(3) Heavy-duty engines. (i) A permanent legible label shall be affixed to the engine in a position in which it will be readily visible after installation in the vehicle.

(ii) The label shall be attached to an engine part necessary for normal engine operation and not normally requiring replacement during engine life.

(iii) The label shall contain the following information lettered in the English language in block letters and numerals which shall be of a color that contrasts with the background of the label:

(A) The label heading: “Important Engine Information.”;

(B) The full corporate name and trademark of the manufacturer; though the label may identify another company and use its trademark instead of the manufacturer's as long as the manufacturer complies with the branding provisions of 40 CFR 1068.45.

(C) Engine displacement (in cubic inches or liters) and engine family and model designations;

(E) Engine specifications and adjustments as recommended by the manufacturer. These specifications should indicate the proper transmission position during tune-up and what accessories (e.g., air conditioner), if any, should be in operation;

(F) For Otto-cycle engines the label should include the idle speed, ignition timing, and the idle air-fuel mixture setting procedure and value (e.g., idle CO, idle air-fuel ratio, idle speed drop), and valve lash;

(G) For diesel engines the label should include the advertised hp at rpm, fuel rate at advertised hp in mm 3/stroke, valve lash, initial injection timing, and idle speed;

(H) The prominent statement: “This engine conforms to U.S. EPA regulations applicable to XXXX Model Year New Heavy-Duty Engines.”;

(I) If the manufacturer has an alternate useful life period under the provisions of § 86.094-21(f), the prominent statement: “This engine has been certified to meet U.S. EPA standards for a useful-life period of XXX miles or XXX hours of operation, whichever occurs first. This engine's actual life may vary depending on its service application.” The manufacturer may alter this statement only to express the assigned alternate useful life in terms other than miles or hours (e.g., years, or hours only);

(J) For diesel engines, the prominent statement: “This engine has a primary intended service application as a XXX heavy-duty engine.” (The primary intended service applications are light, medium, and heavy, as defined in § 86.090-2.);

(L) For diesel engines which are included in the diesel heavy-duty particulate averaging program, the family particulate emission limit to which the engine is certified;

(M) For any heavy-duty engines which are included in the heavy-duty NOX averaging program, the family NOX emission limit to which the engine is certified;

(N) Engines granted final admission under § 85.1505 of this chapter must comply with the labeling requirements contained in § 85.1510 of this chapter.

(O) For engines with one or more approved AECDs for emergency vehicle applications under paragraph (4) of the definition of “defeat device” in § 86.004-2, the statement: “THIS ENGINE IS FOR INSTALLATION IN EMERGENCY VEHICLES ONLY.”

(iv) The label may be made up of one or more pieces: Provided, That all pieces are permanently attached to the same engine or vehicle part as applicable.

(4) Heavy-duty vehicles employing a fuel or fuels covered by evaporative emission standards. This paragraph (a)(4) applies for vehicles subject to evaporative emission standards under this subpart, as described in § 86.016-1(a)(4).

(ii) The label shall be affixed by the vehicle manufacturer who has been issued the Certificate of Conformity for such vehicle, in such a manner that it cannot be removed without destroying or defacing the label. The label shall not be affixed to any equipment which is easily detached from such vehicle.

(iii) The label shall contain the following information lettered in the English language in block letters and numerals, which shall be of a color that contrasts with the background of the label:

(A) The label heading: Vehicle Emission Control Information;

(B) Full corporate name and trademark of manufacturer;

(D) The maximum nominal fuel tank capacity (in gallons), as specified in 40 CFR 1037.135; and

(E) An unconditional statement of compliance with the appropriate model year U.S. Environmental Protection Agency regulations which apply to XXX-fueled heavy-duty vehicles.

(F) Vehicles granted final admission under § 85.1505 of this chapter must comply with the labeling requirements contained in § 85.1510 of this chapter.

(c) Vehicles powered by model year 2007 through 2013 diesel-fueled engines must include permanent, readily visible labels on the dashboard (or instrument panel) and near all fuel inlets that state “Use Ultra Low Sulfur Diesel Fuel Only”; or “Ultra Low Sulfur Diesel Fuel Only”.

(d)-(g) [Reserved]

(h) Notification of nonconformance penalty. (1) Light-duty trucks and heavy-duty vehicles and engines for which nonconformance penalties are to be paid in accordance with § 86.1113-87(b) shall have the following information printed on the label required in paragraph (a) of this section. The manufacturer shall begin labeling production engines or vehicles within 10 days after the completion of the PCA.

The compliance level (or new emission standard) for this engine/vehicle is XXX.” (The manufacturer shall insert the applicable pollutant and compliance level calculated in accordance with § 86.1112-87(a).)

(2) If a manufacturer introduces an engine or vehicle into commerce prior to the compliance level determination of § 86.1112-87(a), it shall provide the engine or vehicle owner with a label as described above to be affixed in a location in proximity to the label required in paragraph (a) of this section within 30 days of the completion of the PCA.
