Problems solved by technology

[0003] We know that when the engine is running at a low speed, the intake manifold with a longer flow path can increase the intake speed, enhance the inertia of the airflow, and increase the intake air; The slender intake manifold will increase the intake resistance and reduce the intake air volume, thus affecting the performance of the engine

Embodiment Construction

[0021] The present invention will be described in further detail below through specific examples. The following examples are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0022] A variable air intake manifold, which is composed of an upper piece 8, a middle piece 4, a lower piece 5, and a lower two pieces 6. The upper piece, the middle piece, the lower one, and the lower two pieces are interlocked to form the intake manifold Tube, an intake elbow 7 is formed on one side of the intake manifold; a pressure stabilizing chamber is formed between the middle piece and the lower one and the lower two pieces; a number of outlet pipes 3 are formed on the middle piece (in this embodiment, four ), a number of air inlets 18 corresponding to the air outlet pipe are formed on the middle plate in the pressure-stabilizing chamber, and a number of channels 17 are formed between the upper plate and the middle plate, and the plur...

Abstract

The invention relates to variable air volume type air intake branch pipe. Air intake ports communicated with air exhaust pipes are made directly on an intermediate plate in a pressure stabilizing cavity in a way of corresponding to the air exhaust pipes; exchange-over valves are sealed and arranged on the air intake ports; the valve plates of the exchange-over valves are jointly arranged on the same transmission shaft which is driven by a vacuum valve arranged at the input end on the lateral side of the air intake branch pipe to swing; and the vacuum valve is controlled to act by an electromagnetic valve arranged on the lateral side of the intermediate plate of the air intake branch pipe. The electrical control mode adopted in the invention is quick in response, ensures that the most proper air amount is supplied under a corresponding working condition in time, achieves high air volume control accuracy and stability, improves the dynamic property of an engine and increases the air flow rate in a cylinder by improving the air intake speed of the engine at a high rotation speed, so a sub-combustion process is improved and the economy of low-speed fuel oil in the engine is improved.

Description

Technical field [0001] The invention relates to an intake manifold of an engine, in particular to a variable-gas intake manifold. Background technique [0002] The intake manifold of the engine is intermittent and periodic during the intake process, which causes a certain range of pressure waves to be generated in the intake manifold. This pressure wave propagates and reciprocates in the intake system at the speed of sound. If an intake manifold with a certain length and diameter and a resonant chamber with a certain volume form a resonance system, and the natural frequency is coordinated with the intake cycle of the valve, then at a certain speed, before the intake valve closes, A large pressure wave is generated in the intake manifold, which increases the pressure of the intake manifold, thereby increasing the intake air volume. This is the intake fluctuation effect. The current intake manifold is composed of an upper piece, a middle piece, a lower one, and a lower two pieces....
