  "textContent": "An engine assembly includes an air inlet pipe having an air inlet, an air supply port, and an air return port. The air inlet communicates with air. The air supply port communicates with an air inlet manifold of an engine. In a length direction of the air inlet pipe, the air return port is located between the air inlet and the air supply port. An air inlet control valve is disposed on the air inlet pipe, and located between the air inlet and the air return port. An exhaust gas return pipe communicates with the air return port. An exhaust pipe communicates with the exhaust gas return pipe and an exhaust manifold of the engine. In the length direction of the air inlet pipe, a distance S between the air return port and the air inlet control valve and an inner diameter D of the air inlet pipe meet S/D≤2.",
