Hackathon and security resilience evaluation of the level 2 concept: Outcome of the evaluation with the hackathon. Deliverable D3.5

Pollutant emissions of road vehicles have reduced significantly thanks to the development and application of effective and often complex emissions control systems. Tampering of these systems by vehicle owners leads to elevated tail-pipe emissions, up to uncontrolled levels of vehicles of decades ago. Tampering poses a large environmental risk...

Implementation of anti-tampering measures into the existing legislative framework. Deliverable D3.3

Pollutant emissions from road vehicles have reduced significantly thanks to the development and application of effective and often sophisticated emissions control systems. Tampering of these systems leads to elevated emissions comparable to uncontrolled levels of vehicles of decades ago. Therefore, a small share of tampering potentially leads to...

Euro VI technologies and costs for Heavy Duty vehicles: The expert panels summary of stakeholders responses

This report is the result of the work carried out under on the European Commissions' call for tender regarding “Technical support for the Commission DG Environment on the development of Euro 5 standards for light-duty vehicles and Euro VI standards for heavy-duty vehicles” (Reference: ENV.C.1/SER/2004/0039). A consortium of TNO Automotive in...

Comparison of the particle size distribution and emissions from heavy-duty diesel engines and gas engines for urban buses

N2O-emissions of LD and HD vehicles

N2O emission of HD vehicles

N2O is known to be a greenhouse gas with a high global warming potential, approximately 296 times higher than that of CO2 [11]. In road vehicles N2O is mostly formed by reactions in the exhaust catalyst. The IPCC (Intergovernmental Panel on Climate Changes) uses emission factors from research performed in the late 1980's and early 1990's to...

Jaarrapport 2002 Steekproefcontrole Programma Vrachtwagens 2001-2003

In 2002 zijn 22 van de in totaal 30 geplande vrachtwagens voor het project Steekproef controleprogramma vrachtwagens 2001-2003 getest. Daarnaast zijn er twee correlatiemotoren gemeten op de motorproefstand en de rollenbank. In de aangetroffen afstelling voldeden 6 voertuigen niet aan de emissie eis voor NOx en 8 niet aan de eis voor deeltjes....

Audi Duo demonstration project: Environmental comparision and user survey

This paper describes the results and conclusions of a methodology for the assessment of environmental performance. This methodology was applied to a demonstration project conducted in the Netherlands with 10 Audi Duo parallel hybrid vehicles. During the course of the project, the vehicles were driven by a wide range of users and user groups. By...

Requirements for homologation, legislation and test cycles of vehicles with advanced powertrains

Traditionally, In-Use Compliance testing is closely related to homologation legislation, as in most cases the IUC test is a derivative from the type approval test. As it is the aim of this paper to explore the future of IUC testing, this can be studied best on the basis of expectations for future homologation test procedures that also include...

Options for practical in-use compliance testing of HD vehicles

In 1994 TNO Automotive started its HD vehicle In-use Compliance programme on request of the Dutch Ministry of Spatial Planning, Housing and the Environment. Until now, it has been possible to simulate the homologation test procedure with acceptable accuracy on the vehicle (using a chassis dynamometer), rather than testing the engine on an engine...

Steekproefcontrole Programma Vrachtwagens 1998-2000

Dit is het 4e rapport van het steekproef controleprogramma vrachtwagens. Het behandelt de proeven in het tijdvak 1998-2000.

Matador: final report of task 2

In Task 2 of the MATADOR-project1 measurement methods have been developed for the evaluation of the energy consumption and emissions of vehicles with advanced propulsion systems, such as battery-electric, hybrid-electric and fuel cell vehicles. Based on an inventory of existing and prospective standard test procedures and of technology-specific...
