PURPOSE:To prevent the generation of knocking by advancing an angle during low load, and by delaying an angle during high load when engine temperature exceeds a specified value. CONSTITUTION:A CPU45, A/D converter 46, RAM47, ROM48, and RAM49 are connected to each other. When an ignition switch is turned to an ON position, electric power is supplied to elements 45-48. The RAM49 receives power supply independent of the opening and closing of the ignition switch and maintains memory during engine stop. The output of an air flow meter 2, and a water temperature detector 37 are sent to the A/D converter 46. The output of an air fuel ratio sensor 29, a throttle sensor 34, and a car speed sensor 35 are sent to the RAM47. The current to be supplied to a solenoid control valve 26 and a solenoid 42 of an automatic transmission 3 is sent from the ROM48. |
