“…Apart from the previously used traditional methods of assessing the parameters of injection and combustion of mixtures of RME with diesel fuel [26][27][28][29], attempts are made to use new phenomena of numerical modelling to develop the impact of fuel properties on the course of mechanism reaction in the combustion chamber [30]. Model studies are also carried out on the impact of the fuel injection pressure on the delay of auto-ignition, the fuel atomization and combustion processes [31]. Research is also carried out on the development of an oxy-fuel flame with the use of a test burner [32][33].…”

The purpose of the study was the research concerning the emissions of limited exhaust gas components of the AVL research engine equipped with common rail injection system, fuelled with different biodiesel blends and diesel fuel as reference. In details, the engine was powered with mixtures of rapeseed methyl esters with diesel fuel in the volumetric ratios of 10:90, 20:80, 30:70, 40:60 and 50:50. The tests were performed at: 1200, 1700 and 2200 rpm and the torque T = 5-35 Nm (step 5 Nm). The analysis of the obtained results showed that the emissions of hydrocarbons from the tested engine fuelled with biodiesel are lower than that of diesel fuel. Carbon monoxide emissions are also lower, except for low rotational speeds and low engine load T = 5-20 Nm. As for nitrogen oxides emissions, it is also lower than that for the diesel fuel, except for high engine loads, in the range above 25 Nm, for each rotation speed of the engine load characteristics. Moreover, in this research it was confirmed that emission of particulate matter is also slightly reduced for the engine fuelled with tested blends.

“…Eight regions were selected to find the most knocking occurring region. The maximum pressure Pmax was calculated for all regions by using filtered pressure for all cases (Ashkezari et al, 2020). From Figure 4, it is clear that knocking is more evident in the regions near cylinder wall than all other regions owing to the presence of methanol-auto-ignition presence.…”

Purpose The purpose of this paper is to find the pressure and the knocking phenomena. To get the pressure values, the butterworth bandpass filter was used and the potential of knocking was found by using peak-to-peak pressure values and also the species concentration. Cooled exhaust gas recirculation was the method used to minimize the knocking occurrence in the engine. Moreover, the effect of premixed methanol and start of engine (SOI) on knocking were also determined. Design/methodology/approach This paper deals with the compression ignition engine to investigate the unfavorable knocking behavior. The tests were carried out with the 3D model of engine fueled with waste cooking oil blended with TiO2. A number of tests were taken to find the pressure variation and the species concentration at eight different locations in the computational model. Findings In doing the tests, the positive intended outcome was achieved. From results, it is clear that the SOI and premixed methanol mitigated the knocking process. Originality/value The species concentration and pressure in the form of filtered signal were proved to be the ideal methods for evaluating the knocking event in the engine.

“…Another source for obtaining fuel is karanja, grown in India, China and Japan. Currently, research on the use of various vegetable and animal esters as additives in diesel fuel is carried out in the form of simulation [5,12,14,24] and experimental tests [3,6,10,12] in order to optimize the parameters of the injection and combustion of exhaust emissions as well as engine performance with the use of the latest numerical modelling methods. However, research on real objects [2, 6, 10, 14, 17, 24, 28, 31] are the major part of the tests.…”

In the global fuel economy, new challenges concerning the use of alternative (vegetable) fuels in the internal combustion engines are starting to arise. The important issue is to meet the new limits on four main pollutant emissions from a diesel engines: CO (carbon monoxide), NO x (nitrogen oxides), HC (hydrocarbons) and PM (particulate matter). The design of a modern engine must be characterized by high efficiency, its dynamics of movement and durability. Dynamic development of plant fuels is forced by the new strategy of the global fight against the global warming. For these reasons, it is necessary to do research concerning the effects of the use of biofuels, including methyl esters, higher fatty acids of rapeseed oil for self-ignition engines. The current tests must concern the engines equipped with the latest Common Rail fuel injection systems. In the publication, the above-mentioned issues have been analyzed, and the results of tests of the basic injection process parameters have been presented. The AVL5402 engine was fueled with mixtures of diesel oil with RME ester of rapeseed oil produced by ORLEN Południe S.A. in Trzebinia. The impact of the RME content in the mixture with diesel fuel (DF) on the injection process parameters such as: initial velocity of the injected fuel, critical speed of secondary fuel breakup, critical droplet diameter, microstructure of the fuel stream, droplet Sauter mean diameter, vertical angle of the fuel stream, have been justified. The impact of the RME content in the mixture with diesel fuel on the above-mentioned parameters has been proved. During the tests, the engine worked on the load characteristics.
