Abstract

PURPOSE:To enhance the reliability of controller as well as simplify its structure to a system in which contents to be memorized in table are converted to time values and when the values come to coincide with elapsed time since the time of reference angle signal generation, an ignition signal is sent out. CONSTITUTION:The reference angle sensor 1 sends out a reference angle signal every fixed angles of crank shaft and the intake negative pressure sensor 2 detects the intake negative pressure of engine. The arithmetic circuit 3 calculates the revolution number of engine from the reference angle signal b and then sends out read-out signals corresponding to the calculated value and intake negative pressure value given by the intake negative pressure sensor 2 to the table 4 into which optimum admission angles corresponding to each revolution number and each intake negative pressure which are converted into time values are put in advance. The pulse number read out on the table 4 is memorized in the registor 6. The registor 6 integrates clock pulse from the clock oscillator 5 and when the value coincides with memorized value, sends out the ignition signal d.
