Dutch in-service emissions testing programme 2015-2018 for heavy-duty vehicles: status quo Euro VI NOx emission

In opdracht van het Ministerie van Infrastructuur en Waterstaat voert TNO het steekproefcontroleprogramma voor vrachtwagens en bussen uit. In dit programma meet TNO, op regelmatige basis, de uitlaatgasemissies van deze voertuigen om te onderzoeken hoe schoon ze in de praktijk zijn en of ze aan de Europese normen voldoen. Euro-VI voertuigen...

NOx emissions of heavy-duty vehicles with Euro VI certified engines

In the Dutch in-service emissions testing programme, the nitrogen oxide (NOx) emissions of 46 vehicles with Euro VI certified engines were measured during normal daily operation using the Smart Emission Measurement System (SEMS). To screen the in-service conformity, a number of vehicles were tested over the prescribed in-service conformity test...

On-road emission measurements with PEMS on a Mercedes-Benz Atego Euro VI N2 heavy-duty truck

Commissioned by the Ministry of Infrastructure and Water management of The Netherlands, TNO Sustainable Transport and Logistics regularly performs measurements on heavy-duty vehicles to determine the in-service performance and durability of the tail-pipe emissions under representative driving conditions. A Euro VI heavy-duty N2 class truck, the...

Tail-pipe NOx emissions Euro VI buses in daily operation in the Netherlands

In the framework of the in-service testing programme for heavy-duty vehicles for the Ministry of Infrastructure and Water management, the nitrogen oxide emissions (NOx) of five Euro VI busses for public transport were measured during real-world operation during everyday’ s use with the Smart Emissions Measurement System ‘SEMS’ [TNO 2016a]. Each...

Tail-pipe NOx emissions of refuse collection vehicles with a Euro VI engine in daily operation in the Netherlands

In het kader van het Nederlandse steekproefcontroleprogramma voor vrachtwagens en bussen, dat TNO uitvoert in opdracht van het Ministerie van Infrastructuur en Waterstaat, zijn de stikstofoxiden (NOx) emissies van negen Euro VI vuilnisauto’s gemeten tijdens representatieve inzet in de dagelijkse praktijk met het Smart Emissions Measurement...

Emissions testing of two Euro VI LNG heavy-duty vehicles in the Netherlands: tank-to-wheel emissions

In the framework of the in-service testing programme of trucks and buses, carried out by TNO for the Ministry of Infrastructure and Water Management, an on-road emissions testing programme was conducted to determine the criteria pollutants, greenhouse gas (GHG) emissions and fuel consumption of two modern Euro VI trucks running on LNG (liquefied...

Mogelijkheden om manipulatie van AdBlue-systemen bij vrachtwagens vast te stellen en terug te dringen - eindrapport

Begin 2017 kwam via de media naar voren dat manipulatie plaatsvindt van systemen die op vrachtwagens zitten om de schadelijke uitlaatgasemissies terug te dringen. Het manipuleren houdt in dat in een vrachtwagen een kastje wordt ingebouwd of de motorsoftware wordt aangepast zodat het emissiebeheersingssysteem wordt uitgeschakeld. Het uitschakelen...

Review of RDE legislation: legislation text, evaluation methods and boundary conditions on the basis of RDE test data

The European Commission has the mandate to keep under review the procedures, tests and requirements, as well as the test cycles used to measure vehicle emissions as part of the Euro-5/6 legislation. The development of the new Real Driving Emissions (RDE) legislation is considered to be the way forward to secure low on-road emissions in the years...

Inzetbaarheid van zero emissie bussen in Nederland

In 2012 ondertekende de Minister van het Ministerie van Infrastructuur en Milieu de Green Deal Zero Emissie Busvervoer, met als ultieme doel een volledig emissievrije bussenvloot in 2025. Dat betekent een ambitie om in 2025 alle OV-bussen te hebben voorzien van elektrische aandrijving, waaronder batterij-elektrisch en waterstofelektrisch....

SEMS operating as a proven system for screening real-world NOx and NH3 emissions

NOx emissions of heavy-duty and light-duty diesel vehicles depend strongly on the driving conditions. The introduction of combined emission reduction technologies in Euro VI vehicles have demonstrated that NOx emissions become less predictable when the data is based on relatively short test cycles. Due to the decreased predictability with the...

Report on fuel consumption meter requirements for LD vehicles

This report deals with the development of requirements for fuel consumption meters as a measure for the reduction of CO2 emissions of light-duty vehicles. The work is done for the European Commission, DG Enterprise and Industry for specific contract SI2.629009, “Development of a complete test procedure for fuel consumption meters in light-duty...

Study on tyre pressure monitoring systems (TPMS) as a means to reduce light-commercial and heavy-duty vehicles fuel consumption and CO2 emissions

Elektrische ov-bus moet prestatie opschroeven

Rond 2025 rijilen alle openbaarvervoerbussen in ons land zonder uitstoot van schadelijke emissies, zo wil het ministerie van lnfrastructuur en Milieu Maar hoe zit het met de prestatie tussen bijvoorbeeld elektrische bussen en de huidige dieselbussen? TNO onderzocht de prestaties van een rz meter lange elektrische bus in de praktijk: dat kan nog...

One year monitoring of 26 electric vehicles

The Dutch government regards electric driving as a very promising option to make our future automobility more sustainable, to strenghten the Dutch energy position and to give our economy a structural boost. Therefore, it was decided to gain experience of electric driving through field tests with the Dutch Government's Public Works Department....
