Abstract
In a process of automatically stopping a diesel engine upon fulfillment of automatic engine stop conditions, an ECU cuts off fuel injection when the engine speed equals a preset first engine speed N. The ECU limits the amount of intake air at the first engine speed Nand, then, increases the amount of intake air at a point in time when the engine speed equals a second engine speed N, at which point a piston in a cylinder which will be on a compression stroke at engine stop is expected to transfer to a last intake stroke, so that the piston in the compression stroke cylinder at engine stop stops at a point within a specified range closer to the bottom dead center than a piston in a cylinder which will be on an expansion stroke at engine stop.
