Particulate matter emission characteristics for a compression ignition engine fueled with a blend of biodiesel and diesel

摘要

The particulate matter produced by diesel engines, also called PM, are solid particle formations of microscopic dimensions suspended in air. Their extremely small size is one of the problems. Many studies have shown that they can aggravate lung and heart problems and can cause eyes irritation of the human body, if exposed for longer periods of time. Diesel soot particles are toxic air contaminants, which contain toxic heavy metals and dangerous organic pollutants. In this paper, the authors present the particles emission for different blends of bio fuel with diesel under different load and speed conditions. The simulation model was built in AVL BOOST based on the AVL 5402 single cylinder research diesel engine of the Testecocel laboratory, from The Department of Automotive Engineering and Transports, Faculty of Mechanics of Technical University of Cluj-Napoca. The biodiesel fuel used was palm oil methyl ester in different proportions, the purpose of the work was to highlight the particulate matter emission when running with a mix of biodiesel and diesel for different engine speeds. The tests have shown that biodiesel can be used in a blend with pure diesel to reduce the particulate matter.
