Emissions from internal combustion vehicles are currently not properly monitored throughout their life cycle. Remote emission sensing (RES) is a technology that can measure emissions under real driving conditions without contact. Current light extinction based RES systems capable of providing factors for various gases, but lack accuracy particulate matter (PM). Point Sampling (PS) an extraction-based technique gases as well particle metrics such black carbon or number. In this work, we...
The recently introduced Real Driving Emissions (RDE) light-duty vehicle emissions regulation requires testing with Portable Measurement Systems (PEMS) during type approval and in-service conformity. studies on the accuracy of PEMS today are limited. An inter-laboratory correlation exercise took place in Italy 2017. Eight laboratories measured exhaust from a Golden Euro 6 gasoline installed it, along individual lab’s own PEMS, following regulated laboratory method (bags dilution tunnel). data...
As part of the Zero Pollution Action Plan Green Deal, European Commission has set goal reducing number premature deaths caused by fine particulate matter (PM2.5) at least 55% 2030, compared to 2005 levels. To achieve this, aims introduce stricter limits. In urban areas, road transport is a significant source PM emissions. Vehicle originates from engine exhaust and tire, brake wear, as well dust resuspension. recent decades, application stringent emission limits on vehicle led adoption...
In the last years, in-use emissions of vehicles are measured on road with portable measurement systems (PEMS). PEMS cannot measure as accurately laboratory grade equipment, and studies their uncertainty have continued since appearance in market. this study we compared to equipment Italian laboratories testing a diesel “Golden” (i.e., reference) vehicle for two consecutive years. The results showed equal means carbon dioxide (CO2), nitrogen oxides (NOx), particle number (PN), variability ±5...
Five Euro 6 LPG (liquefied petroleum gas) bi-fuel passenger cars well representative of the Italian circulating fleet were tested in laboratory (in repeatable conditions on a chassis dynamometer) and road real traffic using portable emissions measurement system). The regulated unregulated exhaust energy consumptions measured with gasoline fuelling compared. All compliant limits over type-approval driving cycles RDE (Real Driving Emissions) tests except for particle number emission from only...
The aim of this work is the definition a pilot test procedure to carry on system testing and validation tests with locomotive engine aftertreatment pre-prototype called ENSPIRIT system, developed in framework FP7 European Project Eliminating NOx, SOx & Particulate Rail Transportation. Here it described study, processing procedure. A study has been conducted investigating legislation (both US EPA) dealing emission standards for locomotives, gathering fundamental information create driving...
This study assessed the potential for decreasing environmental impact of European road transport sector by exploiting biofuels. After processing available data on actual trends biofuels utilisation in sector, laboratory and on-road tests were conducted to compare emissions from a C-segment Euro 6d-TEMP passenger car fed with commercial reference petrol three experimental blends containing components renewable origin. Through Life Cycle Assessment methodology based measurement data, impacts...
Emissions from internal combustion vehicles are currently not properly monitored throughout their life cycle. Remote Emission Sensing (RES) is a technology that can detect emissions in real driving conditions without contact. Current RES systems, based on the measurement of light extinction exhaust plumes, capable providing emission factors for various gases, but lack accuracy particulate matter (PM). Point Sampling (PS) an technique extracts portions plume using gas analyzers measure...
