This section describes how to prepare and test production-line engines. You must assemble the test engine in a way that represents the assembly procedures for other engines in the engine family. You must ask us to approve any deviations from your normal assembly procedures for other production engines in the engine family.
(a) Test procedures. Test your production-line engines using the applicable testing procedures in subpart F of this part to show you meet the duty-cycle emission standards in subpart B of this part. For Category 1 and Category 2 engines, the not-to-exceed standards apply for this testing of Category 1 and Category 2 engines, but you need not do additional testing to show that production-line engines meet the not-to-exceed standards. The mode cap standards apply for the testing of Category 3 engines.
(b) Modifying a test engine. Once an engine is selected for testing (see §1042.310), you may adjust, repair, prepare, or modify it or check its emissions only if one of the following is true:
(1) You document the need for doing so in your procedures for assembling and inspecting all your production engines and make the action routine for all the engines in the engine family.
(2) This subpart otherwise specifically allows your action.
(3) We approve your action in advance.
(c) Engine malfunction. If an engine malfunction prevents further emission testing, ask us to approve your decision to either repair the engine or delete it from the test sequence.
(d) Setting adjustable parameters. Before any test, we may require you to adjust any adjustable parameter on a Category 1 engine to any setting within its physically adjustable range. We may adjust or require you to adjust any adjustable parameter on a Category 2 or Category 3 engine to any setting within its specified adjustable range.
(1) We may require you to adjust idle speed outside the physically adjustable range as needed, but only until the engine has stabilized emission levels (see paragraph (e) of this section). We may ask you for information needed to establish an alternate minimum idle speed.
(2) We may specify adjustments within the physically adjustable range or the specified adjustable range by considering their effect on emission levels. We may also consider how likely it is that someone will make such an adjustment with in-use engines.
(e) Stabilizing emission levels. You may stabilize emission levels (or establish a Green Engine Factor for Category 2 engines) before you test production-line engines, as follows:
(1) You may stabilize emission levels by operating the engine in a way that represents the way production engines will be used, using good engineering judgment, for no more than the greater of two periods:
(i) 300 hours.
(ii) The number of hours you operated your emission-data engine for certifying the engine family (see 40 CFR part 1065, subpart E, or the applicable regulations governing how you should prepare your test engine).
(2) For Category 2 or Category 3 engines, you may ask us to approve a Green Engine Factor for each regulated pollutant for each engine family. Use the Green Engine Factor to adjust measured emission levels to establish a stabilized low-hour emission level.
(f) Damage during shipment. If shipping an engine to a remote facility for production-line testing makes necessary an adjustment or repair, you must wait until after the initial emission test to do this work. We may waive this requirement if the test would be impossible or unsafe, or if it would permanently damage the engine. Report to us in your written report under §1042.345 all adjustments or repairs you make on test engines before each test.
(g) Retesting after invalid tests. You may retest an engine if you determine an emission test is invalid under subpart F of this part. Explain in your written report reasons for invalidating any test and the emission results from all tests. If we determine that you improperly invalidated a test, we may require you to ask for our approval for future testing before substituting results of the new tests for invalid ones.
(a) If you have a production-line engine with final deteriorated test results exceeding one or more emission standards (see §1042.315(a)), the certificate of conformity is automatically suspended for that failing engine. You must take the following actions before your certificate of conformity can cover that engine:
(1) Correct the problem and retest the engine to show it complies with all emission standards.
(2) Include the test results and describe the remedy for each engine in the written report required under §1042.345.
(b) You may request to amend the application for certification to raise the FEL of the entire engine family at this point (see §1042.225).
(c) For catalyst-equipped engines, you may ask us to allow you to exclude an initial failed test if all of the following are true:
(2) The engine met all emission standards when retested after degreening the catalyst.
(a) We may suspend your certificate of conformity for an engine family if it fails under §1042.315. The suspension may apply to all facilities producing engines from an engine family, even if you find noncompliant engines only at one facility.
(b) We will tell you in writing if we suspend your certificate in whole or in part. We will not suspend a certificate until at least 15 days after the engine family fails. The suspension is effective when you receive our notice.
(c) Up to 15 days after we suspend the certificate for an engine family, you may ask for a hearing (see §1042.920). If we agree before a hearing occurs that we used erroneous information in deciding to suspend the certificate, we will reinstate the certificate.
(d) Section 1042.335 specifies steps you must take to remedy the cause of the engine family's production-line failure. All the engines you have produced since the end of the last test period are presumed noncompliant and should be addressed in your proposed remedy. We may require you to apply the remedy to engines produced earlier if we determine that the cause of the failure is likely to have affected the earlier engines.
(e) You may request to amend the application for certification to raise the FEL of the entire engine family before or after we suspend your certificate as described in §1042.225(f). We will approve your request if the failure is not caused by a defect and it is clear that you used good engineering judgment in establishing the original FEL.
You may sell engines that you produce after we suspend the engine family's certificate of conformity under §1042.315 only if one of the following occurs:
(a) You test each engine you produce and show it complies with emission standards that apply.
(b) We conditionally reinstate the certificate for the engine family. We may do so if you agree to recall all the affected engines and remedy any noncompliance at no expense to the owner if later testing shows that the engine family still does not comply.
(a) Send us a written report asking us to reinstate your suspended certificate. In your report, identify the reason for noncompliance, propose a remedy for the engine family, and commit to a date for carrying it out. In your proposed remedy include any quality control measures you propose to keep the problem from happening again.
(b) Give us data from production-line testing that shows the remedied engine family complies with all the emission standards that apply.
(a) We may revoke your certificate for an engine family in the following cases:
(1) You do not meet the reporting requirements.
(2) Your engine family fails to comply with the requirements of this subpart and your proposed remedy to address a suspended certificate under §1042.325 is inadequate to solve the problem or requires you to change the engine's design or emission control system.
(b) To sell engines from an engine family with a revoked certificate of conformity, you must modify the engine family and then show it complies with the requirements of this part.
(1) If we determine your proposed design change may not control emissions for the engine's full useful life, we will tell you within five working days after receiving your report. In this case we will decide whether production-line testing will be enough for us to evaluate the change or whether you need to do more testing.
(2) Unless we require more testing, you may show compliance by testing production-line engines as described in this subpart.
(3) We will issue a new or updated certificate of conformity when you have met these requirements.
