Abstract

The invention relates to a device and method for controlling start of a compression self-ignition engine. According to the device and method for controlling start of a compression self-ignition engine, a restart controller (52) of an electronic control unit (50) determines whether the restart condition of the engine is satisfied based on the various sensor values (Step S21), the piston stop position of the compression-stroke-in-stop cylinder is confirmed to be within the reference stop position range R (Step S22: YES), the fuel is injected in the compression-stroke-in-stop cylinder, the controller controls the fuel injector to perform a pre-injection before a main injection and increase a total injection amount of the fuel for the pre-injection as the stop position of the compression-stroke-in-stop cylinder piston is further on a top dead center side (Step S23)

Description

technical field

[0001] The present invention relates to a compression auto-ignition engine installed on a compression auto-ignition engine that combusts fuel injected into a cylinder by auto-ignition, automatically stops the above-mentioned engine when a predetermined automatic stop condition is satisfied, and then uses a starter motor when a predetermined restart condition is satisfied A start control device for a compression auto-ignition engine that restarts the above-mentioned engine by injecting fuel into a compression stroke cylinder that is in the compression stroke when the engine is stopped by applying rotational force to the engine. Background technique

[0002] The thermal efficiency of a compression auto-ignition engine represented by a diesel engine is generally better than a spark-ignition engine like a gasoline engine, and the emitted CO 2 The amount is also small, so it has been widely used as a vehicle engine in recent years.

[0003] For a compression auto...
