Abstract
A start control device of a compression self-ignition engine is provided. The device includes: a determining module for determining whether a piston of a compression-stroke-in-stop cylinder that is stopped on a compression stroke according to an automatic stop is within a specific range set on a bottom dead center side of a predetermined reference stop position; an injection control module for controlling each fuel injection valve to inject fuel into the compression-stroke-in-stop cylinder first after the piston of the compression-stroke-in-stop cylinder is determined to be stopped within the specific range and the engine restart condition is satisfied; and an in-cylinder pressure estimating module for estimating an in-cylinder pressure of the compression-stroke-in-stop cylinder at a first top dead center on the compression stroke in the restart, where the piston of the compression-stroke-in-stop cylinder reaches after the restart starts.
