Solid particle number emissions of 56 light-duty Euro 5 and Euro 6 vehicles

Tero Lahde et al.

Summary: The study found that SPN emissions from gasoline direct injection and diesel vehicles with particulate filters decreased with improving emission standards, while emissions from gasoline port-fueled injection vehicles did not improve. Among vehicles compliant with recent European regulations, gasoline port-fueled injection vehicles had the highest emissions.

Secondary Organic and Inorganic Aerosol Formation from a GDI Vehicle under Different Driving Conditions

Weihan Peng et al.

Summary: This study investigated the primary emissions and secondary aerosol formation from a gasoline direct injection (GDI) passenger car under different driving conditions. The results showed higher emissions and formation of secondary organic aerosols during cold-start cycles. The total mass of secondary aerosols exceeded primary particle emissions and was mainly composed of inorganic aerosols.

Detailed Characterization of Solid and Volatile Particle Emissions of Two Euro 6 Diesel Vehicles

Barouch Giechaskiel et al.

Summary: This study investigates the particulate emissions of two light-duty Euro 6 vehicles by measuring them simultaneously at the tailpipe and the dilution tunnel. The results show that while the solid particle number emissions remain within the applicable limit, the number emissions of volatile particles, taking into account the emissions during regeneration, are significantly higher.

Particle emissions measurements on CNG vehicles focusing on Sub-23nm

Zisimos Toumasatos et al.

Summary: The study found that passenger cars operating on compressed natural gas (CNG) had lower solid particle number emissions compared to gasoline vehicles when the particle size threshold was 23 nm, but similar emissions when the threshold was lowered to 10 nm or 2.5 nm. Specifically, the Euro 6 b vehicle exceeded the Euro 6 emission standard for 2.5 nm particles, while emissions for 23 nm particles were significantly lower than the limits for CNG and gasoline. Particle size distributions revealed particles below the regulated 23 nm limit, indicating the current threshold may be insufficient for particle emission testing.

Overview of Vehicle Exhaust Particle Number Regulations

Barouch Giechaskiel et al.

Summary: Vehicle emissions, particularly particulate matter, contribute significantly to urban air pollution. Regulations worldwide, including those in the EU, have introduced measures to monitor and control PM emissions by implementing particulate number measurement methods. Other countries, such as China and India, are also beginning to adopt similar approaches to address vehicle emissions.

Uncertainty of laboratory and portable solid particle number systems for regulatory measurements of vehicle emissions

Barouch Giechaskiel et al.

Summary: In the European Union's emissions regulations, vehicles are required to comply with limits for solid particles >23 nm, which are measured using particle number (PN) systems. The technical specifications of laboratory and portable on-board systems differ, leading to varying measurement uncertainties. Additionally, particles may be lost in transfer lines, making comparisons between different sampling locations challenging. Size dependent counting efficiency of the systems can also result in discrepancies, especially for particles sizes close to the decreasing steep part of the curves.
