機付エンジンの制御装置。[Claims for Utility Model Registration] There are two intake valve holes in the combustion chamber of the cylinder head and two
forming two exhaust valve holes, and connecting one exhaust passage and the other exhaust passage to respective exhaust ports communicating with the two exhaust valve holes, respectively,
A 4-valve type in which both of the above exhaust passages are merged into one exhaust pipe on the upstream side of the turbine of the turbocharger, and both of the above exhaust passages are connected through a communication pipe, and the above exhaust pipe is communicated with the turbine inlet side. In the turbocharged engine, a control valve that is controlled to open and close by an actuator is disposed downstream of the communication port of the communication pipe that opens into the other exhaust passage of the two exhaust passages, and the actuator of the control valve The opening/closing control is performed based on a determination result between the engine rotation speed calculated by inputting a signal detected by an engine rotation speed sensor to a control unit and a preset setting value. A control device for a turbocharged engine.
