Description

technical field

[0001] The invention relates to the technical field of engines, in particular to an engine air intake control device and the engine. Background technique

[0002] With the development of the automobile industry, its emission regulations are becoming more and more comprehensive, and fuel economy and comfort are also increasingly valued. Therefore, technologies such as supercharging and direct injection are more and more widely used in gasoline engines. In order to further improve the performance of gasoline engines, taking into account high-speed and low-speed performance, variable intake technology has emerged.

[0003] The variable intake technology is realized through the variable intake manifold. In the field of existing engine technology, the variable intake manifold is divided into two intake forms of variable length and variable section. The larger the cross-sectional area of ​​the variable intake manifold, the lower the intake pressure; the smaller th...
