Informative Speech on Egr, Dpf, Scr Emission Systems

Preparation Outline Title: Emission Control Advances on Diesel Engines Specific Purpose Statement: To inform my audience about diesel emission technologies. Central Idea Statement: There has been three major technologies added to diesel exhaust systems since 2003 including an EGR, DPF, and SCR that have dramatically reduced NOx emissions (smog gases). Introduction I. Who knows the fundamental difference between a gas and diesel engine? A. A gas engine uses spark to ignite gasoline while a diesel engine uses compressed air to ignite the diesel fuel. II. Diesel engines in turn run more efficiently or simply get better miles per gallon than a similar sized gasoline engine. A. A diesel engine are more efficient up to†¦show more content†¦B. Domestic and foreign automotive manufactures have collaborated on developing these systems and the EPA has invested millions of dollars into the research and development to make diesel engines run clean and efficient. C. So you may still ask, what does this have to do with me, well let me ask, do you breath? Bibliography Blumberg, Katherin O. LOW-SULFUR GASOLINE amp; DIESEL.
