Control system for internal combustion engine

A control system (50) for an internal combustion engine (10) has an intake valve (20), an exhaust valve (21), and an exhaust purifying catalyst (12a)that purifies exhaust gas after combustion of a fuel. During a fuel cut in which no fuel is supplied, a closing timing of the intake valve (20) is cont...

Zusammenfassung:	A control system (50) for an internal combustion engine (10) has an intake valve (20), an exhaust valve (21), and an exhaust purifying catalyst (12a)that purifies exhaust gas after combustion of a fuel. During a fuel cut in which no fuel is supplied, a closing timing of the intake valve (20) is controlled to a delayed angle side more than at a timing when the fuel is supplied and to a delayed angle side more than at a timing at a bottom dead center of an intake stroke, and an opening timing of the exhaust valve is controlled to an advanced angle side more than at the timing when the fuel is supplied and to an advanced angle side more than at the timing at the bottom dead center of an expansion stroke.
