The optimization of the thermal state of the cylinder sleeve in the study involves equalizing the temperature of its working surface in the area of operation of the compression rings to a certain level at which the optimum viscosity of the engine oil is achieved and the mechanical losses in the conjugation of the piston-sleeve are reduced. The use of aluminum alloys with a higher thermal conductivity than the materials of most serial sleeves - pig iron MH is considered as the main means of temperature equalization. The wear resistance of the working surface of the sleeve is ensured by the corundum coating. The results of the nonmotor experiment for the determination of the heat-insulating effect of the coating, the results of calculations of the thermal state for variants of aluminum alloy casings with corundum coating are given. Calculations are performed using a mathematical model based on the finite element method. It is shown that the use of an aluminum alloy AL19 with high thermal conductivity in the working temperature range allows for a significant reduction of the temperature in this most thermally stressed zone (from 278 to 214 ° C) due to more intense heat removal from the upper belt of the sleeve. The decrease of temperatures by 30-50 ° C is also observed in the adjacent zones of the working surface. At the same time, the insulating effect of the corundum layer is insignificant and evaluated within 2-5 ° C. Therefore, such a layer with a thickness of 0,2-0,3 mm is considered only as a means of protecting the working surface from wear. In addition, the results of the study show that the friction zone of the compression rings still remains supercooled (158-102°C), especially near the lower seating belt. Solving the problem can be applied to the outer surface of the sleeves of enamel or other coatings that have a significantly lower thermal conductivity.

The rise in prices for liquid petroleum fuels, observed over the past decades, as well as the tightening of environmental regulations on the content of marine engines of toxic substances and greenhouse gases in the exhaust gases, have made the use of natural and petroleum gases an attractive alternative to traditional motor fuels. And this is despite the additional technical difficulties associated with their use. Given that more than 70% of the main engines are in the merchant fleet, these are low-speed two-stroke engines, the solution of the problems associated with transferring them to gas fuel is particularly relevant at the present time. The problem of translation is aggravated by the fact that, due to the peculiarities of the organization of the workflow, in two-stroke engines of this class only internal mixing is possible, which is carried out during the compression stroke. The latter circumstance required the development of fundamentally different approaches to solving the problem in comparison with those traditionally used on four-stroke high and medium-speed engines. A certain limitation complicating the solution to the problem of organizing a working process on gas fuels is the need to keep the engine able to work on traditional liquid fuels in the entire range of load-speed modes. Currently, MAN and WinGD share leading positions in the field of dual-fuel low-speed engines, the first of which developed a line of engines with gas fuel supply to the engine working space under high pressure at the end of a compression stroke, and the second under low pressure at the beginning of a compression stroke . Each of these methods has both certain advantages and significant drawbacks. The low-pressure fuel supply greatly simplifies the design of the fuel system of the engine and reduces the requirements for ensuring its safety during operation, however, these engines are prone to detonation combustion, which significantly reduces their use, especially in near-nominal conditions. This article is devoted to the search and justification of technical solutions to minimize this drawback while maintaining the inherent advantages of the method.

The analysis of the features and methods of modernization of serial internal combustion engines was carried out in order to increase the output parameters. With specific examples, it is shown that the desire of engine manufacturers to improve performance while minimizing costs often leads to an unreasonably high risk of uncontrolled changes in the loads on parts, when after upgrading the quality and reliability of products deteriorates. At the same time, the most dangerous variants of modernization should be considered the so-called scaling, which produces a slight increase in output parameters while maintaining the same structure and geometry of the main parts, which is usually done without necessary research and testing or, at least, without modeling loads on parts the purpose of determining the critical sections and their possible amplification. Examples of modernization of engines by increasing the size of parts and increasing the boost pressure, as well as its consequences, causing various damage and destruction of the main parts, which is associated with exceeding the permissible level of loads, are done. In order to prevent a reduction in the reliability of upgraded production engines with the exclusion of unnecessarily high costs, an assessment was made of possible ways of modernization. A general approach to modeling the loads on the main parts of the upgraded serial ICE is proposed, the main results of modeling the stress-strain state of the piston, piston pin and connecting rod are given. Data were obtained to identify dangerous sections in which locally high stresses are observed, which increase the risk of fatigue failure of parts with increasing loads. Based on the results obtained, recommendations were given on the practical application of a computational experiment when modernization of serial ICEs
