Starting device and control method thereof for direct-injection internal combustion engine

摘要

A starting device for a direct-injection internal combustion engine (1) with which starting can be completed swiftly and trouble caused by self-ignition and sudden combustion are prevented by normal spark-ignition being carried out surely on starting. The starting device has compression stroke cylinder identifying means for identifying a cylinder whose piston is in its compression stroke while the internal combustion engine is stopped; start request determining means for determining whether there is an engine start request; and start control means for, when it is determined by the start request determining means that there is an engine start request, injecting fuel into the compression stroke cylinder identified by the compression stroke cylinder identifying means.
