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.

The latest legislation regarding the reduction of harmful exhaust emissions, greenhouse gases and fuel consumption determines not only maximum permissible emissions factors, but also emissions testing methods and laboratory design and additionally leads to the development of new research methods. BOSMAL has risen to meet these challenges by investing in an updated, state-of-the-art emissions testing laboratory, housed within a climate chamber and in parallel investing in a completely new laboratory designed with incoming and future legislative requirements in mind. This paper presents BOSMAL’s improved M1/N1 vehicular emissions and fuel consumption laboratory in a climatic chamber and BOSMAL’s standard chamber for the testing of vehicles in accordance with European Union, US and Japanese standards. The specifications, capabilities and design features of the sampling, analysis and development research possibilities and climate simulation systems are presented and discussed in relation to the increasing drive for cleaner, light duty road vehicles (including hybrids and electric vehicles). The recently-renovated laboratory with extended standard temperature range and the laboratory with climatic chamber are described in the context of the newest European Union legislation on the emission in the range of Euro 6d testing requirements. The laboratories permit BOSMAL’s engineers to compete in the international automotive arena in the development of new, more ecologically friendly and increasingly fuel efficient vehicles.

W artykule przedstawiono analizę emisji tlenku węgla i azotów z kotła wodnego małej mocy opalanego różnymi paliwami węglowymi. Kocioł, przedstawiony do badań spełniał warunki emisji dla kotłów wykonanych w klasie piątej zgodnie z normą PN-EN 303-5:2012. Obiekt badawczy miał palnik z automatycznym podawaniem paliwa, sterowany za pomocą mikroprocesorowego regulatora temperatury. Celem badań było sprawdzenie czy kocioł spełni najwyższą klasę ekologiczności bez względu na jakość i parametry techniczne zastosowanego paliwa. W artykule opisano metodologię badań oraz analizę otrzymanych wyników. Efektem przeprowadzonych badań jest zestawienie średnich wartości emisji tlenku węgla oraz tlenków azotu w zależności od zastosowanego paliwa. Wyniki badań stanowią przesłankę do dalszej pracy badawczej pod kątem wpływu zastosowanego paliwa na emisję substancji szkodliwych.

The article presents an analysis of the emission of carbon monoxide and nitrogen oxides from a low power boiler fired with various coal fuels. The boiler, presented for testing, met the emission conditions for boilers made in the fifth class in accordance with the PN-EN 303-5: 2012 standard. The research object had a burner with automatic fuel supply controlled by a microprocessor temperature controller. The purpose of the tests was to check whether the boiler fulfills its highest environmental class regardless of the quality and technical parameters of the fuel used. The article describes the research methodology and analysis of the results obtained. The effect of the tests carried out is a comparison of average values of carbon monoxide and nitrogen oxides emissions depending on the fuel used. The results of the tests constitute a premise for further research work in terms of the impact of the used fuel on the emission of harmful substances.
