CONTOL DEVICE FOR INTERNAL COMBUSTION ENGINE

Title:

CONTOL DEVICE FOR INTERNAL COMBUSTION ENGINE

Document Type and Number:

WIPO Patent Application WO/2013/054407

Kind Code:

A1

Abstract:

This electronic control device is utilized in an internal combustion engine equipped with an engine-driven pump, using the driving force of the internal combustion engine to circulate lubricating oil, and executing a low-pressure control which restricts the amount of lubricating oil that circulates when there is a small demand for lubricating oil, thereby reducing the driving load of the pump operating in the internal combustion engine. Furthermore, when a prescribed automatic stop condition is satisfied the operation of the engine is stopped automatically, and when a prescribed restart condition is satisfied during the automatic stop the internal combustion engine is restarted. Furthermore, when the internal combustion engine is started in response to the operation of the ignition switch, execution of the low-pressure control is prohibited, but execution of the low-pressure control is permitted when restarting the internal combustion engine.
