Air intake control device of engine and engine therewith

Abstract

The invention discloses an air intake control device of an engine and the engine therewith, relates to the technical field of engines, and aims to solve the problems that as the area of the air intake cross section of the air intake manifold can not be controlled efficiently in the prior art, the variable control is not stable. The air intake control device of the engine includes a valve mounted in an air intake manifold and a driving mechanism driving the valve to open and close; the valve includes a transmission shaft and a valve sheet, wherein the valve sheet is fixed on the transmission shaft, and the transmission shaft is connected with the driving mechanism; the driving mechanism includes a limiting rod, wherein a first connecting part is arranged at one end of the limiting rod, and a second connecting part is arranged at the other end of the limiting rod; the first connecting part is connected with the transmission shaft, and the second connecting part is connected with a signal actuator; and the first connecting part and the second connecting part are arranged on the same side of the limiting rod. The engine includes the air intake manifold and the air intake control device of the engine. The air intake control device of the engine and the engine therewith are used for controlling the air intake system of the engine.

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...
