Abstract: Diesel engines currently remain one of the most sought-after powertrains due to their high fuel efficiency and reliability. However, there is a number of problems associated with heat losses that reduce the overall efficiency of internal combustion engines. This article examines and analyzes the effect of partial thermal insulation of the combustion chamber on the fuel combustion processes and the main characteristics of diesel engines. Based on the analysis performed, it can be concluded that the main advantages of the engines with partial thermal insulation of the combustion chamber are enhancement of the fuel combustion processes, increased fuel efficiency and improved engine start-up properties. However, their widespread use is currently restricted by the high cost and low reliability of thermal insulation materials, as well as insufficient research into their operating processes and the influence of various design, operational and regulatory factors. The author makes conclusions on the prospects for practical application of the recommendations provided and possible directions for further research.

Keywords: thermal insulation, diesel engine, piston, combustion processes, heat losses
