Claims

[Scope of utility model registration request]

An intake port that has a helical passage that turns around an opening end to a combustion chamber and a straight passage that linearly communicates with the opening end, and an intake control valve that opens and closes the straight passage is provided in the middle of the straight passage. The intake-exhaust gas recirculation control device for an internal combustion engine has a diaphragm device that opens and closes the intake control valve according to fluid pressure introduced into a diaphragm chamber, and the tire according to the operating state of the internal combustion engine. A fluid pressure supply means for intake control that supplies fluid pressure to the diaphragm chamber of the phragm device, and a valve that is provided in the middle of the exhaust gas recirculation passage and closes when atmospheric pressure is acting on the diaphragm chamber to supply a large amount of fluid pressure to the diaphragm chamber. A Daiwa Ram-type exhaust gas recirculation control valve that opens when fluid pressure other than atmospheric pressure is applied; and an exhaust gas supply that supplies fluid pressure to the diaphragm chamber of the exhaust gas recirculation control valve in accordance with the operating state of the internal combustion engine. a fluid pressure supply means for gas recirculation control, which is sensitive to fluid pressure in the diaphragm chamber of the diaphragm device, and when the fluid pressure is a fluid pressure that acts on the diaphragm chamber to open the intake control valve; and an atmospheric release valve for introducing atmospheric pressure into the diaphragm chamber of the gas recirculation control valve.
