Filed: 1982-01-29
Abstract: PURPOSE:To eliminate the need for an external circuit by an arrangement wherein the change-over between the ignition by a plug 1 and that by a plug 2 is effected by interrupting it into a digital computer. CONSTITUTION:The timing when electric current is allowed to flow through an ignition coil is computed by a CPU, and it is easy to find the angle at which electric current does not flow through the coil. Therefore, the angle at which electric current does not flow through the coil is detected and interruption to CPU is made in accordance with the signal representative of the angle. Load Tp is detected at step 4 and a decision for ignition by plug 1 is made at step 6. If it is decided to make ignition by plug 1, the ignition by the latter is set to I/O (input/output) unit at step 8. If it is not decided to perform ignition by plug 1, ignition by plug 2 is set at step 10. This arrangement eliminates the need for an external circuit.
