Title:
内燃機関の燃料噴射制御装置及び燃料噴射制御方法
Document Type and Number:
Japanese Patent JP7100483
Kind Code:
B2
Abstract:
A fuel injection control device and a fuel injection control method according to the present invention are applied to an internal combustion engine including a blow-by gas recirculation device configured to return blow-by gas into an intake passage. According to the present invention, a dilution ratio which indicates how much lubricating oil of the internal combustion engine is diluted with unburned fuel mixed in the lubricating oil is determined. Then, fuel reduction control for reducing fuel supply to the internal combustion engine by a subtractive fuel amount depending on the dilution ratio is performed in a period from an onset of start-up of the internal combustion engine to when a number of combustion cycles accumulated from the onset of the engine start-up reaches a threshold value.
