EXHAUST EMISSIONS AND FUEL CONSUMPTION FOR ELEVEN CARS OF THE SAME MODEL. INTER AND INTRA VARIATIONS IN MEASURED DATA
AVGASEMISSIONER OCH BRAENSLEFOERBRUKNING FOER ELVA PERSONBILAR AV SAMMA TYP. INOM- OCH MELLANVARIATIONER
Measurements of engine speed, effect, torque, fuel consumption, and emissions of carbon dioxide, nitrogen monoxide, hydrocarbons and carbon monoxide at various engine work points defined by effect/engine speed, were made for eleven VW polo cars of year model 1988. An APG-dynamometer (Automatic Performance Guide) was used in the experiments. One of the vehicles was tested twice on different occasions. Confidence intervals for single vehicles were calculated on the assumption that the measured values are presumed to be mutually independent and equally distributed. Large differences, between different vehicles, in emissions of NO and HC were registered. The emissions of CO also exhibit considerable variability, while the results for fuel consumption, and consequently for emissions of CO2 were much more uniform. (A)
