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)
(3) In the mesosphere, the air is relatively mixed together, so the temperature decreases with altitude. The atmosphere reaches its coldest temperature of around -90Â°C in the mesosphere. This is also the layer in which a lot of meteors burn up while entering the Earth's atmosphere.(4) The thermosphere is the fourth layer of the Earth's atmosphere.The air is really thin in the thermosphere.A small change in energy can cause a large change in temperature. That's why the temperature is very sensitive to solar activity.4) The thermosphere is the fourth layer of the Earth's atmosphere. The air is really thin in the thermosphere.
