Investigation of processes in the WLTC test of a passenger car with a diesel engine

The tests were carried out in accordance with the WLTP (Worldwide Light Duty Test Procedure), on a passenger car compression ignition engine. analysis was conducted doe following variables: vehicle speed, exhaust emission rate and fuel consumption volumetric rate. subject of research are components that harmful to health living organisms: carbon monoxide, hydrocarbons nitrogen oxides, as well greenhouse gases. results have shown very large range values for organic compounds oxides characteristics. average distance-specific emissions small line Euro 6 requirements within margin. Correlation studies measured variables – between speed rates, rates rates. Dimensionless statistical characteristics determined, such as: extreme values, range, mean value, median, standard deviation, kurtosis, skewness coefficient variation. variation made it possible assess most dynamic properties could be observed rate, followed by monoxide finally speed. histogram characterized relative uniformity apart from dominance idle Histograms frequently dominated values.
