“…5) as stated in the research [7], there is a possibility of synergistic interaction of the nitrON ® package (reducing the speed of kinetic combustion) with the addition of Reduxco ® -DAGAS, Poland (increasing the heat of combustion in the diffusion phase) to simultaneously reduce NO x and PM emissions.…”

“…14), it should be assumed that the more favorable dQ/dα mileage is related to the earlier end of the test fuel burn. TDI engine fueled with test fuel in relation to the base fuel [7] It can be seen from the data in Fig. 15 that the end of the test fuel (with nitrON ® addition) burn is earlier in comparison to the base fuel under high engine loads.…”

“…The earlier end of combustion reduces the heat loss carried out with the exhaust gas, which translates into an increase in thermal efficiency (η t ) for the test fuel. TDI engine powered with the test fuel in relation to the base fuel [7] In fact, the NITROCET50 ® additive in the nitrON ® package reduces the heat release rate (as a result of shortening the auto-ignition delay), but the action of this additive in relation to dQ/dα is selective and does not reduce the average burning rate, but only reduces the maximum kinetic combustion rate. As can be seen from the diagram (Fig.…”

In order to avoid the negative effects of increasing the amount of RME in the fuel, the nitrON® package was used, containing 3 different additives: stabilizing, washing and increasing the cetane number of the fuel. The tests were carried out with the use of the Caterpillar C27 engine of the 6Dg locomotive connected to a water resistor. The hourly engine fuel consumption (FC), NOx concentration and exhaust opacity were measured for 3 points of the F test, in accordance with UIC 624. The concentration of the nitrON® additive in the test fuel was 1500 ppm (v / v). For idling, the reduction in FC value was only 1.5% (in relation to the base fuel), but for a very high engine load and nominal rotational speed, the percentage reduction in FC was as high as 5%. The reduction of NOx concentration for idling (as a result of using nitrON®) was approx. 10%, while for high engine load, the percentage reduction of NOx concentration in the exhaust gas exceeded 15%.

Renewable Fuels for Internal Combustion Engines

2021

View full text Add to dashboard Cite

The continuous need for systematization and open dissemination of knowledge on Renewable Fuels intended for use in Internal Combustion Engines forms the premise of the presented Special Issue titled “Renewable Fuels for Internal Combustion”. Experts in the field were encouraged to share their latest findings in the form of original research papers, case studies, or short reviews. Works targeting all aspects of the value chain were considered necessary, including the following: (liquid and gaseous) fuel production process, upgrading (catalytic and fractional blending), up to end, valorization in combustion engines (conventional and advanced concepts). Finally, techno-economic analyses aiming to valorize the value chain holistically were warmly encouraged to submit papers in this Special Issue of the Energies Journal. In this book, the reader will find successful submissions that present the latest findings from the discussed research field, encapsulated into nine chapters.

Research was conducted on fuels with additives that selectively affect the rate of kinetic (dQk/dα) and diffusion (dQd/dα) combustion in the diesel engine cylinder. In addition to the base fuel (DFB), DFKA fuel with an additive reducing dQk/dα, DFDA fuel with an additive increasing dQd/dα, and DFS fuel with both additives were tested. The main purpose of such dQ/dα course control in the engine cylinder was to simultaneously reduce the emissions of nitrogen oxides (NOx) and particulate matter (PM), and to increase the efficiency of the combustion process. Similar to the course of the dQ/dα, the course of the combustion temperature (Tc(α)) affects the NOx produced and the number of afterburned solid particles; the influence of the fuel additives on the functional curves was analysed. In addition to analysis of the temperature Tc(α) calculated from the indicator diagrams, Tc(α) analysis was conducted using the two-colour method, which allows the analysis of the isotherm distributions locally and temporarily. The two-colour method required prior endoscopic visualisation of the fast-changing processes inside the engine cylinder. Parameters defined by pressure, temperature, heat release rate, and visualisation and thermovision in the engine cylinder (as a function of the crank angle) allowed for an in-depth cause and effect analysis. It was determined why combustion of DFS fuel with both additives produced a synergy resulting in the simultaneous reduction in NOx and PM emissions in the exhaust gas and an increase in combustion efficiency. This publication relates to the field of Mechanical Engineering.
