Conditions in an egr environment test fixture o cummins ism engine with variable geometry turbocharger production egr cooler and electronically controlled egr valve test parameters o the engine is operated for 200 hours using 500 ppm sulfur fuel test parts evaluation o injector adjusting screw o crosshead o top ring wear. The next generation came out with the cummins isx and had pretty much the same problems as the cummins ism did egr issues were common problems on these engines you would get a warning light on the dash and a code stored in the ecm most of the time the problem with the egr valve was that the egr valve would not open and close all the way.
