Abstract:
This paper presents the results of a developed experimental method for misfire identification in engine cylinders. The subject of investigation was a ten-cylinder OM403 engine, licensed by the company "Mercedes-Benz", which is used as a drive unit for specialized tracked vehicles. The methods was developed under laboratory conditions and is based on monitoring pressure and mean temperature pulsations of exhaust gases for different operating conditions in the cylinders at steady state operation while monitoring the in-cylinder pressure of one engine cylinder. The in-cylinder pressure and pressure pulsations in the exhaust manifolds were measured by AVL piezo electric pressure transducers, a data acquisition module (USB 6210 National Instrument), an AVL charge amplifier and the Lab View software for synchronization and management of the measuring equipment. The aim of this paper is to give a practical contribution to studies identifying disturbances of engine working cycles by monitoring parameters of exhaust gases.
