Title:
FUEL INJECTION CONTROL DEVICE OF SPARK IGNITION TYPE INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2011153589
Kind Code:
A
Abstract:

To establish a knock control method capable of using for a spark ignition type internal combustion engine having the form of using residual gas with a high compression ratio, high super charging and a high temperature, to provide a fuel injection control device capable of practicing the knock control method, and to suppress fuel consumption while suppressing the generation of knocking.

In the fuel injection control device of the spark ignition type internal combustion engine injecting and supplying two kinds of fuels, the combination of the two kinds of fuels is in a form that the ignition lag times of respective fuels with respect to temperature are reversed at a predetermined boundary temperature, a cylinder temperature calculating means finding the cylinder temperature of the spark ignition type internal combustion engine by detection or estimation is provided, and a control means controls the injection ratio between two kinds of fuels based on a predetermined temperature corresponding to the boundary temperature at which the ignition lag times of two fuels are reversed and a cylinder temperature found by the cylinder temperature calculating means.
