Catalyst Sample Test Rig for Biodiesel Fueled Engine Tests

Abstract

U of M is spearheading research in Low Temperature Combustion (LTC)/Premixed Compression Ignition (PCI), a form of diesel combustion that achieves high fuel efficiency with decreased NOx and soot emission but increased hydrocarbon and carbon monoxide emissions. A Diesel Oxidation Catalyst (DOC) is therefore required. This project involves adding a test rig to the current single cylinder engine to allow researchers to quickly test catalyst bricks suitable for LTC/PCI. The rig should be capable of controlling the exhaust gas temperature entering the catalyst so as to simulate the temperature profile from a multi-cylinder engine for useful results. This rig will be vital for future testing involving biofuels.
