The diesel engines is used in many industrial applications in addition to that in cars. In this type of engine the fuel-air mixture will burn behind the piston inside the cylinder and will produce high temperature. Developing diesel engines to be more efficient, less fuel consumption, low gas emissions, and high performance that has been pursued for more than two decades. Increased combustion temperature can enhance engine power and efficiency while lowering specific fuel consumption and CO emission rates. Ceramic thermal barrier coatings have been identified as the most promising method for achieving these goals. Due to the abundance of materials and technologies, it is necessary to understand the best material suitable for depositing and the techniques required to complete the process. Many researchers have studied a wide range of materials like ZrO2, Al2O3, mullite, YSZ, and forsterite to develop suitable systems that use thermal barrier coatings. Additionally, many techniques such as EB-PVD and ASP have been developed to meet the requirements of these systems. This paper will examine the materials and technologies that can be used to improve internal diesel engine performance.
