FIELD: transport engineering; construction, road building, logging vehicles and automobiles intended for operation at below zero temperatures. SUBSTANCE: phase transfer heat accumulator is used as heat source in starting preheater system with binary salt mixture of lithium and potassium nitrates being used as heat accumulating substance. Heat accumulator has reservoir for keeping heat carrying agent with system of filling in and draining into engine which makes is possible to use water as heat carrying agent. Starting preheater system of thermosyphon type has no devices requiring supply from storage battery and is designed for operation at ambient temperatures down to minus 40 C. EFFECT: enlarged operating capabilities. 2 dwg
