This study presents the proposal for calculations of overall characteristics of unit HC emissions from passenger whicles. Inspiration for the project was derived from the author 's own research and the research works by the selected centres, both in Poland and abroad. Overall, (static) characteristics, with maps of unit emissions of HC, CO and NOx were employed as a basis. This assumption is based on different profiles of fuel consumption and emissions in driving and non-driving phases. In calculations for driving conditions, static overall characteristics of unit emissions were complemented with characteristics of changes in DeltaHC, DeltaCO and DeltaNOx for non-stationary engine working conditions. The author based on the results obtained by other authors has already developed these partial characteristics. Development of reliable characteristics requires implementation of expensive research program (in cooperation with main research centres in Poland), which will require changes in a leading control parameter. In particular, uncorrected, corrected, dynamic correction maps for emissions of HC, examples of dynamic characteristics for emissions from vehicles, characteristics of HC emissions for 5 run-up phases in higher gears and engine braking, numbers for vehicle driving and non-driving phases considered in calculations, coverage of operation field for the engine, static overall characteristics of unit HC emissions, effect of equivalence ratio on performance of three-way catalytic exhaust converter are presented in the paper.
