PART 1051_CONTROL OF EMISSIONS FROM RECREATIONAL ENGINES AND VEHICLES

--Table of Contents

 

                  Subpart A_Overview and Applicability

 

Sec.  1051.20  May I certify a recreational engine instead of the vehicle?



    (a) You may certify engines sold separately from vehicles in either 

of two cases:

    (1) If you manufacture recreational engines but not recreational 

vehicles, you may ask to certify the engine alone. In your request, 

explain why you cannot certify the entire vehicle.

    (2) If you manufacture complete recreational vehicles containing 

engines you also sell separately, you may ask to certify all these 

engines in a single engine family or in separate engine families.

    (b) If you certify an engine under this section, you must use the 

test procedures in subpart F of this part. If the test procedures 

require vehicle testing, use good engineering judgment to install the 

engine in an appropriate vehicle for measuring emissions.

    (c) If we allow you to certify recreational engines, the vehicles 

must meet the applicable emission standards (including evaporative 

emission standards) with the engines installed in the appropriate 

vehicles. You must prepare installation instructions as described in 

Sec.  1051.130 and use good engineering judgment so that the engines 

will meet emission standards after proper installation in the vehicle.

    (d) Identify and label engines you produce under this section 

consistent with the requirements of Sec.  1051.135. On the emission 

control information label, identify the manufacturing date of the engine 

rather than the vehicle.

    (e) You may not use the provisions of this section to circumvent or 

reduce the stringency of this part's standards or other requirements.

    (f) If you certify under paragraph (a)(1) of this section, you may 

ask us to

allow you to perform production-line testing on the engine. If you 

certify under paragraph (a)(2) of this section, use good engineering 

judgment to ensure that these engines are produced in the same manner as 

the engines you produce for your vehicles, so that your production-line 

testing results under subpart D of this part would apply to them.
