Abstract
In an ignition timing adjusting device, a breaker plate of a distributor is held in the initial position thereof during idling of the engine and the breaker plate is temporarily moved in the retarding direction in a period of time after starts of the vehicle to positively retard the ignition timing of the engine so as to minimize the NOx emission and thereafter, instantly moved in the advancing direction upon arrival at a cruising speed of the vehicle to quickly advance the ignition timing of the engine so as to ensure good driveability of the vehicle.
