Abstract
The invention provides an inlet manifold device of an engine, which comprises an inlet manifold main body. A variable airway length mechanism is integrated on the inlet manifold main body. The variable airway length mechanism comprises an electromagnetic valve, a vacuum hose, an actuator, a valve plate, a bearing and a rotating shaft. The bearing is sleeved on the rotating shaft. The valve plate is fixedly connected to the rotating shaft. When rotating, the rotating shaft drives the valve plate to swing. The actuator is connected with the rotating shaft. When the engine achieves a set rotating speed, the electromagnetic valve can receive a signal sent by an engine control unit and transmit the signal to the actuator and the rotating shaft is driven by the actuator to rotate, so that the valve plate is driven to swing to carry out airway switching. The inlet manifold device of the engine has the beneficial effects that the requirement on the output torque when the engine is in a low-speed state and the requirement on power when the engine is in a high speed state are met; and the oil consumption of the engine and the NOx emission are further reduced.
