FIELD: mechanical engineering; lubrication system of internal combustion engines. SUBSTANCE: engine has timing gear, crank-and-connecting rod mechanism, cooling, fuel, ignition and lubrication systems. Lubrication system has oil pump, oil sump, oil pressure control transmitter and bottle in form of Dewar flask accommodating hermetically sealed capsules containing heat accumulating compound changing its aggregate state within oil operating temperature range of lubrication system. Bottle is hydraulically connected at bottom side by one channel with oil main line, and by other channel, with oil sump space. EFFECT: reduced wear of friction parts at engine starting, reduced vulnerability of engine at below zero ambient temperatures. 1 dwg
