Traduction de «Pollution par les gaz d'échappement » (Français → Anglais) :

In this context it is worth mentioning the advances in navigation technologies, logistical telecommunications and exploitation, the commitment to reduce pollution and greenhouse gases, securing new investment and the need to bring training up to date for the staff that manage and deal with these aspects.

2.2.1. Determination of the Diluted Exhaust Gas Flow PDP-CVS system The calculation of the mass flow over the cycle, if the temperature of the diluted exhaust is kept within ± 6 K over the cycle by using a heat exchanger, is as follows: M TOTW = 1,293 x V0 x NP x (pB - p1 ) x273 / (101,3 x T) where M TOTW = mass of the diluted exhaust gas on wet basis over the cycle V0 = volume of gas pumped per revolution under test conditions (m³/rev) NP = total revolutions of pump per test pB = atmospheric pressure in the test cell (kPa) p1 = pressure drop below atmospheric at the pump inlet (kPa) T = average temperature of the diluted exhaust gas at ...[+++]pump inlet over the cycle (K) If a system with flow compensation is used (i.e. without heat exchanger), the instantaneous mass emissions shall be calculated and integrated over the cycle.
