A transmission mechanism distributes an output torque of the engine to the first rotary machine side and an output member side. A second motor is operated by one of the electric power translated by the first rotary machine and an electric power accumulated in the battery to generate a power. An operating mode can be selected from a first mode in which the output torque of the engine is delivered to the output member side at a first ratio, and a second mode in which the output torque of the engine is delivered to the output member side at a second ratio. The second ratio is smaller than the first ratio. A controller is configured to restrict selection of the first mode when an available output power of the battery to be supplied to the second rotary machine is smaller than a predetermined value.

  • Publication number: 20190048816
    Abstract: A controller for an internal combustion engine includes a processing circuit that performs a dither control process on condition that a temperature increase request of a catalyst is made. The processing circuit operates fuel injection valves so that during the dither control process, one or more cylinders are lean combustion cylinders in a first period and another one or more cylinders are rich combustion cylinders and so that the average value of an exhaust gas-fuel ratio is a target air-fuel ratio in a second period including the first period. The dither control process is restricted in a manner that, on condition that the rich process is performed, the degree of richening of the richest exhaust gas-fuel ratio of exhaust gas-fuel ratios in the cylinders is reduced.

  • Publication number: 20190048814
    Abstract: A variable combustion cylinder ratio control device includes a target ratio setting section and a pattern determining section. The pattern determining section determines a target deactivation interval as a subsequent deactivation interval when the difference between a current deactivation interval and the target deactivation interval is less than or equal to X cylinders, and determines, as the subsequent deactivation interval, an interval closer to the target deactivation interval than the current deactivation interval by X cylinders when the difference between the current deactivation interval and the target deactivation interval exceeds X cylinders. The value of X is a natural number and a variable value that varies in accordance with the operating state of the engine.
