Session 76 | Geneva | 9-12 Jan 2018
4. (a) Heavy duty vehicles: Regulations Nos. 49 and 132
GRPE/2018/9 | Proposal for a new Supplement to the 05 series of amendments to Regulation No. 49 Proposal to improve the "random check requirement" and define the rounding of test results calculated according to Annex 4A in the 05 series of amendments.
GRPE/2018/10 | Proposals for a new Supplement to the 06 series of amendments to Regulation No. 49 Proposal to improve the Engine Control Unit (ECU) torque signal validation requirement in the 06 series of amendments to R49 with regard to dual-fuel or flex-fuel vehicles. Under the regulation, the ECU torque information can be calibrated only to one fuel's heat value (usually the basic reference fuel) even though the heat value of the alternative fuel is different. In order to increase the accuracy of the torque values used for calculating the emission results during in-service conformity testing, OICA proposes to change the provisions to either:<ol class="alpha"><li>Demonstrate that both fuels comply because the ODB system is able to detect the fuel used, or</li><li>Determine the torque deviation caused by the alternative fuel heat value compared to the standard fuel and apply this correction factor to calculate a more accurate power signal for the emission calculation.</li></ol>
GRPE-76-08 | Manipulation on EURO IV, EURO V and EURO VI Trucks by Suppression of AdBlue Injection - Situation End of December 2017
GRPE-76-16 | UN R49: Proposals for amendments to document GRPE/2018/10 EC proposals regarding the OICA proposal on the UN R49.06 ECU torque signal validation requirement and dual-fuel or flex-fuel vehicles.
GRPE-76-13 | UN R132: Proposal for Supplement 1 to the 01 series of amendments Proposal to align UN R132 with the proposed 05 series of amendments to Regulation No. 96.
