LOADING CYCLE OF DIESEL DRIVEN VEHICLES UNDER GROUND TO GET CLEANER EXHAUSTS

BELASTNINGSCYKEL HOS DIESEDRIVNA FORDON UNDER JORD FOER RENARE AVGASER

This report (the fourth partial report) concludes a project, that has been accomplished to facilitate manufacture/choice of cleaner diesel engines for underground use. This was found possible by determining the exhaust emissions during a realistic mine-related loading cycle and specifying desirable levels of emission. An important thing was that the loading cycle also was containing dynamic loading moments, so called transients. The project has involved the following: surveying different types of vehicles under ground, mapping of the use of mechanical loaders in Swedish underground mines, registration of the loading cycle on mechanical loaders in current environment, simulation of the conceived loading cycle in a motor laboratory, exhaust measurements in motor laboratory under the current loading cycle. During the project, a new methodology has been developed to: register the motor loading on vehicles during driving, simulate realistic loading cycles with streaks of fast transients and perform continuous analysis of exhausts with satisfactory reproducibility. The project has shown/resulted in the following: a specification of all diesel vehicles in Swedish underground mines, that mechanical loaders and transport vehicles are responsible for 80 per cent of the exhausts under ground, a specification of the cycle times for mining loaders at different kinds of mining methods, that the difference between the motor loading on contractor's machinery and specially made mining loaders is considerable, that drivers' different way of driving are less affecting on the motor loading than differences in machine constructions/road conditions.
