6. The expert from IMMA proposed to introduce the calculated engine speed for various types of transmission into Regulation No. 41 (ECE/TRANS/WP.29/GRB/2015/2 and Corr. 1, Corr. 2). GRB adopted the proposal and mandated the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2015 sessions as a draft Supplement to Regulation No. 41.

Proposal for amendments to the 04 series of amendments to Regulation No. 41
|
|
Reference Number: GRB/2015/2
|
|
Under the current 04 series of amendments to UN Regulation No. 41, the engine speed should be measured during all tests in Annex 3 and Annex 7 (Additional sound emission provisions – ASEP). However, IMMA has found that there is very little difference between the measured and the calculated engine speed for a manual transmission (MT) vehicle (Annex, figure 1) and no impact on the test result (Annex, figure 2). Therefore, this proposal would introduce a calculated engine speed for MT vehicles and for continuously variable transmission (CVT)/automatic transmission (AT) with locked gear mechanism into UN Regulation No. 41.

Proposal to amend R41-04 to formalize the GRB interpretation of the conformity of production

Reference Number: GRB-61-11

|
In response to concerns that approval agencies may not grant manufacturers the additional 1dB for L(wot) on conformity of production tests as changes had been made to Annex 6 of R41-04, GRB issued an interpretation recorded in the report of its 56th session. However, IMMA believes that industry and agency personnel may still not be aware of the interpretation. Therefore, IMMA proposes to codify the interpretation within UN R41.
