An ignition system of the condensor-discharge type for an internal combustion engine is disclosed which is capable of preventing delay of the ignition position at a high engine speed due to an armature reaction and preventing generation of ignition spark at reverse rotation of the engine without using a signal coil for determining the ignition position.

Ignition system of the condensor-discharge type for internal combustion

A method of controlling an engine speed for an internal combustion engine and an apparatus therefor which are capable of significantly improving transient response characteristics and controlling the engine speed with high accuracy. The method and apparatus are adapted to keep the actual engine speed at a set engine speed by proportional control action and derivative control action wherein a derivative control engine speed range is set about the set engine speed to stop derivative action to allow only proportional action to operate an engine speed adjusting operation unit when the actual engine speed is out of the range.
