Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engine intake manifolds, and more specifically to a pressure slow-release automobile intake manifold. Background Art
[0002] For carbureted or throttle body gasoline injection engines, the intake manifold refers to the intake pipe from the carburetors or throttle bodies to the cylinder head intake passages. Its function is to distribute the air and fuel mixture from the carburetors or throttle bodies to the intake passages of each cylinder; for port fuel injection engines or diesel engines, the intake manifold only distributes clean air to the intake passages of each cylinder. The intake manifold must distribute the air, fuel mixture or clean air to each cylinder as evenly as possible, so the length of the gas flow passages in the intake manifold should be as equal as possible. Conventional engine intake manifolds are made of plastic.
[0003] When the existing intake manifold wants to reduce the pressure caused by the internal gas, first the inner wall of the intake manifold needs to be smooth enough. However, the traditional intake manifold is prone to bring small debris in the air into the pipe when transporting air, which can easily cause wear on the pipe wall and cause adverse effects.

[0026] Two fixed rods 11 are arranged in the shunt pipe 1. The bottoms of the two fixed rods 11 are connected to the inner wall of the top of the shunt pipe 1. The tops of the two fixed rods 11 are respectively connected to two fixed baffles 12. A movable baffle 13 is connected between the two fixed baffles 12.

The gas will flow to both sides of the two fixed baffles 12. When the engine needs to operate at high power, the gas flow rate increases, the intake volume increases, and an impact force is exerted on the movable baffle 13. When a certain impact force is reached, the telescopic rod 14 contracts, thereby compressing the buffer spring 15, and the movable baffle 13 descends. The gap between the movable baffle 13 and the fixed baffle 12 becomes larger, and while the flow rate is reduced, the intake volume flowing from the diverter pipe 1 to the intake manifold 5 increases;

When the impact force is small, the gas flow rate is reduced, and the pressure and impact force of the gas on the pipe wall of the intake manifold 5 are reduced. After the impact force reaches a certain level, one end of the slow-flow baffle 52 drops, driving the limit spring 53 to compress, and the space between the slow-flow baffle 52 and the pipe wall of the intake manifold 5 becomes larger, the space for gas to pass increases, and the intake volume increases.
