摘要:
Provided with a control device for an in-cylinder injection type internal combustion engine that reduces an amount of fuel attaching to and remaining on a piston crown surface and a cylinder bore wall surface so as to suppress an increase in the number of exhaust particles of PM when fuel injection is performed a plurality of times in one burning cycle. In divided multi-stage injection in which the fuel to be injected in one burning cycle is divided into a plurality of times, an injection amount rate of injection at an early timing among injections divided into the plurality of times is set according to a fuel cut continuous time at a timing when the fuel injection is resumed from a fuel cut state.
