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)

Best Answer: The thermosphere has a high temperature, because the smalll amount of oxygen present is heated up rapidly by solar radiation, causing the molecules to move about rapidly (temperature is the measure of the average kinetic energy of the molecules).emperatures climb sharply in the lower thermosphere (below 200 to 300 km altitude), then level off and hold fairly steady with increasing altitude above that height.
