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 lies between the exosphere and the mesosphere. âThermoâ means heat, and the temperature in this layer can reach up to 4,500 degrees Fahrenheit. If you were to hang out in the thermosphere, though, you would be very cold because there arenât enough gas molecules to transfer the heat to you. This also means there arenât enough molecules for sound waves to travel through. This layer of Earthâs atmosphere is about 319 miles (513 kilometers) thick. Thatâs much thicker than the inner layers of the atmosphere, but not nearly as thick as the exosphere. The thermosphere is home to the International Space Station as it orbits Earth. This is also where youâll find low Earth orbit satellites.
