CO2 entries in the test report (Annex 2, Appendix A.1, paras. 10.3.1. and 10.3.4.)
In the test report, paragraph 10.3.1. now reads “Hot cycle CO2 (g/kWh)”. Paragraph 10.3.4. now reads “Cycle CO2 for hot start test (g)”, with the unit g instead of g/kWh. Before this supplement, both paragraphs read “Cycle weighted CO2 (g/kWh)”.
Dry-to-wet concentration conversion (Annex 5, Appendix A.1, para. A.1.1.3.)
This supplement amends paragraph A.1.1.3. of Annex 5, Appendix A.1 under its own number. In this paragraph, “are not applicable.” now reads “are not applicable.:”. The RegVault Note about paragraph A.1.1.3. is removed. That note said that ECE/TRANS/WP.29/2024/52 amends “paragraph A.1.1.6.3.” twice, and that its first quoted text is numbered and titled A.1.1.3.
Title of Table A.11.1. for engines operated solely on hydrogen (Annex 11)
