable dates shown in paragraph (6) of the definition of “new marine engine” in §1042.901.
(e) Delayed compliance with NTE standards. Engines below 56 kW may delay complying with the NTE standards specified in §1042.101(c) until the 2013 model year. Engines at or above 56 kW and below 75 kW may delay complying with the NTE standards specified in §1042.101(c) until the 2012 model year.
