Determining if Exhaust Emission From Light Duty Vehicle During Acceleration on the Basis of On-Road Measurements and Simulations

Vehicle exhaust emissions depend on multiple factors, such as the emission norm, driving parameters (speed, acceleration) or the technical condition of the vehicle. These driving parameters may often depend on the condition of the road infrastructure and other factors influencing road conditions. The article attempts to assess the emissivity during acceleration of a vehicle powered by a compression ignition engine. Mapping the actual values is possible with the use of exhaust emission measurement equipment that operate in the vehicle’s real operating conditions. Recently, an increase in the use of simulation methods in research of this type has been observed. The authors decided to check the suitability of using road traffic simulation software to estimate the CO2 emissions during vehicle acceleration. The obtained results are promising, because in terms of emissions of the analyzed exhaust gas component, the simulation results differed from the results obtained during measurements with the use of PEMS (Portable Emissions Measurement System) equipment by less than ±20%
