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 is a layer of Earth's atmosphere above the mesosphere. The thermosphere extends from 50 to 55 miles (80-90 km) above sea level, with the upper limit undefined â¦ . The temperature in the thermosphere initially rises rapidly with heights up to about 120 miles (200 km) and thereafter increases more slowly. The definition of thermosphere is the atmosphere layer between the mesophere and the exosphere The thermoshpere is the biggest of all the layers of the Earth's atmospher â¦ edirecly above the mesosphere and directly below the exoshpere. 2 people found this useful.
