Abstract

The paper presents the results of on-road (city traffic) exhaust emission and fuel consumption tests related to a vehicle fitted with a start-stop system. The tests of different types of vehicle cruise cycles were performed on road portions of several kilometers under different traffic conditions. For the tests a portable exhaust analyzer SEMTECH DS was used. It measured the concentrations of the exhaust components and the exhaust gas mass flow. As a result the authors determined the usefulness of the engine disengaging systems in vehicles under the conditions of city traffic.
