Services on Demand Article. There is also an interrelation between FBP, density and sulfur content because of their tendency to concentrate more in heavy fractions, which has made it very difficult to evaluate the individual influence of each on PM emissions. In case of a dual-fuel engine, the engine family shall also comply with the additional requirements of paragraph 3.

Acceptable Exhaust system volume: Exhaust gas recirculation EGR: Number ede OBD engine families within the engine family considered when ensuring the correct operation of NO x control measures.

By fuel injection positive ignition only: The manufacturer shall ensure that the emissions test results comply with the applicable limit value under the test conditions specified in this Regulation. Technical requirements for diesel-gas dual-fuel engines and vehicles.

If the crankcase is of an open type, the emissions shall be measured and added to the tailpipe emissions, following the provisions set out in paragraph 6. Make and type of pressure regulator. Choice of the parent engine The parent engine of the family shall f49 selected in accordance with the requirements set out in paragraph 5. Additionally, the results of the tests shall be reported to that Contracting Party and the approval authorities.

If the Type Approval Authority which granted the original type approval establishes that no agreement can be reached, it shall take the necessary measures, including, where necessary, the withdrawal of type approval, to ensure that production vehicles, systems, components or separate technical units, as the case may be, are brought into conformity with the approved type.

The tests may be carried out on engines that have been run-in, up to a maximum of hours.
