ABSTRACT:
This discloses an ignition-timing adjusting system for internal combustion engines, which realizes an advance of the ignition-timing relating to the temperature of an engine. This system comprises vacuum advance means responsive to a vacuum produced by the vacuum in the intake tube of the engine for advancing the ignition timing of the engine, and means for controlling the level of said vacuum produced by said intake-tube vacuum with relation to the temperature of the engine. When the engine is cold, the ignition-timing is advanced under control of said vacuum-level controlling means to the proper position for operation of the cold engine.
