Abstract: A vehicle (3) is provided with an engine assembly (2). The engine assembly (2) comprises an exhaust gas recirculation system (1). The exhaust gas recirculation system (1) comprises an air inlet pipe (100), an air inlet control valve (200), an exhaust gas return pipe (300), and an exhaust pipe (400). In the length direction of the air inlet pipe (100), an air return port (130) is located between an air inlet (110) and an air supply port (120). The air inlet control valve (200) is located between the air inlet (110) and the air return port (130). The exhaust gas return pipe (400) separately communicates with the exhaust pipe (300) and the air return port (130). In the length direction of the air inlet pipe (100), the distance between the air return port (130) and the air inlet control valve (200) is S, the inner diameter of the air inlet pipe (100) is D, and S and D meet S/D≤2.
