An EGR mixing and adjusting apparatus and an internal combustion engine including the EGR mixing and adjusting apparatus. The EGR mixing and adjusting apparatus includes an EGR tube internally provided with an EGR mixing chamber. An exhaust gas inlet communicating with the EGR mixing chamber is provided at a side wall of the EGR tube. A gas guide sliding block is provided within the EGR tube and slides axially therein to block or open the exhaust gas inlet. The EGR mixing and adjusting apparatus includes a driving device to drive the gas guide sliding block to slide to a predetermined open position. The EGR tube uses the exhaust gas inlet to guide exhaust gas into the EGR mixing chamber and mixes the exhaust gas with fresh air inside the EGR tube. The gas guide sliding block slides axially in the EGR tube to block or open the exhaust gas inlet.

A mixed-gas intake device of an engine comprises an air intake duct. A side wall of the air intake duct is provided with an exhaust inlet. The mixed-gas intake device is characterized in that the same also comprises blades disposed in the air intake duct and a flow control device used for adjusting the distance between two adjacent blades. The blades are arranged at an exhaust inlet end. The multiple blades are arranged in a ring. An exhaust intake space is formed between the side wall of the air intake duct and the blades. The mixed-gas intake device uses the flow control device to adjust the distance between two adjacent blades, so as to adjust the amount of input exhaust, thereby eliminating the need to install a dedicated valve. The multiple blades are arranged in a ring, such that exhaust is evenly mixed with air after entering the air intake duct, thereby eliminating the need to install a dedicated mixer, and effectively reducing the overall volume of the mixed-gas intake device. Further disclosed is an engine comprising the mixed-gas intake device.
