Abstract
A combustion control device and a method for a direct injection engine are disclosed wherein, when the engine is operating in the partial load range, the valve opening/closing mode of an intake valve and/or an exhaust valve is controlled so that exhaust gases remain in a combustion chamber; and control is performed such that fuel is injected from a fuel injection valve into residual exhaust gases at least once during the time period from the latter half of an exhaust stroke to the first half of an intake stroke in one combustion cycle, and that an air-fuel mixture is ignited in the latter half of a compression stroke thereafter.
