Draft calculation of fuel consumption and emission of CO, HC and NOX by a engine car in operational conditions

The study presents a draft calculation of fuel consumption and emission of CO2, CO, HC and NOx by a engine car used in real traffic conditions. In this project, the author was inspired by the results of his own studies and those of selected domestic and foreign research centres. The (static) engine performance maps including Brake Specific Fuel Consumption maps, ge (CO2), and maps of speciftc emission of CO, HC and NOX,, serve as the basis for this study. Underlying such an approach are the disparate courses offuel consumption and emission levels in the driving and non-driving modes of the engine. For the study purposes, an adeąuate testing programme should be implemented, using a variable driving cycle [1]. A departure from the homologation cycles applied to this end allows covering, on an engine performance map, the area of engine operation being of interest to us with measuring points. For calculations in operational conditions, the maps of changes of Delta ge, Delta CO2, Delta CO, Delta HC and Delta NOX for nonstationary operating conditions of the engine will be a complement to static engine performance maps. The author has already developed partial maps for the first two parameters. The development of the others requires the implementation of a costly research scheme in cooperation with a leading domestic research centre.
