A control device in an internal combustion engine, interlocking with a device to generate swirls in a combustion chamber of the internal combustion engine by providing bypass passages which allow air to bypass a throttle valve for regulating intake air flow rate of the internal combustion engine to control an output power of the internal combustion engine and allow the air to flow in from the side of atmosphere to communicate with air intake ports for respective cylinders on the downstream side of the throttle valve. The device comprises sensors to detect a vehicle speed, a gear position, an opening of an accelerator, an intake air flow rate and the like and a processor to determine an operating state of the internal combustion engine such as a rotating speed, a torque and the like based on the signals from the sensors, calculating an operating condition of the internal combustion engine according to the strength of swirl to be generated based on the operating state, outputting the calculated values as control signals.
A control device in an internal combustion engine, wherein a swirl generating device operatively associated with the control device is configured to generate swirls in a combustion chamber of the internal combustion engine and includes bypass passages which allow air to bypass a throttle valve for regulating intake air flow rate of the internal combustion engine to control output power of the internal combustion engine and to allow the air to flow in from atmosphere to communicate with air intake ports of the internal combustion engine for respective cylinders on a downstream side of the throttle valve, wherein the control device comprises
