Despite that Heavy-Duty Vehicles (HDVs) represent a small part of the overall vehicle population they have been identified as one most important contributors to air pollution. This is reasons why HDV emissions regulations are becoming more and stringent worldwide. Following this trend, Europe introduced Euro VI standard which includes emission limits for hydrocarbons, PM NOx, while first time limit solid PN was set. At same increased concern regarding greenhouse gas led series initiatives...
Tyre particles are generated by shear forces between the tread and road or volatilisation. abrasion (wear) contributes from one-third to half of microplastics unintentionally released into environment. The major part ends up in soil, a considerable amount is aquatic environment, small percentage becomes airborne. Nevertheless, tyre 5–30% transport particulate matter (PM) emissions. This corresponds approximately 5% total ambient PM particle mass size distribution peak at around 20 100 μm,...
Euro VI emission standards for heavy-duty vehicles (HDVs) introduced the first time limits solid particle number (PN) and NH3 emissions. EU regulation also includes a Portable Emissions Measurement System (PEMS) based test at type approval, followed by in-service conformity (ISC) testing. A comprehensive study on real-time on-road emissions of NOx, NH3, N2O PN from HDV equipped with Diesel Oxidation Catalyst (DOC), Particle Filter (DPF), Selective Catalytic Reduction (SCR) system an Ammonia...
Passenger cars are an important source of air pollution, especially in urban areas. Recently, real-driving emissions (RDE) test procedures have been introduced the EU aiming to evaluate nitrogen oxides (NOx) and particulate number (PN) from passenger during on-road operation. Although RDE accounts for a large variety real-world driving, it excludes certain driving situations by setting boundary conditions (e.g., relation altitude, temperature or dynamic driving). The present work investigates NOx, NO
European regulation 2016/427 (the first package of the so-called Real-Driving Emissions (RDE) regulation) introduced on-road testing with Portable Measurement Systems (PEMS) to complement chassis dynamometer laboratory (Type I) test for type approval light-duty vehicles in Union since September 2017. The Not-To-Exceed (NTE) limit a pollutant is Type I multiplied by conformity factor that includes margin additional measurement uncertainty PEMS relative standard equipment. variability measured...
Regulated and unregulated emissions from two Euro 6b diesel passenger cars tested using three different blends of hydrotreated vegetable oil (HVO), fossil commercial (B7) were investigated at 23 °C −7 the World harmonized Light-duty vehicle Test Procedure Vehicle Emission Laboratory European Commission Joint Research Centre Ispra, Italy. The HVO used were: Neat (100 vol% HVO), 30 7 HVO. One vehicles was also on-road following a RDE compliant route. Overall, use did not lead to fuel related...
Light-duty vehicle emission regulation in the European Union requires dilution of whole exhaust a tunnel with constant volume sampling prior to measurements. This methodology avoids measurement uncertainties associated direct raw measurements from tailpipe, such as flow determination, pressure pulsations, differences response time between and instrument signals, or their misalignment. Transfer tubes connecting tailpipe different lengths, mixing gas air may increase performed at facilities....
Abstract Background Road transport is an important contributor to the European Union’s total greenhouse gas emissions. This study aims at summarizing methane (CH 4 ) and nitrous oxide (N 2 O) exhaust emissions from L-category, light-duty heavy-duty vehicles in Union. The assessment based on measurements carried out Vehicle Emission Laboratory of Joint Research Centre between 2009 2019. chemical composition a fleet 38 L-category Euro 1 (2- 3-wheelers, small quadricycles such as quads...
The Particle Measurement Programme Informal Working Group (PMP-IWG) coordinated a global interlaboratory study (ILS) on brake wear particle emissions with the participation of 16 testing facilities. Two articles present main outcomes ILS: (I) Particulate matter mass (PM), and (II) Number (PN) emissions. test matrix covered wide variety systems configurations. tested disc brakes were found to emit PM2.5 PM10 that varied between 0.8–4.0 mg/km 2.2–9.5 per brake, respectively, depending type...
Particulate Matter (PM) air pollution has been linked to major adverse health effects. Road transport still contributes significantly ambient PM concentrations, but mainly due the non-exhaust emissions from vehicles. For first time worldwide, limits for have proposed by European Union upcoming Euro 7 step. these reasons, interest in brake increased past few years. Realistic emission factors are necessary accurately calculate contribution of also estimate reduction potential new or existing...
The effect of lubricants on nanoparticle formation in heavy-duty diesel exhaust with and without a continuously regenerating particulate filter (CRDPF) is studied. A partial flow sampling system particle size distribution measurement starting from 3 nm, approximately, used. Tests are conducted using four different lubricant formulations, very low sulfur content fuel, steady-state driving modes. well-documented test procedure was followed for each test. Two kinds were observed, both found to...
Light duty vehicle emissions legislation requires calibration and validation of Condensation Particle Counters (CPCs). A workshop was organized at the European Commission's Joint Research Centre (JRC, Ispra, Italy) to study effect test aerosol materials (of their chemical composition) on CPC results. The counting efficiencies Combustion Aerosol STandard (CAST) particles 23 nm (steep part efficiency curve) were found be similar (0.53) those heavy diesel engine (0.57), Emery oil either or...
The particle measurement programme (PMP) used a system (reference (RS)) to quantify the number emissions of several vehicles. RS was circulated around laboratories represent an internal standard. During exercise dilution factors, losses and volatile removal efficiencies were regularly checked. In parallel with RS, some labs employed their own systems (lab (LS)) determine same test Comparisons between results from LS showed that different instruments capable measuring within ±15% across...
The particle number method was introduced in the Euro 5/6 light-duty regulation and will also be VI heavy-duty regulation. legislation requires yearly calibration or validation of systems with monodisperse aerosol for determination concentration reduction factor (PCRF); however, there are some open issues, like material to used. In this paper, we describe new system from AVL (APC) its procedure which gives repeatability PCRFs after 1 year better than ±6% (two standard deviations...
A Euro 4 Light-Duty Diesel vehicle equipped with a diesel particulate filter (DPF) was circulated to 9 labs where repetitions of the current regulatory New European Drive Cycle (NEDC) were conducted. Regulated gaseous and improved (with cyclone, temperature 47 ± 5°C, constant face velocity, high precision balance at all labs) mass (PM) measurements also reference particle number (PN) measurement system measuring non-volatile particles along test vehicle. Labs tested their own PN systems...
A solid particle number limit was applied to the European legislation for diesel vehicles in 2011. Extension gasoline direct injection raised concerns because many studies found particles below lower size of method (23 nm). Here we investigated experimentally feasibility lowering this size. nano condensation nucleus counter system (nCNC) (d50% = 1.3 nm) used parallel with counters (CPCs) 3 nm, 10 nm and 23 at various sampling systems based on ejector or rotating disk diluters having thermal...
The solid particle number method was introduced in the European Union (EU) light-duty legislation for diesel vehicles to ensure installation of best-available technology particles (i.e., wall-flow particulate filters) without uncertainties volatile nucleation mode and need large investment purchasing equipment. Later it extended gasoline with direct injection engines, heavy-duty engines (both compression ignition positive ignitions) non-road mobile machinery engines. Real Driving Emissions...
