Sec.  1051.120  What emission-related warranty requirements apply to me?

    (a) General requirements. You must warrant to the ultimate purchaser 
and each subsequent purchaser that the new engine, including all parts 
of its emission-control system, meets two conditions:
    (1) It is designed, built, and equipped so it conforms at the time 
of sale to the ultimate purchaser with the requirements of this part.
    (2) It is free from defects in materials and workmanship that may 
keep it from meeting these requirements.
    (b) Warranty period. Your emission-related warranty must be valid 
for at least 50 percent of the vehicle's minimum useful life in 
kilometers or hours of engine operation (where applicable), or at least 
30 months, whichever comes first. You may offer an emission-related 
warranty more generous than we require. The emission-related warranty 
for the engine may not be shorter than any published warranty you offer 
without charge for the engine. Similarly, the emission-related warranty 
for any component may not be shorter than any published warranty you 
offer without charge for that component. If a vehicle has no odometer, 
base warranty periods in this paragraph (b) only on the vehicle's age 
(in years). The warranty period begins when the engine is placed into 
service.
    (c) Components covered. The emission-related warranty covers all 
components whose failure would increase an engine's emissions of any 
pollutant. This includes components listed in 40 CFR part 1068, Appendix 
I, and components from any other system you develop to control 
emissions. The emission-related warranty covers these components even if 
another company produces the component. Your emission-related warranty 
does not cover components whose failure would not increase an engine's 
emissions of any pollutant.
    (d) Limited applicability. You may deny warranty claims under this 
section if the operator caused the problem through improper maintenance 
or use, as described in 40 CFR 1068.115. You may ask us to allow you to 
exclude from your emission-related warranty certified vehicles that have 
been used

significantly for competition, especially certified motorcycles that 
meet at least four of the criteria in Sec.  1051.620(b)(1).
    (e) Owners manual. Describe in the owners manual the emission-
related warranty provisions from this section that apply to the engine.
