FIELD: mechanical engineering; automobile internal combustion engines. SUBSTANCE: system has air cleaner 1, mixed air pipe 2, heated and cold air branch pipes 3 and 4, respectively which have open ends 5 and 6, air flow temperature control member and device to suppress acoustic resonances and low frequency pulsation of gases in members of engine intake manifold. Pipe 2 and branch pipes 3 and 4 are of equal length L. Temperature control member is made of sound reflecting material and mounted on open ends of 5 and 6 of branch pipes 3 and 4. Gates 7 and 8 operate in OPEN or CLOSED positions. Device to suppress acoustic resonances and low frequency pulsations of gas is made in form of quarter wave resonator formed by one of branch pipes, 3 or 4 in which gate 7 or 8 is in CLOSED position. EFFECT: improved acoustic and other operating characteristics of automobiles. 2 cl, 5 dwg
