Calculations of exhaust emissions produced by vehicle with petrol engine in urban area

Abstract

Abstract The paper deals with the method of calculating exhaust emissions of a passenger vehicle during drive in urban area. For this calculation, a running test was conducted in which exhaust gas volume data and engine control data were recorded. The evaluated exhaust gas components are nitrogen oxide, hydrocarbon, carbon monoxide, carbon dioxide. The engine speed, intake air quantity, vehicle speed and intake air temperature were recorded from the engine control unit. The exhaust components are calculated in gram per kilometre of vehicle drive.
