Abstract
The utility model discloses a novel variable air inlet manifold of an engine. The air inlet manifold forms a spiral shape and is provided with an air inlet end and an air outlet end. A long air passage and a short air passage are arranged in an air passage inside the air inlet manifold. A rotary valve plate is arranged at the cross section of air inlets of the long air passage and the short air passage. When the rotary valve plate rotates to the air inlet position of the short air passage, the short air passage is closed, and the long air passage is opened, so that the air inlet manifold with a long air passage is formed. When the rotary valve plate rotates to the air inlet position of the long air passage, the short air passage is opened, and the long air passage is closed, so that the air inlet manifold with a short air passage is formed. As the technical scheme is adopted and the rotary valve plate is arranged to switch the long air passage and the short air passage, the length of the air passage of the air inlet manifold of the engine is variable, the requirement of air charging efficiency of the engine under various working conditions is satisfied and the integral operation property of the engine is enhanced. In addition, the main body of the rotary valve plate forms a circular arc shape, so that the rotary valve plate is convenient to guide the air flow in the air passage.
Description
Technical field
The utility model belongs to the technical field of vehicular engine, and specifically, the utility model relates to a kind of new work engine variable intake manifold.
Background technique
The working speed scope of vehicular engine is wide, and in its whole working speed scope, the required air inflow of each operating mode is different, and gas enters in the cylinder by intake manifold.And the airflow pattern of intake manifold at its mouth of pipe place that is installed at present on the motor is constant, influences the flow velocity and the flow of gas, causes fuel oil not mix with air is full and uniform, and combustion efficiency is not high, and fuel economy is low; Simultaneously, motor needs thin and long intake manifold when middle low-speed running in whole operation interval, to obtain the high moment of torsion output of low speed, then needs short and thick intake manifold to obtain big power in high speed.But the length of present engine intake manifold is immutable, when high engine speeds or high-load operation, adopt long intake manifold can cause the charging efficiency deficiency, engine power descends, cause the engine power performance deficiency, when low engine speed or light running, if the length of intake manifold is too short, then gas can not be realized inertia supercharging to improve charging efficiency, causes the moment of torsion of motor to reduce.
