FIELD: mechanical engineering; internal combustion engines; starting with heating of flowing medium. SUBSTANCE: electric starting preheater has housing 2, whose liquid space 3 is connected to engine cooling system through supply channel 10 with check valve 28 and outlet channel 14, liquid space cover 8 and electric heating element 4 installed in space. Supply channel made in body of liquid space cover 8 has two sections, axis of first section being parallel to end face surface of cover. Sectional cover consists of interconnected detachable inner and outer covers, 17 and 18, respectively, and spacer 19 placed in between. Second section of supply channel is made in inner cover. First section of supply channel is made partially in spacer and is enclosed partially between end face walls of inner and outer covers pointed to each other. Owing to adopted orientation of supply channel and sectional design of liquid space cover provided are: maximum possible compactness of electric starting preheater and convenience of its arrangement in limited underhood space, both when electric starting preheater is used as self-contained device or when installed on vehicle as higher power unit consisting of two electric starting preheaters of same type-size. EFFECT: maximum compactness, convenience in use. 2 cl, 3 dwg
