Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2013/030926
Kind Code:
A1
Abstract:
When an alcohol mixed fuel is supplied to an internal combustion engine, the magnitude of the alcohol concentration is determined, and the magnitude of a cooling water temperature is determined on the basis of said determination. When the alcohol concentration is high and the cooling water temperature is low, the generation of aldehydes, which are alcohol oxides contained in unburned alcohol mixed fuel, is promoted, and the aldehydes generated by opening an intake valve in the expansion stroke of the internal combustion engine are trapped in an intake passage.
