ECE R115 PDF

Home Service R Useful Information. The amount of documentation supplied by importers and wholesalers is inconsistent and varies widely. However, it is crucial that the documents are put together correctly so that they do not raise any questions with the retrofitter, the end customer or the Admission Board. After consultation with the technical supervisory associations, we have prepared a brief summary to give you an overview of the scope of documentation for the ECE R system supplied. We have prepared an overview of all vehicles that can be covered by our ECE R homologations so that you can process retrofit enquiries quickly and easily.

Installation manual s for the retrofit system installation on the parent vehicle s. A sample of the specific retrofit system, properly installed in the parent vehicle s. The sample s of a specific retrofit system submitted to type-approval shall be accompanied by a plate with the trade name or mark of the retrofit manufacturer and the type, as indicated in Annexes 2A and 2B.

All retrofit systems, installed in the vehicle belonging to the family, as defined in paragraph 2 of this Regulation, shall be identified by a plate, in which the approval number, and the technical specifications, as required in Annexes 2A and 2B shall be placed. This plate has to be permanently fixed to the structure of the vehicle and shall be clearly readable and indelible. If the retrofit system sample submitted for approval meets the requirements of paragraph 6 of this Regulation, the type-approval of the retrofit system shall be granted.

An approval number shall be assigned to each type of the retrofit system approved. Its first two digits at present 00 according to the Regulation in its original form shall indicate the series of amendments incorporating the most recent major technical amendments made to the Regulation at the time of issue of the approval.

The same Contracting Party shall not assign the same type-approval number to another type of retrofit system. An international approval mark shall be affixed in the plate as indicated in Annexes 2A and 2B, to all retrofit systems, conforming to a type approved under this Regulation, in addition to the mark prescribed in this paragraph 4.

This approval mark shall consist of:. The approval number consists of the retrofit system type-approval number, which appears in the communication form for this type see paragraph 5. Annexes 2A and 2B to this Regulation give examples of the arrangement of the aforesaid plate with approval mark. Requirements for the installation of specific equipment for the use of LPG in the propulsion system of a vehicle. Components indicated in Regulation No 67, 01 series of amendments and defined as necessary;.

The LPG retrofit system may also include components indicated as optional in Regulation No 67, 01 series of amendments. The LPG retrofit system installed in the vehicle, in a proper way as defined in the above installation manual, shall comply with the installation requirements of Regulation No 67, 01 series of amendments. Concerning the fixation of the fuel container, the requirements of Regulation No 67, 01 series of amendments shall be deemed to be met if the requirements of Annex 5 to the present Regulation are satisfied.

Pollutants emissions and CO 2 emissions for categories M 1 and N 1 vehicles only. One LPG retrofit system sample, as described in paragraph 2. Fuel requirements by the engine: the type of fuel normally used by the engine could be:. CH 1,85 for petrol,. CH 1,86 for diesel fuel,. CH 2,52 for LPG,. CH to be defined for dual fuel;.

The LPG retrofit system, as described in paragraph 2. The emissions of CO 2 are calculated according to Regulation No for each parent vehicle, if applicable. The mean of CO 2 emissions shall be calculated as follows:. The mean fuel consumption shall be calculated in the same way as for the mean of CO 2 emissions, as defined in paragraph 6. The ratios of CO 2 emissions and fuel consumption shall be calculated as follows:.

For each vehicle of the family, the official values of CO 2 emissions are multiplied by the above ratios. Exhaust emissions M 2 , M 3 , N 2 and N 3 categories of vehicles. This paragraph is reserved for the specific requirements for emissions of diesel engines approved according to Regulation No 49 and equipped with a retrofit LPG system dual fuel if required. One LPG retrofit system sample as described in paragraph 2. The maximum power at the wheels is measured on a chassis dynamometer on each parent vehicle with the following fuels:.
