Abstract
A combustion control apparatus for an internal combustion engine includes a spark plug for performing spark ignition of an air-fuel mixture in the combustion chamber, a plurality of coil pairs for generating spark discharge in the spark plug, and a fuel injection valve capable of injecting atomized fuel. Atomized fuel is injected into the intake passage, and a homogeneous lean air-fuel mixture is formed in the combustion chamber. The air-fuel ratio of the air-fuel mixture in the combustion chamber is controlled to be leaner than a predetermined lean air-fuel ratio. A spark discharge start timing and a spark discharge continuation time period are controlled using the plurality of coil pairs. The spark discharge start timing is set to a timing advanced from the spark discharge start timing for igniting a stratified lean mixture, such that the air-fuel ratio in the vicinity of the spark plug is relatively small.
