POWER OUTPUT DEVICE, INTERNAL COMBUSTION ENGINE DEVICE, AND METHOD OF CONTROLLING THEM

摘要

On the occasion of a cutoff of fuel supply to an engine in an accelerator-off state, the invention expands a throttle opening over a specific throttle opening set in the state of idling of the engine at the reference rotation speed Nref2 (S330). On resumption of fuel injection to the engine, the invention reduces the throttle opening to the specific throttle opening set in the state of idling of the engine at the reference rotation speed Nref2 (step S340). Under no control of lowering the rotation speed of the engine by a motor or under the condition of low vehicle speed with control of lowering the rotation speed of the engine by the motor, the invention resumes fuel injection to the engine resumed with setting of a smaller correction amount T2 to a fuel increase correction amount Ta (steps S400, S420)
