Abstract
The results of measurements of exhaust emissions in real road traffic differ significantly from the results of stationary homologation tests. One of the solutions, helpful in determining the actual emission, is the creation of stationary exhaust emission tests simulating the use of the vehicle on the road. The article presents the method of reconstructing the synthetic driving test obtained on the basis of road tests and presents the obtained profile of the speed course. The authors discussed the reasonableness of selecting the emission component determining the correctness of the representativity of the stationary test obtained, which determines the amount of work done by the engine.
Highlights
Research on the ecological properties of automotive combustion engines is carried out at almost every stage of the life cycle of vehicles
In order to verify the correctness of the assumptions and the correctness of the construction of the based on road measurements stationary test itself, it was necessary to compare the emission values of individual exhaust components
In the case of hydrocarbons measurement, in road tests the analyzer operating on the principle of using infrared IR built into the mobile measuring device was used, relatively inaccurate in the case of carbon particle emission measurement, due to the registration of the flow of only part of hydrocarbon compounds
Summary
Research on the ecological properties of automotive combustion engines is carried out at almost every stage of the life cycle of vehicles. The results of measurements of exhaust emissions in real road traffic differ significantly from the results of stationary homologation tests.
