The article presents the results of research on harmful compound emissions from an engine and fuel consumption of a vehicle equipped with a Start/Stop system in real urban traffic conditions. Tests for various types of trips were carried out on sections of several dozen kilometers in different road conditions. A mobile analyzer for toxicity testing, SEMTECH DS by SENSORS, was used to measure the concentration of toxic compounds. The analyzer enabled the measurement of harmful compound concentrations while simultaneously measuring the mass flow rate of exhaust gases. As a result of the obtained findings, the sense of using engine-shutting systems in urban traffic conditions was determined.REAL TRAFFIC EXHAUST EMISSIONS FROM VEHICLES
FITTED WITH A START/STOP SYSTEM
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. (…)
