Abstract:
A control method for internal combustion engine includes forming an air-fuel mixture leaner than that at a stoichiometric air-fuel ratio in a cylinder by first fuel injection, performing second fuel injection to inject fuel toward the vicinity of a discharge channel of an ignition plug during a period in which the air-fuel mixture is undergoing a low temperature oxidation reaction in a compression stroke, and after the second fuel injection, performing spark ignition by the ignition plug at a timing at which a spark of the ignition plug reaches the fuel injected by the second fuel injection.

Claim (Index 4):
A control device for internal combustion engine, comprising:\n a fuel injection valve for supplying fuel into a cylinder; an ignition plug for performing spark ignition to an air-fuel mixture in the cylinder; and a controller for controlling a fuel injection timing and an ignition timing; wherein the controller performs: first fuel injection to form an air-fuel mixture leaner than that at a stoichiometric air-fuel ratio in the cylinder; second fuel injection to inject an amount of fuel to make an air-fuel ratio of the air-fuel mixture in the entire cylinder including the air-fuel mixture formed by the first fuel injection leaner than the stoichiometric air-fuel ratio toward the vicinity of a discharge channel of the ignition plug during a period in which the air-fuel mixture is undergoing a low temperature oxidation reaction in a compression stroke; and spark ignition by the ignition plug at a timing at which a spark of the ignition plug reaches the fuel injected by the second fuel injection after the second fuel injection.
