Abstract
The present device for limiting the running speed is associated with an electronic ignition device comprising at least one energy storage member (21) which is normally charged so as to store at least a nominal quantity of energy, means (22, 23) for applying the said energy to an ignition coponent and electronic means (14, 25, 26) for generating the charging time of the energy storage member. The device itself for limiting the running speed comprises means (10, 13) for detecting the maximum permitted running speed of the engine and an electronic circuit (50) which is put, by the detecting means, into a first inactive state when the engine running speed is less than the maximum running speed and into a second active state in which it controls the generation by the said means (14, 25, 26) of a charging time of angle of the energy storage member at a non-zero value which is significantly less than the time or angle which is necessary for the production of the said nominal quantity of energy when the engine running speed is equal or above the maximum permitted running speed.
