Title: Device for controlling ignition of internal combustion engine
Inventor: NOROTA KAZUHIKO
IPC: F02P17/12
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To provide an increase in torque variation even if part of an ignition plug group has unusual ignition in an internal combustion engine carrying out ignition at a plurality of points in a plurality of steam cylinders. SOLUTION: If part of ignition plugs belonging to an ignition plug group has unusual ignition ('YES' in S440 or 'NO' in S460), all the ignition plugs of the ignition plug group are inhibited from ignition (S450 or S470). This provides all steam cylinders with ignition by only an ignition plug group under a usual operation. The result falls behind all the steam cylinders in the same combustion state to eliminate a difference in output torque, preventing a variation in torque. If two ignition plug groups have unusual ignition, at least one ignition plug group is not inhibited from ignition ('YES' in S410, 'YES' in S420, or 'YES' in S430 and S460), allowing shunting travel.
