The article presents the results of road tests of the passenger car. The aim of this study was to determine the effect of variations in the vehicle braking methods on the carbon dioxide emissions. Inhibited using the gear ratios increase – less gear and using motion resistance while driving a rundown, in addition to using the brake system in the final stages of journeys made. The use of engine braking by drivers as a result of the reduction gear, for example during transport to the intersection, traffic light, railroad crossing, in place of the drive by coasting is particularly emphasized by the promoters of eco-driving. It is raised the issue of avoiding unproductive, from the viewpoint of the work efficiency of the engine, the engine idle speed. The verification of environmental aspects of the use of engine braking was made because of the testing under real traffic conditions. Test drives were carried out at the measuring section, free from traffic. The test vehicle accelerates to a speed of 50 km/h, and then two ways of the speed deceleration were used. The values of the concentration of harmful carbon dioxide in the exhaust gases were achieved by using a mobile apparatus for testing exhaust emissions.
