Abstract:
As a main measure to promote the development of China’s energy–saving and new energy vehicles, the Phase V fuel consumption regulation is dramatically different from the past four phases, especially in the test procedure, moving from the New European Driving Cycle (NEDC) to the worldwide harmonized light duty test cycle (WLTC) and corresponding test procedure (WLTP). The switch of test procedure will not only affect the effectiveness of technologies but also change the fuel consumption target of the industry. However, few studies have systematically investigated the impacts of the new WLTP on

Abstract:
The switching from new European driving cycle (NEDC) to worldwide harmonized light vehicles test procedure (WLTP) will affect the energy consumption of plug-in hybrid electric vehicle (PHEV), and then affect the new energy vehicle (NEV) credit regulation and subsidy policy for PHEVs. This paper reveals the impact on energy consumption, NEV credit regulation, and subsidy policy for PHEV in the Chinese market of the switching from NEDC to WLTP based on qualitative analysis and quantitative calculation. The results show that the WLTP procedure is stricter than NEDC in the determination of road lo

Abstract:
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

Abstract:
The use of biofuels in vehicles becomes more advantageous than the consumption of fossil fuels, mainly because it uses renewable sources of energy. Recently there are some concerns about biodiesel sources, and hydrotreated vegetable oils (HVO) appear as a possible advanced solution. To understand the effect that the implementation of the new and old European type-approval test cycles (NEDC e WLTP) has on the results of these fuels considering pollutant emissions and fuel consumption results, a EURO V vehicle was subject to these cycles and also to engine performance evaluation tests.

I analysen användes standardkörcykeln WLTP (World harmonized light vehicle test procedure) som delades in i tre körcykler: stadskörning, blandad körning och motorvägskörning. Verkningsgradmatrisen beskriver växellådans verkningsgrad i förhållande till varvtal och moment.

In general terms the WLTP appears to be a significant improvement compared to the NEDC. The main differences between two test procedures are identified and thei

Pollutants emissions and fuel economy tests for passenger cars differ from region to region of the world, since different driving condition and vehicle fleet characterize different geographical areas. In particular, the European type approval procedure for passenger cars uses as reference cycle the New European Driving Cycle (NEDC), which is nowadays not representative of real driving conditions. Therefore, the European Commission has planned to introduce the Worldwide Harmonized Light Duty Test Procedure (WLTP) from September 2017.

Det här projektet handlar om att utveckla en metod för real driving emission (RDE). RDE är ett komplement till Worldwide Light Duty Test Procedure (WLTP) som kommer att ersätta New European Driving Cycle (NEDC). Dessa cykler och metoder används för att mäta personbilars avgaser. Huvudanledningen till varför NEDC ska bytas ut är för att körcyklerna inte längre är realistiska och reflekterar inte hur en bil presterar egentligen. Detta har lett till att bilar har högre bränsleförbrukning och högre avgasutsläpp när dom körs i trafiken jämfört med resultaten från NEDC.Metoden utvecklades genom hänv
