A variable intake manifold resonant intake system

Abstract

The invention provides a novel variable intake manifold type resonant intake system, and belongs to the technical field of engines. The novel variable intake manifold type resonant intake system solves the problems that an existing resonant intake system is subjected to serious abrasion on a sealing ring and a driving device is hard to start. The system is characterized in that an intake manifold is divided into a front section and a rear section, wherein the rear section of the intake manifold is close to a resonant chamber; the rear section of the intake manifold is a corrugated pipe; the front section of the intake manifold is a straight barrel type pipeline, and the free end of the front section of the intake manifold is provided with a flange; a first rack which is as long as the front section of the intake manifold is welded on the lower wall surface of the front section of the intake manifold, and the first rack is engaged with a driving device; the driving device is capable of driving the front section of the intake manifold to reciprocate through the first rack, so that the rear section of the intake manifold extends or shortens, and thus the total length of the intake manifold is controlled; and a positioning guiding device is arranged on the front section of the intake manifold and is used for guiding and positioning the front section of the intake manifold. The novel variable intake manifold type resonant intake system is mainly applicable to the field of intake of engines.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a resonant air intake system of a gas engine with a gas mixture formed outside a cylinder. Background technique [0002] With the development of industry, the problem of oil shortage is becoming more and more serious. It is imperative to develop new energy technologies. Gas fuel resources are abundant, including natural resources, such as natural gas, and resources associated with production and life, such as petroleum gas, biogas, and coalbed methane. etc. At the same time, gas fuel has the advantages of low emission pollution and low price, so the development of gas engines has become an important direction for the development of engine technology. [0003] The gas fuel of the gas engine is preferably natural gas. When the natural gas is mixed in the intake port and then enters the cylinder, it will occupy a part of the intake charge, thereby reducing the amount of ...
