ディーゼルエンジンの始動装置及び始動方法

Document Type and Number:

Japanese Patent JP5924066

Kind Code:

B2

Abstract:

The present invention pertains to a diesel engine starting device, and achieves stable combustion in a short time when the diesel engine is restarted after stoppage of idling. The diesel engine starting device includes injectors (11) that inject fuel in respective cylinders, and glow plugs (13) that generate heat upon receiving electricity to increase the temperature of the respective cylinders. The diesel engine starting device also includes a starter motor (40) that is driven when the engine starts, and an electronic control unit (ECU) (70) that controls the injectors (11), the glow plugs (13), and the starter motor (40). The ECU (70) stops the piston of the cylinder #1 at the bottom dead center of the compression stroke when the idling is stopped, and starts the electricity feeding to the glow plug (13). When an automatic stop condition is no longer met and the engine should be restarted, the ECU (70) drives the starter motor (40), and causes the injector (11) to inject fine amounts of fuel in the cylinder #1 in multiple injection stages. The ECU also causes the injector (11) to inject a small amount of fuel for ignition immediately before the piston of the cylinder #1 reaches the top dead center.
