“…It should be emphasized that in the studies of many authors [5,38,[61][62][63], the total amount of nitrogen oxides was investigated independently of the studied fuels and combustion systems. However, two of the most dangerous nitrogen oxides, NO and NO 2 , often occurring together, have been measured in the experimental studies-of which nitrogen dioxide is considered the most dangerous due to its impact on human health and other living organisms [59,60].…”

“…In response to the depletion of natural energy resources and an increase in CO 2 emissions resulting from the combustion of fossil fuels, research on biomass fuel production is carried out worldwide [14][15][16][17][18][19][20][21][22][23]. The resulting different quality biodiesel liquid fuels [24][25][26][27][28], as well as biogas [29,30] nevertheless constitute a significant source of energy [31][32][33][34][35], especially for small farms. In such situations, a dual fuel combustion engine powering a generator [36,37] alternative, significantly limiting a farm's demand for energy from external sources and increasing level of independence of the indicated energy sources.…”

“…Because the biogas obtained in practice is characterized by the variable content of methane, carbon dioxide, and hydrogen sulphide, research is conducted in which the gas composition is simulated in order to discover phenomena and dependences having a significant impact on toxic exhaust components [55][56][57][58]. However, after analyzing the literature [42,43,59,60], one cannot get an unambiguous answer to the question of whether the solution is pro-ecological.…”

The aim of this study was to perform a comparative analysis of the unit gas emission value in the exhaust of a dual fuel diesel engine. The results of the effects of a diesel engine’s applications in biogas plants and the method for calculating mass gas emissions per unit of produced electricity are shown. The test was performed using a two-cylinder, naturally aspirated, liquid-cooled diesel engine. The diesel engine powered a generator connected to the grid. The engine was fed with liquid fuels—waste cooking oil methyl ester (UCOME) and diesel fuel (DF)—and with a gas fuel, biogas (BG). The engine ran at a constant rotational speed (2000 rpm ± 30 rpm) with variable load. The gas analyzer measured the amount of CO, NO, NO2, and PM (particulate matter) in exhaust gas. This gas content share was then converted to mass per engine generated energy unit. This experiment showed the effect of BG introduced to the intake manifold on fuel combustion, as well as an increase in CO and NO2 emission and decrease in NO and PM. In terms of dependence of exhaust emissions on the type of liquid fuel used, the use of UCOME as opposed to diesel fuel resulted in PM reduction and increase of NO emissions.

“…However, in the case of the tested engine, the trend reverses around the rotational speed of 1700 rpm. This is related to changes in the fuel pressure Energies 2024, 17, 328 9 of 16 level in the fuel supply system, and the pressure values are presented in the work of Krzaczek et al [41]. For a full engine load in the range of 1400 to 1600 rpm, the fuel pressure decreases from 90 MPa to 75 MPa and then increases linearly to 105 MPa at 2400 rpm.…”

The results of an experimental study of nitrogen oxide (NO) and particulate matter (PM) concentrations in the exhaust gas of a compression-ignition engine used in agricultural tractors and other commercial vehicles are presented. The engine was fueled with second-generation biodiesel obtained from used frying oils (classified as waste) and first-generation biodiesel produced from rapeseed oil as well as, comparatively, diesel fuel. Tests were conducted on a dynamometer bench at a variable load and a variable engine speed. The levels of PM and NO emissions in the exhaust gas were determined. The study showed significant environmental benefits of using first- and second-generation biodiesel to power the engine due to the level of PM emissions. The PM content, when burning ester biofuel compared to diesel fuel, was reduced by 45–70% on average under the speed and load conditions implemented. As for the concentration of nitrogen oxide in the exhaust gas, no clear trend of change was shown for the biodiesel in relation to the diesel fuel. The level of NO emissions in the range of full-power characteristics was found to be lower for both tested biofuels compared to diesel fuel at lower engine speeds by an average of 7–8%, while in the range of a higher rotation speed, the NO content in the exhaust gases was higher for the tested biofuels compared to diesel oil by an average of 4–5%. The realized engine performance tests, moreover, showed an unfavorable effect of the biodiesel on the engine energy parameters. In the case of biofuels, this was by more than 4% compared to diesel fuel.

“…Physically, FAME has higher viscosity than DF and higher end of distillation temperature, which poses some low-temperature issues [17]. Greater density results from high oxygen content [15], which further translate to lower calorific value and lower stoichiometric air requirement. Auto-ignition properties of FAME are similar to DF.…”

This study investigates combustion and emission characteristics of a contemporary single-cylinder compression ignition engine fuelled with diesel, fatty acid methyl esters (FAME) and hydrotreated vegetable oil (HVO). These two drop-in fuels have an increasing share in automotive supply chains, yet have substantially different physical and auto-ignition properties. HVO has a lower viscosity and higher cetane number, and FAME has contrary characteristics. These parameters heavily affect mixture formation and the following combustion process, causing that the engine pre-optimized to one fuel option can provide deteriorated performance and excess emissions if another sustainable option is applied. To investigate the scale of this problem, injection pressure sweeps were performed around the stock, low NOX and low PM engine calibration utilizing split fuel injection. The results showed that FAME and HVO prefer lower injection pressures than diesel fuel, with the benefits of simultaneous reduction of all emission indicators compared to DF. Additionally, reduction of injection pressure from 80 MPa to 60 MPa for biodiesels at low engine load resulted in improved brake thermal efficiency by 1 percentage point, due to reduced parasitic losses in the common rail system.
