Abstract
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.
