CONTROL DEVICE OF IN-CYLINDER FUEL INJECTION TYPE INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To keep lubricant performance and prolong a lubricant life at the maximum.SOLUTION: In an internal combustion engine in which a fuel injection valve directly injecting fuel to a combustion chamber is arranged, when a lubricant dilution ratio is high, a fuel injection time per fuel injection is made shorter than that in a case where the dilution ratio is low. Provided is a control device of an in-cylinder fuel injection type internal combustion engine characterized that an injection number per combustion cycle is increased.
