Abstract
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.
