“…The highest THC emission factor was recorded for the diesel vehicle with the highest engine displacement (D4), whereas the lowest THC emission factor was observed for the diesel vehicle with the lowest engine displacement (D1). The emission factor of THC (0.20 ± 0.18 g km -1 ) for gasoline cars reported by Kerbachi et al (2017) was slightly higher than the respective emission factors obtained in the preset study. The average CO emission factors were 1.08 g km -1 (0.256-2.43) g km -1 and 0.403 g km -1 (0.115-1.10) g km -1 for gasoline and diesel vehicles, respectively, which were comparable to the CO emission factor (0.81 ± 0.69 g km -1 ) reported by Kerbachi et al (2017).…”

This study investigated the chemical composition (carbonaceous species, water-soluble ions and metal elements) of fine particulate matter (PM 2.5 ) emitted by gasoline and diesel vehicles. The emission factors of PM 2.5 , total hydrocarbons (THC), carbon monoxide (CO) and oxides of nitrogen (NO x ) were also determined. The emission measurements were performed for four gasoline and four diesel vehicles on a dynamometer with a constant volume sampling system. Vehicles having larger engines and higher accumulated mileages had higher emission factors of gaseous pollutants. Moreover, the average emission factor of NO x was about 30 times higher for diesel vehicles than for gasoline vehicles. The average PM 2.5 emission factors for gasoline and diesel vehicles were 1.57 mg km -1 and 57.8 mg km -1 , respectively. The ratio of organic carbon to elemental carbon (OC/EC) was found to be a good indicator of gasoline vehicle emissions (OC/EC > 1) and diesel vehicle emissions (OC/EC < 1). Among water-soluble ions, Ca 2+ and SO 4 2had the highest contribution to PM 2.5 emitted by gasoline vehicles, while NO 3 -, SO 4 2and Ca 2+ had the highest contribution to PM 2.5 emitted by diesel vehicles. Na, Ca, Fe and Zn were the top four metal elements in terms of their contributions to PM 2.5 mass for both types of the vehicles, while Cd, Cr, Pb and Sb were some of the toxic metal elements detected in PM 2.5 .

“…Other analysers used are flame ionisation detection (FID) for the determination of hydrocarbons and methane and chemiluminescent (CLD) for the determination of nitrogen oxides. Other methods used to measure exhaust emissions are analytical methods, mainly chromatographic (including flame ionisation or chemiluminescence detection) and spectroscopic [1,6,10,13,16,25,32]. Among them we can distinguish the less known ones, e.g.…”

The BAT-CELL Bio-Ambient-Tests method is based on the assessment of the influence of the actual toxicity of various types of gas mixtures on living cells, taking into account the additive synergism. Work has been carried out on the application of the BAT-CELL method for testing engine exhaust gases. The application of computational fluid mechanics using Ansys Fluent made it possible to analyse the flow of engine exhaust gases through the aspiration system used, including analysis of shear stress values and their uniformity distribution on the bottom wall of the sampler containing cell culture on the bottom wall of the sampler. The appropriate flow rate of exhaust gases through the aspiration system and the shape of aspiration tubing for the sampler were selected in order to enable uniform contact of gas particles with the cell surface and not to damage them mechanically. The simulation results were verified in real-life tests and confirmed the theoretical assumptions.

“…The emission of unburned HCs can be taken into consideration as the engine's combustion performance indicator. During the incomplete combustion process, the HC emission affects the emissions of other pollutants, especially ultrafine particles and nitric oxides [28,30,56]. On the contrary to the nitric oxides, carbon monoxide or soot, the increase of the HC emission is observed also during the deceleration [28,45].…”
