Abstract
Disclosed is a control apparatus for a turbocharged diesel engine. The control apparatus comprises an engine start controller (10) operable, when an engine restart condition associated with a demand for vehicle start is satisfied, to execute a split-injection control to perform a main injection for injecting fuel at a timing around a top dead center of a compression stroke, and a post injection for injecting fuel in an expansion stroke following the main injection, during the engine restart control, and, when an engine restart condition nonassociated with the demand for vehicle start is satisfied, to execute the engine restart control to perform only the main injection without executing the split-injection control. This makes it possible to optimize the engine restart control to be execute in response to satisfaction of the engine restart condition, depending on the presence or absence of the demand for vehicle start.
