In diesel engines in particular, EGR systems come with serious drawbacks, one of which is a reduction in engine longevity. For example, because the EGR system routes exhaust gas directly back into the cylinder intake without any form of filtration, this exhaust gas contains carbon particulates. And, because these tiny particles are abrasive ...
Volvo D5 engine D5244T15 (), in 2015 model year Volvo XC70It is an all-aluminium five-cylinder engine with 20 valves and double overhead camshafts.In all but one late version it has a VGT turbocharger of the type VNT (variable nozzle turbine), common rail direct injection and cooled exhaust gas recirculation (EGR).
The way they do this is during a deceleration of the vehicle when there is low absolute pressure in the intake manifold (i.e., a high vacuum present in the intake manifold relative to the outside air) the powertrain control module (PCM) will open the EGR valve and then monitor the MAP sensor's values. If the EGR is functioning properly, the ...
