The Ultimate Guide To Understanding The Cummins 6 7 Egr Cooler Diagram The cummins 6.7 egr cooler is a component of the exhaust gas recirculation (egr) system in cummins diesel engines. it plays a vital role in reducing nitrogen oxide (nox) emissions and improving overall engine efficiency. the egr system is designed to reduce the formation of harmful pollutants by recirculating a portion of the engine’s exhaust. A cooler (2) reduces the temperature of the exhaust gas before it is combined with the intake air, which increases the ability of the existing volume of inert gas to reduce nox. the egr cooler is cooled by the engine coolant. the egr system contains the following components: egr cooler (2) egr valve assembly (5) egr valve crossover tube (4).
Cummins 6 7 Egr Cooler Detailed Parts Diagram And Functionality The cummins 6.7 egr cooler diagram shows the various components of the egr (exhaust gas recirculation) system in a cummins 6.7 engine. the egr system is designed to reduce emissions by recirculating a portion of the exhaust gases back into the intake manifold, where they are combined with fresh air and fuel for combustion. The dpf system is a honeycomb filter, similar to a traditional catalytic converter, that captures and collects particulate soot. the 6.7 cummins has had a dpf system since halfway through the 2007 model year. 2007.5 2012 models had a completely separate dpf system that sat behind the doc system. in 2013 models the doc and dpf were integrated. 3. actually take a look at the egr valve for any indications of wear or harm. assuming the valve is flawed, it might cause strange voltage readings at the sensor. 4. examine the egr cooler for any indications of stopping up or harm. an obstructed egr cooler 6.7 cummins cooler can make the egr valve breakdown and trigger the issue code. 5. 6.7l cummins engine assembly – egr cooler coolant lines. • for rear gear train engines, if disassembled, assemble the egr cooler supply line onto the egr cooler and install the egr cooler assembly. refer to procedure 011 019. • install and connect the egr cooler coolant supply line to the cylinder head coolant fitting. secure the hose.
