Patent ID: 7043350

Claim:
A fuel injection control apparatus for an internal combustion engine comprising: a fuel injection valve disposed on an intake port on the upstream side of an intake valve of said internal combustion engine; a detector that detects operating conditions of said internal combustion engine; a spray condition changing apparatus for changing a spray condition of said fuel injection valve; and a control unit that controls said spray condition changing apparatus based on said operating conditions, wherein said detector detects an engine temperature and an engine load as the operating conditions of said internal combustion engine, wherein said spray condition changing apparatus is an apparatus for changing an angle of spray of said fuel injection valve, and wherein said control unit: controls said spray condition changing apparatus to narrow the angle of spray, when said engine temperature is equal to or less than a predetermined temperature; controls said spray condition changing apparatus to widen the angle of spray, when said engine temperature exceeds said predetermined temperature and also said engine load is equal to or less than a predetermined load; and controls said spray condition changing apparatus to narrow the angle of spray, when said engine temperature exceeds said predetermined temperature and also said engine load exceeds said predetermined load.
