Analysis of exhaust emission measurements in rural conditions from heavy-duty vehicle

Abstract

Road transport holds for the largest share in the freight transport sector in Europe. This work is carried out by heavy vehicles of various types. It is assumed that, in principle, transport should take place on the main road connections, such as motorways or national roads. Their share in the polish road infrastructure is not dominant. Rural and communal roads roads are the most prevalent. This fact formed the basis of the exhaust emissions and fuel consumption tests of heavy vehicles in real operating conditions. A set of vehicles (truck tractor with a semi-trailer) meeting the Euro V emission norm, transporting a load of 24,800 kg, was selected for the tests. The research was carried out on an non-urban route, the test route length was 22 km. A mobile Semtech DS instrument was used, which was used to measure the exhaust emissions. Based on the obtained results, the emission characteristics were determined in relation to the operating parameters of the vehicles drive system. Road emission, specific emission and fuel consumption values were also calculated.

Analysis of Emissions and Fuel Consumption in Freight Transport

“…41 dm 3 /100 km [44]. In the test presented in Ziółkowski et al [31], the fuel mileage of the investigated vehicle (the same vehicle was used for the investigations of the transport cycle described in this paper) was 30.9 dm 3 /100 km.…”

“…The investigations have shown that the driving technique has a significant impact on the emission of carbon dioxide, hence the energy consumption. The emission of individual exhaust components and the fuel consumption in a test run of a heavy-duty vehicle under actual operating conditions on roads of different classification have become an increasingly frequent subject of scientific research [29][30][31]. The application of the PEMS equipment allows a detailed assessment of the environmental performance of vehicles and machinery under almost any actual operating conditions.…”

Numerical optimization of the BAT-CELL Bio-Ambient-Tests method for engine exhausts toxicity evaluation

“…Research on exhaust emission measurement methods in the context of changing Euro emission standards is an extremely important and topical issue. Commonly used exhaust emission measurement methods can be divided into those using exhaust gas analysers [33] (including portable emissions measurement system PEMS), analytical methods (e.g. chromatography, spectroscopy) and less popular calculation methods [28].…”

The concept of a maintenance-free drive-thru inspection station for commercial vehicles

“…At the present stage of the development of the road transport means, all kinds of activities relating to their impact on the environment play an extremely important role [3]. In this area, a number of legal regulations have been established regarding the conditions of admitting vehicles to roads and a number of control regulations that determine the day-to-day operation of vehicles [4,10]. However, due to the very diversified car fleet and very different conditions of vehicle operation, the existing control regulations do not always effectively and quickly identify vehicles that are operated with faults that endanger their safe operation or exceed the established emission limits.…”
