“…In general terms, the addition of biofuels reduces the emission of soot, hydrocarbons, and carbon monoxide, but may intensify the emission of nanoparticles and oxidised derivatives of PAHs [149]. In research on bioadditives present in gasolines, it was found that MTBE and ETBE slightly increase NO x emissions [142], while the addition of bioethanol may lead to a decrease in NO x concentration [150]. The literature also indicates the formation of combustion byproducts [151] such as formaldehyde and acetaldehyde [142,152,153], acetone, propanal, benzaldehyde and tolualdehyde [154], and mono-and dicarboxylic acids [155,156].…”

The article offers a comprehensive examination of vehicle emissions, with a specific focus on the European Union’s automotive industry. Its main goal is to provide an in-depth analysis of the factors influencing the emission of microcontaminants from light-duty vehicles and the challenges associated with their removal via exhaust aftertreatment systems. It presents statistical insights into the automotive sector and explores the relationships between vehicle categories, fuel types, and the emission of regulated and nonregulated pollutants, as well as relevant legal regulations such as the European Emission Standard. The article delves into the characteristics of vehicle exhaust, compares exhaust-gas aftertreatment systems, and introduces factors affecting emissions from gasoline engines, including downsizing, fuel composition, and engine operating parameters. It also considers the impact of driving style, start–stop systems, and related factors. Concluding, the article offers an overview of vehicle-testing procedures, including emission tests on dynamometer chassis and real driving emissions. With the growing global vehicle population and international environmental regulations, a focus on solid particles containing microcontaminants is paramount, as they pose significant risks to health and the environment. In summary, this article provides valuable insights into vehicle emissions, significantly contributing to our understanding of this crucial environmental issue.

The research was divided into two stages. The first stage of work was to perform empirical research using the Perkins engine. The test stand was equipped with an exhaust gas composition analyzer, a pressure sensor enabling measurement of pressure in the engine cylinder and a crankshaft position sensor. This stage of research was realized for diesel and UCOME fuel. The second stage was a simulation test. The Zeldovich model of thermal NO formation in compression ignition engines was used for calculations. Theoretical methods were compared with the results obtained in empirical tests. It was found that the most similar results of tests when powering the engine with UCOME fuel were obtained thanks to the GRI-MECH 3.0 (G) method. On the basis of this method, coefficients of the reaction rate of NO formation in an internal combustion engine, which is powered by the higher generation alternative fuel (Sikora et al. (S) method) were developed. For the calculation tests the values of the experimentally determined pressures were used. The proposed method can be used in simulation tests of a diesel engine running on FAME fuels with similar physical and chemical properties as the UCOME fuel. This will significantly reduce the costs of such tests, as some empirical tests can be eliminated by the conclusions of the simulation tests.

Evaluation of the effect of the addition of bioethanol to gas oil on coking diesel engine injector terminals

The article presents the results of empirical research and their analysis regarding the impact of diesel oil and diesel oil mixture with bioethanol on coking the test injector nozzles of the XUD9 engine from PSA. The research included three fuel deals: diesel fuel as the base fuel and diesel oil mix with ONE10 bioethanol (10% bioethanol plus diesel oil (V/V)), ONE20 (20% bioethanol plus diesel oil (V/V)). They were conducted on the basis of CEC PF-023 developed by CEC (Coordinating European Council). Each of the above-mentioned fuels was tested using a new set of injectors. The propensity of the fuel for coking the injector tips was expressed as a percentage reduction in the air flow through the nozzles of each injector for the given sheer increments. The test result was the average percentage of airflow reduction for all nozzles at 0.1 mm spike increments and was measured according to ISO 4010 "Diesel engines. Calibrating nozzle, delay pintle type”. The test results for individual atomizers of the above-mentioned test engine in the area of sediment formation from flowing fuel shown a lower tendency to coke the injectors using diesel fuel-bioethanol in comparison to the use of pure diesel oil. Based on the CEC PF-023 test, it can be noticed that the level of contamination of the tested injectors for ONE10 fuel is about 3% lower, and for ONE20 fuel is about 4% lower than the level of pollution for diesel fuel.
