Opis:
Biofuels represent one of the alternatives to obtain the CO2 - neutral propulsion of IC-engines. Butanol, which can be produced from biomass, is considered and was investigated in the last years due to the very advantageous characteristics of this alternative fuel. Butanol can be easily and irreversibly blended both with light (gasoline) and heavier (diesel) fuels. Comparing with ethanol it has the advantages of: higher calorific value, lower hygroscopicity and lower corrosivity. It can replace the aviation fuels. This paper presents the emission results obtained on two diesel passenger cars with different technology (Euro 2 and Euro 6c) and with addition of butanol to diesel fuel, as a part of the research project DiBut (diesel and butanol). Interesting results are given about some non-legislated (non-regulated) components, acetaldehyde (MeCHO) and formaldehyde (HCHO) and about the PN-emissions with/without DPF.

Opis:
Testing of real driving emissions (RDE) offers the opportunity to collect the data about the emissions in special driving, or non-driving situations. These situations are: cold start, warm-up of the engine, stop & go and idling. In the present work, the definitions of the special driving situations were proposed, the emissions of 7 passenger cars (gasoline & Diesel) were extracted from the present RDE data and some special driving situations, particularly the stop & go operation with varying share of idling were reproduced on chassis dynamometer. As expected, the emissions of CO, NOx and PN are in the cold start and in the first part of the warm-up phase (ca. 25 s) considerably higher than in the rest of the investigated urban phase. The singular emitting situations like “stop&go” or idling occur frequently in the warm-up phase, i.e. in the city operation when the engine and the exhaust system are still not warm enough.

Opis:
Increasing the sustainability of individual transportation and replacing a part of fossil energy in traffic by renewable energy carriers are worldwide important objectives. Bioalcohols are generally recognized as one of very useful alternatives. The global share of bioethanol used for transportation is continuously increasing. Butanol, a four-carbon alcohol, is considered in the last years as an interesting alternative fuel, both for diesel and for gasoline application. Its advantages for engine operation are: good miscibility with gasoline and diesel fuels, higher calorific value than ethanol, lower hygroscopicity, lower corrosivity and possibility of replacing aviation fuels. In the present work, the emissions of two gasoline vehicles – with older and with newer technology – were investigated in dynamic-, stationary and cold start operation.

Opis:
The implementation of the 3rd package of the RDE test procedure has extended the test method by considering emissions from a cold start period into the total exhaust emissions from a vehicle. The article presents the research results of exhaust emissions of a vehicle equipped with a gasoline engine. The tests were carried out at two different ambient temperatures, in line with the requirements of the RDE test procedure for passenger cars, meeting the Euro 6d-Temp emissions standard. The obtained results were analyzed, i.e. there were compared the engine and vehicle operating parameters and the values of road exhaust emissions during the cold start at two different ambient temperatures. The summary presents the shares of the cold start phase for each exhaust emission compound in the urban part of the test and the entire RDE test, depending on the ambient temperature (8ºC and 25ºC).

Opis:
This paper examines the effect of an external preheating system for an internal combustion engine on fuel consumption, CO2 emissions, and cabin temperature of a Euro4 vehicle. A 1 kW electric system powered by 220 V was installed in series in the cooling system of a vehicle with a compression-ignition engine of 2.5 dm3 capacity. The tests were carried out in simulated urban driving conditions (distance of 4.2 km), extra-urban driving conditions (distance of 17 km), and during idling at cold-start temperatures ranging from -10oC to 2oC. Preheating the engine under simulated city conditions reduces fuel consumption by 2.64 dm3/100 km and increases the supply air temperature immediately after engine start-up. Due to the preheater being powered from an external power grid, the cost per trip and total CO2 emissions are increased. Assuming renewable energy sources, CO2 emissions would be reduced the most for the stationary tests after engine preheating. In contrast, emissions would be reduced the least for extra-urban driving.

Opis:
Spark-ignition (SI) engines are highly susceptible to excess emissions when started at low ambient temperatures, a phenomenon which has been widely discussed in the literature. Direct injection diesel engines feature a markedly different fuelling and combustion strategy, and as such their emissions behaviour is somewhat different from gasoline engines. The excess emissions of diesel engines at low ambient temperatures should also differ. The aim of this study was to compare excess emissions of gaseous and solid pollutants over a legislative driving cycle (the New European Driving Cycle, NEDC) following cold start at a low ambient temperature for both engine types. This paper examines emissions at low ambient temperatures with a special focus on cold start; emissions are also compared to start-up at a higher ambient temperature (24 °C). The causes of excess emissions and fuel consumption are briefly discussed. A series of tests were performed on European Euro 5 passenger cars on a chassis dynamometer within an advanced climate-controlled test laboratory at BOSMAL Automotive Research and Development Institute, Poland. Emissions data obtained over the Urban Driving Cycle by testing at 24 °C and at –7 °C, are presented for a selection of modern Euro 5 gasoline and diesel vehicles representative of the European passenger car fleet. A full modal emissions analysis was also conducted at 24 °C and at –7 °C over the NEDC. Emissions and fuel consumption were substantially higher at –7 °C than at 24 °C.
Celem niniejszej pracy była analiza problemu podwyższonej emisji związków szkodliwych spalin przy eksploatacji samochodów osobowych w niskich temperaturach otoczenia i porównanie emisji gazowych związków szkodliwych spalin i cząstek stałych z samochodów osobowych spełniających wymagania Euro 5 w czasie homologacyjnego testu jezdnego NEDC, rozpoczynającego się od rozruchu zimnego silnika, wykonywanego w normalnych i niskich temperaturach otoczenia. Przeprowadzono analizę wyników badań, uzyskanych w laboratorium emisji spalin Instytutu Badań i Rozwoju Motoryzacji BOSMAL, w zakresie emisji związków szkodliwych spalin w testach prowadzonych w temperaturach otoczenia +24 °C i –7 °C, dla nowoczesnych samochodów napędzanych silniami ZI i ZS, spełniających wymagania Euro 5. Stwierdzono znacznie podwyższony poziom emisji związków szkodliwych i zużycia paliwa w testach wykonywanych w ujemnych temperaturach otoczenia. Przyczyny podwyższonej emisji i zużycia paliwa w czasie rozruchu zimnego silnika i w czasie jego eksploatacji w niskich temperaturach otoczenia zostały przeanalizowane i opisane.
