Proposal to avoid a redundant correction of the measured engine power of supercharged and turbocharged engines fitted with a self-correcting system for ambient conditions such as temperature and altitude. The current correction factor may yield inaccurate results for such configurations.

UN R85 | Revision 1 | Amendment 2 (2019)
16 Jan 2019 2019-01-25 10:34:38 UTC 1 2 00 series of amendments | Supplement 8 Based upon the adopted proposal: WP.29/2018/50

Proposal to clarify the wording of the determination of the net power for electric motors and to correct an error in the formula presented in paragraph 5.4.2. Diesel engines – Factor αd. The parameter “fm” in the equation should be a superscript (e.g., meaning “to the power of fm”). Through a transcription error, this factor was rendered in normal text.

Proposal to reduce testing burdens by introducing an alternative test method to “decrease the charge air cooler outlet temperature by the same amount that the ambient conditions for the vehicle test varied from the standard temperature.” This aligns with SAE J1349, “9.3 Application of Vehicle Transient Data to Net Power Test.”
