How MaxxForce® Advanced EGR works.
EGR (Exhaust Gas Recirculation) is an emissions reduction technique already 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 hot, oxides of nitrogen (NOx) form. When these nitrous oxides combine with hydrocarbons, they produce the ugly haze we call smog once in the air. 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.
2010 MaxxForce Advanced EGR engines are engineered to precisely control the flow of re-circulated exhaust. These 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.
