Abstract
In an internal combustion engine having an air intake passage containing a throttle valve, and provided with passages to the outside from points upstream and downstream of the throttle valve, an auxiliary air regulator comprising a mounting block within which is formed a bypass passage, one end of which is matably connected with a passage in said air intake passage upstream of the throttle valve, and the other end of which is matably connected with a passage in said air intake passage downstream of the throttle valve. A movable shutter means is disposed within said bypass passage so as to control the effective cross-sectional area of said bypass passage. A bimetallic coil is enclosed within an air tight chamber annd being selectively heated. Engaging means connects the outer end of said bimetallic coil with said shutter means so that a movement of the bimetallic coil in response to a temperature change is transmitted mechanically to the shutter means. The auxiliary air regulator is directly attached to the air intake passage.
