Opis:
The article discusses the issue of the impact of wind force and direction on fuel consumption and the emission of harmful exhaust gases on the selected flight route. The focus was on percentage changes in fuel consumption and emissions of individual harmful exhaust gas compounds depending on the wind speed and the direction from which it interacts with the aircraft. The analysis was carried out for three different flight levels, in order to compare changes in fuel consumption and emissions also in terms of flight altitude, however the following article focuses only on one level - FL240.

Opis:
Fuel consumption achieved in the New European Driving Cycle (NEDC) could be 50% lower than the fuel consumption in real driving conditions and in the case of emissions of regulated toxic compounds the differences could even be much greater. In order to bring the results achieved in official tests closer to real life figures, the European Commission introduced in 2017 the Worldwide Harmonized Light Vehicles Test Procedure (WLTP), which replaced the NEDC. In this article the results of fuel consumption and exhaust emissions for 3 cars fitted with engines of the same displacement but with direct and indirect gasoline injection, determined according to the NEDC and WLTC were presented. The results show that the effect of driving cycle on the fuel consumption is equivocal - for one car, fuel consumption was higher in the WLTC; for the other one in the NEDC; and for the third one, fuel consumption achieved in both driving cycles was practically the same. Emissions of regulated exhaust compounds, except for THC, obtained in the WLTC were higher than in the NEDC driving cycle.

Opis:
The Euro 5 limits for L-category vehicles are applicable since 2020 and for this reason there is lack of studies examining the emissions of this category. In this study we tested a 1000 cm3 Euro 5 motorcycle over the World Harmonized Motorcycle Test Cycle (WMTC). The gaseous pollutants were approximately half of their respective limits. The cold start (first 2 minutes) contributed to the majority of the emissions. The solid particle number emissions were also 6.5 times below the limit for passenger cars, but the particles not counted with the current methodology were around 2 times higher. High concentrations of volatiles were emitted at the high speed part of the cycle.
