摘要： An ignition system for internal combustion engines wherein an ignition timing computer circuit starts the computation of an ignition timing in response to the detection of a predetermined angular position of the crankshaft of an internal combustion engine by an angular position detector, and an ignition device ignites the engine according to the computed ignition timing. A pressure detector detects variations of the pressure in the cylinders caused by the ignition of the engine and a retard-advance detector determines whether the angular position of the engine crankshaft corresponding to the maximum cylinder pressure agrees with the desired angular position. This retard-advance detector compensates the computation of ignition timing in the ignition timing computer circuit in accordance with its determination. In this way, the ignition timing of the engine is feedback controlled in such a manner that the pressure in the individual cylinders reaches a maximum value at the desired angular position of the crankshaft.

摘要： A spark plug comprises a center electrode fixed to a leg portion which is exposed into the combustion chamber of an engine and comprises a ground electrode which is bent so that its end opposes the forward end of the center electrode whereby discharge is produced between the ground electrode and the center electrode. The ground electrode includes a discharging surface not opposing a first side end portion of the center electrode which is near the bent portion, but opposing a second side end portion of the center electrode which is remote from the bent portion of the ground electrode. The discharging surface of the ground electrode may be provided by forming a projection or groove at the opposing end of the ground electrode.
