Diesel Exhaust Fluid (DEF) consumption is measured as a ratio of diesel fuel use, normally termed the dosing rate or treat rate. Medium-and heavy-duty vehicles have a dosing rate of 2-3%.EF is sprayed into the exhaust stream of diesel vehicles to break down dangerous NOx emissions into harmless nitrogen and water. This system is called Selective Catalytic Reduction (SCR) and can be found on 2010 and later model year trucks and many diesel pickups and SUVs.
The layer of the atmosphere where weather occurs is the Thermosphere (True) The Mesosphere is the layer of the atmosphere that contains ozone (False) The exosphere is the outer layer of the thermosphere (I don't know sorry :) Most meteoroids burn up in the stratosphere (True) The tropophere is divided into the inospere and the exosphere (don't know)
The thermosphere has extremely high temperatures, coinciding with the prefix in its name, thermo, which means temperature. Temperatures can reach over 3,600 degrees Fahrenheit, and the high heat comes from the intense light rays, or radiation, from the sun. Since there is little to no atmospheric gases above the thermosphere, there is no absorption of the heat from solar radiation, and so temperatures soar. In lower layers of the atmosphere, as you increase in altitude, temperature decreases The thermosphere is the first layer to which this pattern does not apply. Ã
