Vehicle interior air quality standards development

Abstract

Abstract The paper presents results of experiments carried out to refine the procedure for determining the content of harmful substances in the air of vehicle interior coming from the supply system and exhaust system of the vehicle under test, as specified in GOST 33554-2015. Based on the work results proposals were prepared for the working group “Vehicle interior air quality”, operating under the auspices of the World Forum for Harmonization of Vehicle Regulations (WP.29) of the United Nations Economic Commission for Europe. Content determination of the air pollutants in the vehicle compartment was carried out under various engine and ventilation system operating conditions when driving along the routes on the testing ground of FSUE “NAMI” and parking in specially selected places with the complete absence of other vehicles in the test area. Based on the test results, a conclusion was made that it is necessary to use a wider range of speed modes and variations in the operation modes of the ventilation system.
