Variable intake manifold, engine and vehicle

Abstract

The invention discloses a variable intake manifold, an engine and a vehicle. The variable intake manifold comprises an intake manifold body and a baffle. A first air channel is formed in the intake manifold body. The intake manifold body is provided with a baffle channel communicated with the first air baffle. The baffle can move along the baffle channel and has a stretching-out state of blocking the first air channel and a shrinking state of shrinking into the baffle channel. The variable intake manifold further comprises a driving mechanism to enable the baffle to be switched between the stretching-out state and the shrinking state. The engine comprises the variable intake manifold. The vehicle comprises the engine. The variable intake manifold has the advantages of being simple in structure, convenient to install and maintain and low in manufacturing cost.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a variable intake manifold, an engine and a vehicle. Background technique [0002] Technologies such as variable intake swirl are increasingly used in the vehicle field, especially in the intake manifold of the engine, but most of the existing variable intake manifolds have complex structures, for example, the existing variable intake manifold In the air manifold, the drive shaft of the variable mechanism runs through the air channel of the manifold, and the baffle plate used to block the air channel is set on the drive shaft. In these two states, the baffle and drive shaft always exist in the air passage, which inevitably creates resistance to the intake air, leading to problems such as large intake resistance and uneven intake air, which affect the effect of variable intake air In addition, due to the complex structure of the existing variable intake manifold, a large number of compone...

[0002] Technologies such as variable intake swirl are increasingly used in the vehicle field, especially in the intake manifold of the engine, but most of the existing variable intake manifolds have complex structures, for example, the existing variable intake manifold In the air manifold, the drive shaft of the variable mechanism runs through the air channel of the manifold, and the baffle plate used to block the air channel is set on the drive shaft. In these two states, the baffle and drive shaft always exist in the air passage, which inevitably creates resistance to the intake air, leading to problems such as large intake resistance and uneven intake air, which affect the effect of variable intake air In addition, due to the complex structure of the existing variable intake manifold, a large number of components need to be arranged in the small layout space of the intake manifold, and there are also problems of difficult assembly, high cost and short service life , for example, the drive shaft is slender, the installation process of assembling into the airway is complicated, and it is easy to bend and deform when rotating, or even break
