In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO x) emissions reduction technique used in petrol/gasoline and diesel works by recirculating a portion of an engine's exhaust gas back to the engine dilutes the O 2 in the incoming air stream and provides gases inert to combustion to act as absorbents of combustion heat to reduce ...

the catalyst aging bench burner without secondary exhaust gas recirculation is close to the minimum exhaust gas flow borderline (fig. 4). The minimum flow is required to cool the burner walls. By recirculating exhaust gas after passing it through the catalyst, a wide operation map of mass flow and temperature can be realized.

This sensor allows temperature measurement in EGR systems, EGR bypass valve function diagnostic as well as thermal protection.
A catalytic converter is an exhaust emission control device that converts toxic gases and pollutants in exhaust gas from an internal combustion engine into lesstoxic pollutants by catalyzing a redox reaction (an oxidation and a reduction reaction). Catalytic converters are usually used with internal combustion engines fueled by either gasoline or diesel—including leanburn engines as well ...

Aug 03, 2013· Understanding exhaust gas recirculation systems By: Henry Guzman Exhaust gas recirculation (EGR) systems were introduced in the early '70s to reduce an exhaust emission that was not being cleaned by the other smog controls. Oxides of nitrogen (NOx) are formed when temperatures in the combustion chamber get too hot.
oxidation catalyst and new exhaust purification systems such as the SCR catalyst and NOx storage catalyst. One of the techniques available for use inside the engine for reducing NOx emissions is cooled exhaust gas recirculation. Together with turbocharging with cooled charge air, this is an effective technology for the reduction of emissions.
Exhaust Gas Recirculation Filter This product is a lifetime EGRfilter with highest efficiency to protect turbocharger from ceramic particles due to DPF regeneration.
