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)
Technically the thermosphere is the layer between the mesopshere and the exosphere. the exosphere is the highest layer in the 5 layers of atmosphere. The exosphere temperature â¦ ranges are between 300 degrees to 1700 degrees Celsius, and also it contains hydrogen and helium.Now, facts about the mesosphere.it's the layer within the Earth's atmosphere that extends from about 50 to 85 km (31 to 53 mi) above the surface. The mesosphere is predominantly characterized by its thermal structure. On average, mesospheric temperature decreases with increasing height. Stratosphere: The Layer of the Atmosphere That Shields Against Ultraviolet Rays The stratosphere is a layer of the atmosphere that is often little understood outside scientific circles, though it has entered common usage through the adjective stratospheâ¦.
