摘要： An engine controller controls a direct fuel-injection, spark ignition engine including a fuel injection valve configured to directly inject a fuel into a cylinder, and an ignition plug that spark-ignites a mixture in the cylinder. The engine controller is provided with an acceleration request sensor configured to detect an acceleration request of a driver, and when the acceleration request occurs and a top surface temperature of a piston in the cylinder is lower than a predetermined temperature, the engine controller retards an ignition timing so that a period of time until a flame after the ignition reaches the piston top surface is extended.

摘要： In the present invention, an internal combustion engine (1) is mounted for power generation in a series hybrid vehicle and has an exhaust system with an upstream-side catalytic converter (8) and a downstream-side catalytic converter (9). When the temperature of the upstream-side catalytic converter (8) at starting of the internal combustion engine (1) is lower than or equal to a threshold value, the internal combustion engine is operated at low rotation speed and low load with significant ignition timing retardation. When the warm-up of the upstream-side catalytic converter (8) is judged as completed based on the amount of heat input thereto, the internal combustion engine is shifted to operation at rotation speed and load in the vicinity of the optimal fuel consumption point with the ignition timing set in the vicinity of MBT. The operation of the internal combustion engine (1) is continued, regardless of the power generation request, until the warm-up of the downstream-side catalytic converter (9) is judged as completed. When the warm-up of the downstream-side catalytic converter (9) is judged as completed based on the amount of heat input thereto, stopping of the internal combustion engine is permitted.

摘要： An engine control device controls a cylinder direct fuel injection type spark ignition engine provided with a fuel injection valve configured to directly inject fuel to a cylinder and an ignition plug configured to perform spark ignition for a gas mixture inside the cylinder. In a case where it is necessary to warm up an exhaust gas purifying catalyst disposed in an exhaust passage, the engine control device executes a catalyst warm-up operation in which a fuel is injected at a timing during the compression stroke, and at a timing when the fuel spray colliding with the piston crown surface moves toward the ignition plug along the shape of the piston crown surface, and in which the ignition timing is after compression top dead center. The engine control device advances the fuel injection timing in accordance with an increase in an estimation amount of a liquid fuel remaining on the top surface of the piston during execution of the catalyst warm-up operation.

摘要： Exhaust particulates are collected by a GPF(gasoline particulate filter) device. EGR control is executed, and exhaust gas flowing through an exhaust passage upstream of the GPF device is introduced into an intake passage via an EGR passage. In the EGR control, an opening area of the EGR passage is controlled to reduce the opening area of the EGR passage according to an operating state of the engine as a particulate deposition amount in the GPF device is increased.
