An engine shall be remapped prior to a test cycle if:. Other systems or analysers may be approved by the Technical Service if it is found that they yield equivalent results on the respective test cycle. On delivery to the customer the engine shall bear a label see paragraph 5. Since various types of dilution rate control may be used, different calculation methods for G EDFW apply. Ibm Thinkcentre A51p g 2. Optionally, the test may start directly from the engine preconditioning phase without shutting the engine off, when the engine has reached the idle speed.

This Directive is addressed to the Member States. The calculation shall be carried out in accordance with section 4. The application for approval of a vehicle with regard to emission of gaseous and particulate pollutants by its diesel engine or engine family and with regard to the level of the emission of gaseous pollutants by its gas engine or engine family shall be submitted by the vehicle manufacturer or a duly accredited representative. The tailpipe shall be connected to the full flow dilution system.
The same methodology shall be used for integrating both reference and actual engine power. Power absorbed 8422-771g auxiliaries to be fitted for test. The Bessel algorithm shall then be applied to the instantaneous smoke trace k-valueas described in section 6. If a malfunction occurs in any of the required test equipment during the test cycle, the test shall be voided. A different type of recording can be used if it ensures an equivalent data acquisition. With the agreement of 8422-71h authority, all other engines type approved to row A, B1 or B2, or C of the tables in section 6.
The following formulae shall be applied: In that case a fail decision is recorded. The limit values are given in section 6. Installation of the Measuring Equipment. If flow compensation i. Other drivers most commonly associated with Ibm Thinkcentre A51p g problems: Mass of non-methane hydrocarbons.
