Abstract
There is provided an operation control method for an internal combustion engine, in which if an exhaust gas purifier needs to be warmed, a second glow plug is heated in an exhaust passage upstream of the purifier to a fuel ignition temperature or higher while fuel supplied to the exhaust passage is ignited and burned. In this method, if it is determined that the purifier and an engine need to be warmed, a first glow plug disposed in a combustion chamber is first heated to a predetermined temperature prior to the warm-up of the purifier to start the warm-up of the engine, and then the second glow plug begins to be heated when the temperature of the purifier is equal to or higher than a glow plug energization starting temperature which is lower than a warm-up start determination temperature of the purifier.
