FIELD: mechanical engineering; thermostated intake systems of internal combustion engines. SUBSTANCE: system has air cleaner 1 with branch pipes 3 and 4 and pipe 2 connected to air cleaner chamber and also devices to provide thermostating of intake air and reducing of intake noise. Novelty is that mixed air pipe 2 and heated air branch pipe 4 and cold air branch pipe are of equal length and heated air branch pipe 4, at least, on part of its length is made in the form of cartridge of gas permeable noise absorbing material of high ohmic resistance. Opposite end faces of branch pipe are connected to power source. Rigid plug 5 made of gastight material is fitted in free cut of branch pipe 4. Turnable gate 6 operating in OPEN-CLOSED manner is installed in inlet cut of branch pipe 3. EFFECT: improved economical, pollution preventive and consumers' properties of automobile. 4 cl, 5 dwg |
