“…Another approach to enhance efficiency is using ‘thermal barrier coatings' to minimize heat losses in combustion engines, ensuring higher operating temperatures in the combustion chamber. Available ceramic materials for coating barriers used with a thickness of 100 μm to 1 mm on the piston crown and cylinder head can reduce the brake-specific fuel consumption between 1.7 % and 5 % [ 49 ]. Coating the cylinder liner with the piston crown and the cylinder head can reduce brake-specific fuel consumption by up to 8.5 % [ 50 ].…”

“…Critical equipment such as engine cylinders and combustors [2][3][4] frequently operate in prolonged high-temperature environment. TBCs need to be applied to the internal surface of cylinder bodies, pipelines and other components to enhance operating temperature and performance [5][6][7]. One of the most common preparation methods for TBCs is atmospheric plasma spray (APS) [8].…”

Thermal barrier coatings (TBCs) play a crucial role in enhancing the operating temperature of key equipment. However, when TBCs are sprayed on the internal surface of these components, there are issues related to the imperfect internal diameter atmospheric plasma spray (ID-APS) process and the unsatisfactory performance of TBCs in internal holes. Yttria-stabilized zirconia (YSZ), YSZ + Gadolinium zirconate (GZ) and YSZ + tantalate (RETaO4) TBCs were prepared using the SM F210 ID-APS gun. The thermal shock and particle erosion resistance of the coatings were compared, and the relationship between the structure and properties was investigated. The results show that the hardness, fracture toughness and erosion resistance of the three coatings are the largest in the YSZ coating and the smallest in the GZ coating. YSZ coating also has the best thermal shock resistance. These research findings have important guiding significance for the improvement of the ID-APS process.

“…Most of the recent studies on internal combustion engines focus on reducing fuel consumption values [1][2][3], reducing exhaust emissions [4][5][6] and improving combustion efficiency by replacing engine materials [7,8]. In the studies conducted at this stage, it is generally stated that the combustion efficiency in the cylinder is increased by coating the piston and valve surfaces with materials with low thermal conductivity with different methods and that there are decreases in exhaust emissions [9].…”

In this study, the thermal analysis of an aluminum piston coated with MgOZrO2 to create a thermal barrier with the COMSOL multiphysics program and the changes in exhaust gas temperature, fuel consumption, and engine torque values obtained as a result of engine test experiments were examined. For this purpose, the MgOZrO2 coated and uncoated piston engine was started with biodiesel and 5% water + 15% ethanol doped biodiesel fuel at engine speeds of 1000 rpm, 1500 rpm, 2000 rpm, and 2500 rpm. In the thermal analysis results obtained in the COMSOL, it was found that the temperature values increased in the upper regions of the coated pistons. Likewise, in engine experiments, increased exhaust gas temperature and engine torque showed a tendency to decrease fuel consumption values. It has been observed that the data obtained in the analysis in the COMSOL program are in parallel with the results of the engine experiments.
