Title:
エンジンの始動制御装置
Document Type and Number:
Japanese Patent JP6575579
Kind Code:
B2
Abstract:
To increase the opportunity to restart an engine automatically by performing fuel injection and ignition for a cylinder being under an expansion stroke.SOLUTION: For a cylinder being under an expansion stroke, fuel injection is performed and also ignition is performed at predetermined ignition timing, thereby automatically restarting an engine. According to difference of a stop position of a piston 3 being under the expansion stroke in automatic stop, the predetermined ignition timing is changed. For example, when a piston stop position is near a top dead point in the expansion stroke, the ignition timing is set to advanced SP1, when the piston stop position is near a bottom dead point in the expansion stroke, the ignition timing is set to retarded SP2, and when the piston stop position is at an intermediate position, the ignition timing is set to both of SP1 and SP2.SELECTED DRAWING: Figure 3
