Revised proposal, superseding document GRPE/2018/5, 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.

The expert from OICA presented ECE/TRANS/WP.29/GRPE/2018/5 as amended by GRPE-76-23 proposing a solution for the concern raised by the expert from UK in GRPE-75-13 and corrects a long standing error in a formula shown by OICA in GRPE-75-12.
