Internal combustion engines emit high-temperature, high-pressure, and high-speed exhaust gases, resulting in wasted energy and low thermal efficiency. In order to recover the available residual energy in the exhaust gas, this paper proposes a new topology of the disk-type axial flux stator-excited doubly salient generator (AFSDSG) with partitioned stator suitable for high-temperature and high-speed operation. Based on the analysis of the above generator inductance characteristics, the influence mechanism of three pole-slot structures on the induced electromotive force (IEMF) of the armature winding is clarified, the equivalent magnetic circuit method is used to analyze the influence of different winding arrangements on the no-load performance of the generator, and the principles of pole-slot structure optimization and winding arrangement are summarized. The finite element software is used to model and simulate different configuration. After focusing on the analysis of transient characteristics such as inductance, armature winding IEMF, and air-gap flux, it is concluded that different from the conventional pole-slot structure and winding connection method make that only the overlapping area of the stator and the rotor changes linearly can produce a constant voltage, the winding arrangement of Winding Partition Excitation Span 2 has a high IEMF amplitude value and low harmonic content. Finally, the prototype of a three-phase 12/8-pole was trial manufactured and tested. The consistency of the simulation results and experimental results is verified the innovation and feasibility of the new topology proposed in this paper.

“…The consumption of fuels manufactured from renewable sources was planned and described in "White paper 2011" and DIREC-TIVE (EU) 2018/2001 [15,16]. For decades, blends of fossil fuel with bioethanol have been utilized in spark ignition ICEs and with fatty acid methyl esters in compression ignition ICEs [14,[17][18][19][20][21][22]. Despite the fact that the raw material of biofuels (oil from rapeseed, soy, sunflower, palm, etc.)…”

This research compares the air pollution (CO, CO2, HC, NOx, smoke), energy (brake-specific fuel consumption, thermal efficiency) and noise indicators of a compression ignition engine fueled by first-generation biodiesel (rapeseed methyl ester (RME)) and second-generation biodiesel (hydrogenated vegetable oils (HVO)), or conventional (fossil) diesel fuel blends. The concentration of first- and second-generation biodiesel in two-component blends with diesel fuel was up to 15% and 30% (RME15, RME30, HVO15, and HVO30); for comparison, the three-component blend of diesel fuel, HVO and RME (RME15–HVO15) was considered. The fuels’ physical and chemical properties were tested in a specialized laboratory, and the engine load conditions were ensured by the engine brake stand. Referring to ship power plants with constant-speed engines, detailed research was carried out in one speed mode (n = 2000 rpm). Studies have shown that two-component fuel blends with HVO are superior to conventional diesel fuel and two-component blends with RME in almost all cases. The HVO in fuel blends reduced fuel consumption up to 1.8%, while the thermal efficiency was close to that of fossil diesel fuel. In addition, a reduction in pollutants was observed: CO by ~12.5–25.0%; HC by ~5.0–12.0%; NOx by ~6.5%; smokiness by ~11–18% (two-component blend) and up to ~29% (three-component blend). The CO2 and noise characteristics were close to those of fossil diesel fuel; however, the trend of reduced smoke emission was clearly seen. A fundamental obstacle to the wide use of HVO can be seen, however, which is the price, which is 25–90% (depending on the EU country) higher than the price of conventional (fossil) diesel fuel.

“…YSZ coating is widely used in the leaves of gas turbines, due to its excellent performance, and many researchers have applied the YSZ coating on the diesel engine [9][10][11]. However, compared with the gas turbine, the repeated thermal cycling in a diesel engine makes the YSZ coating more likely to crack, and then accelerates the oxidation of the bond coat, which eventually causes the coating to fail [12].…”

Due to special working conditions, diesel engines often need to run stably for a long time at high power operating conditions. As the core of diesel engine moving parts, the piston needs to be exposed to high temperature for a long time. Based on the problem of excessive piston temperature at the maximum power point of a certain type of diesel engine, this paper discussed the protective effect of using different thicknesses of Mullite thermal barrier coating on the top surface of the piston, by using the method of hardness plug temperature measurement and three-dimensional simulation. When the thickness of the ceramic coating was increased from 0.2 to 0.7 mm, the maximum temperature of the piston seat decreased from 358.6 to 338.9 °C. This showed that the use of Mullite thermal barrier coating could reduce the working temperature of the aluminum alloy piston at the maximum load operating point, and greatly improve the reliability of engine components.
