Document Type and Number:
WIPO Patent Application WO/2013/030924
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 alcohol contained in the alcohol mixed fuel that is unburned after a main injection, and aldehydes, which are alcohol oxides contained in the alcohol mixed fuel that is unburned after a post injection, are promoted, and the aldehydes generated by opening an intake valve in the exhaust stroke of the internal combustion engine are trapped in an intake passage.
