Title:
Engine ignition timing controller
Document Type and Number:
Japanese Patent JP6340630
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To effectively restrict the knocking generation without reducing the fuel consumption performance.SOLUTION: An ignition timing control device of an engine 100 comprises: an engine body 20; and an ignition control part 54. When the operational state of the engine body is in the high load region, the ignition control part sets the advance angle limit of the ignition timing to the same or retarded side with respect to a case where the operation state of the engine body is in a low middle load region where the load is lower than the high load region. When the operational state of the engine body is in the high rotation region of the high load region, the ignition control part sets the advance angle limit of the ignition timing to the advanced side with respect to a case where the operation state of the engine body is in a region where the rotation speed is lower than the high rotation region of the high load region.SELECTED DRAWING: Figure 4
