Research on the impact of vehicle aging on the amount of air pollution emissions

This article addresses the issue of aging passenger vehicles and their impact on air pollutant emissions. The problem of vehicle aging and the related change in air pollutant emissions was analyzed based on the operational mileage of passenger vehicles. The research method included measuring the actual emission of RDE air pollutants using research equipment, i.e., the SEMTECH DS exhaust gas component analyzer. The tests were conducted on vehicles with compression-ignition engines of different operating ages, different mileage, and similar displacement engines (1.9 dm3 - 2.0 dm3) equipped with a manual gearbox.
