ABSTRACT:
A HC emission controlling apparatus for use in an automobile is equipped with a catalytic type emission disposal converter (system) as an anti-pollution measure, having a deceleration emission controlling device such as a dash pot engageable with the throttle valve lever and connected to a vacuum control device. The apparatus includes a deceleration emission controlling device connected through a vacuum-transmitted valve to the vacuum controlling device, the vacuum controlling device being provided with a change-over valve which is adapted to be actuated by a temperature-sensitive actuating member. The change-over valve brings the vacuum-transmitted valve into communication with the atmosphere and with a vacuum source, respectively, before and after the warming up of the engine.
