摘要： PROBLEM TO BE SOLVED: To provide a controller for an internal-combustion engine capable of conducting changing-over of the suction valve working mode at a proper timing in case the lean burn operation is conducted after fuel cut restoration.
SOLUTION: Fuel cut is executed when the internal-combustion engine 2 is in deceleration. A variable dynamic valve system 10 can change over the operation of the suction valve 8 between the two-valve working mode and the single valve working mode. If the fuel cut is executed in the two-valve working mode, changing-over is made into the single valve working mode before the engine 2 returns from the fuel cut.

摘要： PROBLEM TO BE SOLVED: To provide a fuel reforming device, capable of improving exhaust gas purifying performance after restart of an internal combustion engine which is operated intermittently. SOLUTION: When an engine 5 which is operated intermittently by an engine control part is stopped by intermittent operation, the operation of the engine 5 is extended in a case where temperature of a purification catalyst 61 is lower than determination reference temperature Tc. After injection of reforming fuel by a reforming fuel injector 55 is stopped, the engine 5 is operated for N-cycles before operation of the engine 5 is stopped. Temperature of the purification catalyst 61 is thus raised by exhaust gas after injection of the reforming fuel is stopped, so that temperature of the purification catalyst 61 is higher compared with a case where the engine 5 is stopped simultaneously as the injection of the reforming fuel is stopped. Exhaust gas is more easily purified by the purification catalyst 61, and purification performance of exhaust gas after restart of the engine 5 which is operated intermittently is thus improved.
