FUEL INJECTION SYSTEM OF INTERNAL COMBUSTION ENGINE

Title:

FUEL INJECTION SYSTEM OF INTERNAL COMBUSTION ENGINE

Document Type and Number:

Japanese Patent JP2013104329

Kind Code:

A

Abstract:

To reduce adverse effect on an internal combustion engine due to fuel adhesion to a bore when a needle of a fuel injection valve is lifted intermediately.

A fuel injection system controls a lift position of the needle in an injection valve body, on the basis of an operation state of an internal combustion engine, so as to locate the needle in a full-open position where a fuel injection hole is fully opened or any intermediate position between the full-close position where the fuel injection hole is fully closed and the full-open position. When an engine temperature of the internal combustion engine is predetermined temperature or lower, a lift control means prohibits the needle from being lifted in the intermediate position.
