Abstract
PURPOSE: To reduce a level of vibration and noise in an engine at is low loaded operation, by synchronously actuating an intake air heating device provided in an intake passage with closing operation of an air intake shutter.
CONSTITUTION: A bypass passage 15 having a heating surface 14 its provided in one side of an intake passage 2 of an engine 1, then the heating surface 14 is heated by an exhaust passage 3. A selector valve 16 is provided in an inlet to the bypass passage 15 movably arranged between the actual line position to close the passage 15 and open the main passage 2 and the broken line position to open the passage 15. Further the selector valve 16 is operated by a vacuum actuator 17, and the actuator 17 is connected to a negative pressure take-off port 19 in the downstream of a shutter 5 through a vacuum passage 18. When the shutter 5 is closed to generate negative pressure in its downstream, the valve 16 is moved to the broken line position, and intake air is preheated and guided from the passage 15 to a combustion chamber, then a state of combustion is improved thus an intake air throttling amount by the shutter 5 can be increased.
