New Test Programme DPF canned for easy connection to engine Load on engine or DPG. Cold flow test at 0g, 5g, 15g, 20g & 30g on DPG– Improved accuracy compared with engine backpressure measurementdue to accurate & stable temperature and flow Original plan:regenwarmup0gweighflow testload5gweighflow testload15gweighflow testload20gweighflow testload30gweighflow test10Engine / DPGDPG
Engine Details 2l Common rail Diesel engine Stage 4 emissions compliant Mounted on dynamic dyno– Comparisons made with cycle soot Fitted with Diesel Oxidation Catalyst upstream of DPF– In this test programme, the DPG testing was not fitted with the DOC. This is tosimulate best the application of the DPG for testing filters which are then usedwith an upstream DOC, currently the majority application.– For single brick systems, the engine soot would differ mainly via higher levels ofvolatile components. All tests performed on the same DPF:– 5.66” dia x 10” 4.1 l– Uncatalysed SiC.11
