Abstract

The present invention relates to a control system for an internal combustion engine. The control system performs the corrosion control periodically to corrode the whole surface of an engine componentin contact with a condensed water. The corrosion control includes a set of front half control and a rear half control. The first half control is performed within a first time period from the time (t2)to the time (t3), in the front half control, the engine (12) is operated in a predetermined operating area, and the rear half control is performed within a second time period from the time (t3) to the time (t4).

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119 to Japanese Patent Application No. 2018-236771 filed on December 18, 2018. The entire content of this application is hereby incorporated by reference. technical field [0003] The present disclosure relates to a control system for an internal combustion engine (hereinafter also simply referred to as "engine"). Background technique [0004] JP 2010-121574 A discloses a control system for an engine including an EGR (Exhaust Gas Recirculation) device. In this conventional system, when a predetermined stop condition is satisfied, automatic stop control of the engine is performed in principle. However, in this conventional system, if the temperature of the wall surface of the EGR passage is lower than a predetermined temperature, execution of the automatic stop control is prohibited. In short, even if the stop condition is satisfied, the engine is operated and the aut...
