PROCEDURE AND SYSTEMS FOR AUTOMATIC ADJUSTMENT OF THE IGNITION OF A MOTOR WITH CONTROLLED IGNITION

摘要

The apparatus comprises a detector 20 for detecting the position of the engine crankshaft, an accelerometer 18 for producing a signal representing the acceleration of the cylinder head, the signal being integrated by an integrator 45 and supplied to a zero valve detector in the form of an inverter 50, and means for adjusting the ignition timing in dependence on the crankshaft position at which the zero value of the integrated signal is detected. The signals from the sensors 18, 20 are supplied to a circuit 23 which adjusts the ignition timing so that the maximum pressure in the engine cylinders occurs at a preselected position of the crankshaft.
