“…Point. Sekar and Kamo [17] developed a passenger car equipped with insulated diesel engine, which improved by 12% compared with the general diesel engine. Prasad and others use thermal insulation on the top of the piston, that is, partially stabilized zirconia (PSZ), and tests show that the loss of heat loss by the piston is as high as 19% by the piston.…”

The study of diesel cooling and heat transfer can improve thermal efficiency and reduce exhaust emissions. The research on the heat transfer characteristics of diesel engine block, the influence of the cooling medium control parameters on the heat transfer characteristics of the cooling system and environmental boundary conditions on the heat transfer characteristics of the diesel engine are elaborated, which as the breakthrough point of the research on the cooling heat transfer of diesel engine. The further development direction is discussed. It is pointed out that the research on the content of the best nanoparticles in the nanofluids, the durability test of the low heat rejection (LHR) diesel engine and the intelligent integrated control of the cooling system of the diesel engine at plateau are the key points of the research on the cooling and heat transfer of the diesel engine in the future.

“…A mixture of paraffin wax, polypropylene, linear low-density polyethylene, and stearic acid were used for the binder. The multicomponent system has a density of 0.873 g/cm 3 . The two powders were mixed using an 80/20 vol.% mullite-to-ceria stabilized zirconia ratio via wet ball milling for 24 h in DI water, ammonia, and a dispersant (Darvan 821A, R.T. Vanderbilt Company, Inc.).…”

“…For example, an increase in efficiency of greater than 10% has been previously reported by coating various engine components with ceramics. [1][2][3] However, the requirement of complex-shaped, precision parts for these applications is a major barrier in taking advantage of enhanced properties provided by ceramics. The high hardness of the ceramics makes machining the complex parts difficult and expensive, thus, minimizing the available manufacturing options to produce the parts economically.…”

Powder injection molding (PIM) of ceria-stabilized, zirconia-toughened mullite composites were investigated in the present article with the goal of obtaining performance enhancement in complex geometries for energy and transportation applications. A powder-polymer mixture (feedstock) was developed and characterized to determine its suitability for fabricating complex components using the PIM process. Test specimens were injection molded and subsequently debound and sintered. The sintered properties indicated suitable properties for engine component applications used in unmanned aerial vehicles (UAVs). The measured feedstock properties were used in computer simulations to assess the mold-filling behavior for a miniature turbine stator. The results from the measurements of rheological and thermal properties of the feedstock combined with the sintered properties of the ceria-stabilized, zirconia-toughened mullite strongly indicate the potential for enhancing the performance of complex geometries used in demanding operating conditions in UAV engines.

“…A major breakthrough in diesel engine technology has been achieved by the pioneering work done by Kamo and Bryzik, since the end of the 1970s, as the first persons in introducing TBC system for engines. 4,5 Kamo and Bryzik used thermally insulating materials such as silicon nitride for insulating different surfaces of the combustion chamber. The application of thermal barrier coatings (TBC) in thermal engines has been widely explored as a way to reduce the heat rejected in the combustion chamber [6][7][8][9][10][11] in order to improve engine efficiency and reduce NO x emissions.…”

As well as new advances in the after-treatment systems are required to achieve the new pollutant emission requirements, new designs of the exhaust line can be considered in order to increase the engine efficiency and the after-treatment effectiveness. In the present work, a one-dimensional gas dynamic model has been used to carry out a simulation study comparing several exhaust insulation solutions. This solutions include the insulation of the exhaust ports, the exhaust manifold, the internal surface of the turbine volute, the turbine external housing, as well as different combinations of these solutions. A transient analysis has been done in order to evaluate the increment in the exhaust gases temperature, fuel economy and pollutant emission levels over the WLTC (Worldwide harmonized Light vehicles Test Cycle) at three different temperature conditions. As a conclusion, a 12% increment in the turbine outlet gas enthalpy can be achieved by insulating both the exhausts ports and the exhaust manifold. Moreover, more than 30% less pollutant emissions are released to the environment with this setup.
