Use of a vehicle-modelling tool for predicting CO2 emissions in the framework of European regulations for light goods vehicles

The reduction of CO2 emissions and fuel consumption from road transportation constitutes an important pillar of the EU commitment for implementing the Kyoto Protocol. Efforts to monitor and limit CO2 emissions from vehicles can effectively be supported by the use of vehicle modelling tools. This paper presents the application of such a tool for...

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...

Evaluatie en advies filevorming 80 km zones

Aanleiding evaluatie en advies filevorming 80 km zones Op 1 november 2005 is op vier trajecten de maatregel ’80 km/u met strenge handhaving’ (in dit rapport aangeduid met 80 km SH) ingevoerd. Deze maatregel is bedoeld om de luchtkwaliteit langs de autosnelweg te verbeteren. Na de invoering blijkt dat de 80 km maatregel op enkele van deze...

In-use compliance programme passenger cars: annual report 2004

Driving style and traffic measures: Influence on vehicle emissions and fuel consumption

This paper describes the influence on vehicle emissions and energy consumption of different vehicle parameters and driving style as well as of traffic measures taken in order to increase transport safety or to reduce traffic jams. This should allow the Flemish Regional Government to perform more realistic modelling of the impact of transport on...

In-use compliance programme passenger cars: Annual report 2003

This report presents a general overview of the results of the Dutch In-Use Compliance programme for passenger cars over the year 2003. The work in this year was executed under a contract with the Dutch Ministry of Housing, Spatial Planning and the Environment for the period 2000-2003. The passenger car in-use compliance programme basically...

In-use compliance programme - Overview of Automotive LPG vehicles 1999-2003

This report presents a general overview of the results of automotive LPG vehicles that have been tested within the framework of the Dutch In-Use Compliance programme for passenger cars over the years 1999 to 2003. The work in these years was executed under a contract with the Dutch Ministry of Housing, Spatial Planning and the Environment. The...

Assessment of the influence on vehicle emissions of driving style, vehicle technology and traffic measures

The influence of traffic measures and driving style on different vehicle emissions and on primary energy consumption, and the definition of vehicle parameters influencing the relation between them, is an interesting issue to be assessed in order to allow more realistic estimations of the impact of transport on air pollution and an optimisation...

Real-world driving behaviour of cars

A methodology was developed to quantify the emissions of traffic congestion on Dutch motorways. In the first phase of the project a categorisation of traffic flow conditions on motorways was elaborated. This categorisation was eventually linked to a traffic monitoring system that operates with induction loops. In the second phase trips were...

In-use compliance programme: Annual report 2001

Interpretation of driving style tips: application of the major driving style tips of "New Style Driving" by passenger car drivers and the effects on fuel consumption and tail pipe emissions

Besides the applied engine and vehicle technology, the fuel economy of a car is also influenced by the behaviour of its driver. In the order to address the influence of a driver on the fuel consumption of road vehicles, the Dutch government and Novem have developed a national programme called "The New Driving Force" (Het Nieuwe Rijden). The main...

Real-world driving behaviour

With increasing complexity of engine management system there is a tendency for traditional driving cyles to become further and further removed from reality. So for a sensible evaluation of emissions and fuel consumption of road vehicles in the field there is an urgent need for 'real-world' driving patterns. Existing 'standard' driving cycles can...

In-use compliance testing of passenger cars in the Netherlands

In 1987 TNO Automotive started the execution of a large scale in-use compliance program for passenger cars. The initial goal of the program was: 'Monitoring the emission performance of passenger cars in-use and relating this performance to the situation at type approval'. In the early years the program proved to be very useful for detection of...

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...
