Method for confirming deposition of particulate load in particulate filter in exhaust pipe of internal combustion engine, involves considering correction factor when ideal particulate emissions are at discharge mode

摘要

The method involves determining a discharge mode according to operation characteristics of an engine, and measuring actual particulate emissions in air flow and particles using a measurement cell. Ideal particulate emissions are calculated in a measuring area through the exhaust mode. The measured actual particulate emissions are compared to obtain the ideal particulate emissions. A correction factor is determined according to the measured actual particulate. The correction factor is considered when the ideal particulate emissions are at the discharge mode.
