アイドル回転数調整装置。 An internal combustion engine comprising: a bypass valve disposed in a bypass passage that bypasses a throttle valve disposed in an intake passage; and an idle adjustment means for manually adjusting the amount of intake air when the throttle valve and bypass valve are fully closed. When adjusting the idle speed of the engine, the bypass valve is opened and closed according to the deviation between the target idle speed and the actual engine speed, and
The ignition timing is electronically adjusted according to the operating state of the engine to control the engine speed near the target idle speed, and a signal generating means for generating a predetermined signal by a manual switching operation is provided, and the signal When the predetermined signal is generated from the generating means, atmospheric pressure is detected in an idle rotation speed adjusting device that fixes the actuation amount of the bypass valve and the ignition timing to predetermined values, respectively, to enable idle adjustment by the idle adjusting means. pressure detection means for detecting intake air temperature; and temperature detection means for detecting intake air temperature; An idle speed adjustment device for an internal combustion engine, characterized in that the device corrects the idle speed based on the intake air temperature detected by the means.
