Experimental research on Diesel Particle Filter (DPF) in relation to the fuel type

Abstract

The experimental research is developed to validate or to dismiss theoretical suppositions considering the efficiency of particulate matter filters for internal combustion engines. This paper is pointing out the ideas of a practical test regarding soot impact upon the diesel particle filter from after treatment system, supplied with different fuels in operation mode. Measurements are recorded with after treatment system scanner and subsequently the experimental data are processed and graphically presented using digital module. Experience and know-how concerning the after-treatment system applied to the exhaust pipe of a Diesel engine is extremely useful in modelling the protocol for sustainable technical design of the automotive powertrains. The present paper outlines an applied process of controlling and analysing at least four parameters defining the clogging level of an actual diesel particle filter in K9K792 euro 5 internal combustion engine in relation to the fuel type. Engine supplied with Diesel standard has a wide range of clogging, but when changing to more blended fuels containing biodiesel from soy methyl ester and ethanol, the after treatment process is influenced significantly. The experimental testing is designed to reiterate for each fuel type in real time and after a distance of one thousand kilometres - in engine speed regime of two thousand revolutions per minute.
