EGR | International

EGR (Exhaust Gas Recirculation) is an emissions reduction technique used in most gasoline and diesel engines. EGR works by re-circulating a portion of an engine’s exhaust back to the engine cylinders and burning off excess pollutants. When temperatures in the combustion chamber get too hot, oxides of nitrogen (NOx) form. When these nitrous oxides combine with hydrocarbons, they produce the ugly haze we call smog. EGR re-circulates this exhaust into the intake stream. Since the exhaust gases have already combusted, they don’t burn again. These gases displace some of the normal intake, slowing and cooling the combustion process, which reduces NOx formation.

The challenge for 2010 is to precisely control the flow of re-circulated exhaust. MaxxForce advanced EGR engines have increased injection pressure, improved combustion and refined calibrations with that goal in mind. The result is an engine that treats NOx in-cylinder, and therefore requires no extra effort from our customers.

  • Step One : Cleaning and Heating – The first step in cleaning the diesel exhaust occurs when the exhaust stream enters the Diesel Oxidation Catalyst (DOC). The role of the DOC is twofold. First, it converts and oxidizes hydrocarbons into water and carbon dioxide. This conversion happens at about 250 degrees Celsius.

  • Step Two : Knocking Out the NOx – The next step in the process is what's known as Selective Catalytic Reduction (SCR). In this process, the NOx in the exhaust stream is converted into water and inert nitrogen, which is present in the atmosphere and harmless. Before the exhaust gas enters the SCR chamber, it is dosed with DEF, an aqueous solution that is approximately 67.5 percent water and 32.5 percent pure urea.

  • Step Three : Scrubbing Away the Soot – The final part of the cleansing system for the diesel exhaust gas involves the Diesel Particulate Filter (DPF). The DPF traps any remaining soot, which is then periodically burned away, known as regenerating, when sensors detect the trap is full. The regeneration process sees temperatures in excess of 600 degrees Celsius to burn away soot.

    "Having this diesel designed in-house at Ford meant we were able to work on optimizations and refinements right from the start," said Tim Ogilvie, vehicle energy supervisor. "We're able to deliver to customers a more refined, more fuel-efficient Super Duty, with class-leading torque and horsepower and the class-leading capability they demand."
