Research of Diesel Particle Filter Soot Impact and Regeneration Time Trend-Line

Abstract

The experimental research paper takes into consideration the possibility of experimental testing and tracking the trend line of the particulate soot impact, particulate filter differential pressure, exhaust gas temperature upstream of particulate filter of using Diesel Standard fuel with compression ignited engines, as well as the influence that each temperature value and the time instances have upon the particle filter regeneration, on the trend line in the testing time. For the practical application i was supplied Diesel Standard fuel and its blends in accordance with operating regime. Specific experimental setting was developed and actual values were collected with accurate digital systems. Practical tests and data collection were realized in order to obtain the significant trend line in the given time of the test in parallel with temperature and pressure. By measuring the latter parameters and voltage on the exhaust gas differential pressure some trend line equations may be traced which sustain the regression squared values for a more complex analyze of the phenomena. The most significant soot impact was reached after thirty minutes of regeneration procedure. Engine speed was above 2000 rpm and coolant’s temperature higher than 80 ℃.
