Requirements on universal fuel range type approval A universal fuel range approval shall be granted subject to the requirements specified in paragraphs 4. In case of an application for approval for a vehicle type with an approved engine, the marking specified in paragraph 4.

The evolution coefficient of the emissions between the two tests shall be calculated for each pollutant:. The effects of density and sulfur content are less important. Other parameters of fuel quality that influence PM emissions or black smoke are cetane number, density and aromatic content, which is not normally specified. At the request of the Type Approval Authority, the manufacturer shall demonstrate the availability or the conformity of the ECU information in serial production by performing the appropriate testing referred to in paragraphs 8.

Where the Type Approval Authority which granted the original type approval is not satisfied with the results of in-service tests or confirmatory tests in accordance with the criteria set out in Annex 8, or based on in-service testing conducted by a Contracting Party, it shall require the manufacturer to submit a plan of remedial measures to remedy the non-conformity in accordance with paragraph 9.

Description of the system in the case of systems other than continuous injection give equivalent details. The requirements of paragraph 6.

This implies tests as described paragraph 4. Type ee of vehicle with an approved engine with regard to emission. Description of the system. Need more search options?

It shall contain the test results according to paragraph 10 of Annex 8. The production is deemed to conform if at least three engines out of the further random sample of four engines meet the requirements of the tests described in Annex 9B.

The parent engine of the family shall be selected in accordance with the requirements set out in paragraph 5.

This factor should be considered in the reformulation and specification of diesel characteristics. Name and address of manufacturer. Test cycle used for the verification of the OBD system 7.

A universal fuel range approval shall be granted subject to the requirements specified in paragraphs 4. Due to the impulse in the use of diesel engines on mass transport vehicles during the last year in different cities in Colombia, it is necessary to seek the best options to reduce emissions to a rce.

THE EFFECT OF DIESEL PROPERTIES ON THE EMISSIONS OF PARTICULATE MATTER

Make trade name of manufacturer. The extended documentation package shall remain strictly confidential. This appendix describes the procedure to be used to verify, at the manufacturer’s request, production conformity for the emissions of pollutants. Diesel with a sulfur content of ppm was obtained by using a commercial diesel ppm sulfur through hydrotreatment in the pilot plant. The tests were performed at the Instituto Colombiano del Petroleo.

It shall be made open for inspection by the D49 Approval Authority at the time of approval or at any time during the validity of the approval. The results obtained are evaluated for each and every engine and this determines the general trends in the reduction of PM emissions from modifying the properties of the commercial diesel fuel.

In the case where the manufacturer can demonstrate to the satisfaction of the Type Approval Authority that further time is required to perform additional testing, an extension may be granted. Emission limits Table 1 provides the emissions limits that apply to this Regulation.

Ecd case of an application for approval for a vehicle type in respect of its engine, the marking specified in paragraph 4.

Work window conformity factor. The values of the pollutants given in paragraph 5. Diesel from the U. The subsequent test engines shall not be subjected to the running-in procedure, but their emissions when newly manufactured shall be modified by the evolution coefficient. It is referring to measures to be taken against the emission of gaseous and particulate pollutants from engine systems and vehicles.

Nevertheless, the introduction of low sulfur diesel fuels in some parts of the world has coincided with an increase in the report of faulty pumps due to excessive levels of wear from friction. The manufacturer shall ensure that replacement pollution control devices intended to be fitted to type-approved engine systems or vehicles covered by this Regulation are type-approved, as separate technical units in accordance with the requirements of paragraphs 4.
