Abstract
A starting device for a direct-injection internal combustion engine by which starting can be completed swiftly, and trouble caused by self-ignition and sudden combustion by carrying out a normal spark-ignition can be prevented surely upon starting. The starting device has compression stroke cylinder identifying unit for identifying a cylinder whose piston is in its compression stroke while the internal combustion engine is stopped; start request determining unit for determining whether there is an engine start request; and start control unit for, when it is determined by the start request determining unit that there is an engine start request, injecting fuel into the compression stroke cylinder identified by the compression stroke cylinder identifying unit.
