FUEL INJECTION DEVICE FOR GASOLINE CYLINDER DIRECT INJECTION INTERNAL COMBUSTION ENGINE FOR OPTIMUM INJECTION TO INTAKE PIPE, AND METHOD FOR OPERATING FUEL INJECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To restrain production of sediments and furthermore remove the produced sediments in some cases by temporarily injecting fuel into an intake pipe 7 using a second injection valve 15. SOLUTION: This fuel injection device for a gasoline cylinder direct injection internal combustion engine has a high pressure fuel pump, a control unit 18, and a respective first injection valve 9 for every cylinder 3. This device is also equipped with at least one second injection valve 15 so that the fuel can be injected to the intake pipe 7 by the second injection valve 15.
