Patent ID: 6935302

Claim:
An in-cylinder injection type internal combustion engine, comprising: a cylinder block; a cylinder head; a piston; a combustion chamber defined by the cylinder block, the cylinder head, and the piston; a fuel injector for injecting a fuel directly into the combustion chamber, which injects the fuel such that high and low concentration portions of an air-fuel mixture are formed in the combustion chamber during stratified-charge combustion; a first ignitor disposed in a portion of the cylinder head corresponding to a high concentration portion; a second ignitor disposed in a portion of the cylinder head corresponding to a low concentration portion; a load detector for detecting a load required of the in-cylinder injection type internal combustion engine; and an ignition controller which advances an ignition time of the first ignitor relative to an ignition time of the second ignitor when a load detected by the load detector is low during stratified-charge combustion.
