Abstract: FIELD: mechanical engineering. SUBSTANCE: method and assembly are used in manufacture of piston engines. Operating surface is formed by cutting-in of wave pattern into internal surface performed by at least one cutting tool provided with curvilinear cutting edge. Difference of levels between crests and troughs of waves in pattern is at least 0.005 mm. Then crests of waves are removed by plastic compression to at least 0.004 mm of their height with formation of flat areas so that wave trough bottom after compression is on level which is 0.001 mm lower than the above-indicated areas. In longitudinal section internal surface of manufactured line is partially wave. Wave troughs on this surface are separated by flat areas. Cylinder liner for large two-stroke cross-head engine, for example, has operating surface for piston rings on its internal surface. Cylinder liner internal diameter is within 25-100 cm and its length is within 100-400 cm. Use of plastic compression for forming of liner operating surface reduces time required for manufacture of liner. EFFECT: improved quality of liner. 16 cl, 5 dwg, 4 ex

Abstract: FIELD: mechanical engineering; multicylinder diesel engines. SUBSTANCE: invention is aimed at designing compact intake device of engine featuring improved acoustic efficiency. Intake device of internal combustion engine has air cleaner and receiver with separate intake branch pipes connected with cylinder head and communicating with separate cylinders through intake valves. Air cleaner housing has intake port air intake branch pipe and it is made in form of round cylinder limited by bottom and cover. Spaces of receiver and air cleaner are placed in communication by means of air duct. Branched air duct has at least two intake and two outlet branch pipes united by common pipeline. Intake branch pipes are secured on side wall of receiver and on bottom of air cleaner. Axes of intake port of air intake branch pipe and axes of free cuts of intake branch pipes are located in relatively perpendicular planes passing through axis of cylindrical housing. Ratio of distances from centers of free cuts of intake branch pipes to axis of cylindrical housing and ratio of their cross-section areas correspond to following equation a 1 /a 2 /Ф 2 /Ф 1 , where a1, a2 is distance from centers of cuts to axis of cylindrical housing, and Ф 1 ,Ф 2  are areas of cross-sections of cuts. Relationship between distances from centers of free cuts of outlet branch pipes to normal plane of receiver cross-section through its center of gravity and areas of their cross-section can be made to correspond to following equation б 1 /б 2 = S 2 /S 1  where б 1 ,/б 2  - is distance from centers of cuts to said plane, and S1, S2 are areas of cross-sections of cuts. So, summary acoustic work done by pulsations of gas in branched air duct pipes equals zero which precludes excitation of natural oscillations of receiver and air cleaner.
