Description
Technical Field
The invention relates to the field of air inlet assemblies and parts of automobile engines, in particular to a high-efficiency air inlet manifold which has the advantages of saving cost and improving production efficiency.
Background
Intake manifolds are widely used in automotive engine intake systems. In the automotive industry, an air intake system on an engine is responsible for providing ventilation requirements for the combustion of fuel in the engine, and sufficient intake air can be taken to provide sufficient power for the engine; the existing common intake manifold has the advantages that the air inflow to the engine is smaller and the air inflow efficiency is low due to the fact that the engine cabin space is limited, and in the prior art, the intake manifold is used for guiding air into the engine so as to ensure better combustion efficiency and less exhaust emission. However, a common problem with current intake manifolds is that air entering the duct fluctuates due to engine load variations and barometric pressure variations, which can affect combustion efficiency and vehicle performance. In addition, due to dense urban roads, unsmooth traffic flow and other reasons, when the vehicle is blocked, more ground feedback pressure is generated in the air inlet manifold in an idle state of the engine, so that the vehicle performance is further influenced. The double-cavity air inlet manifold is one of important components in the design of the air inlet manifold, and meanwhile, the performance of a product can be effectively improved, so that the purposes of saving cost and improving the production efficiency are achieved. The double-cavity air inlet manifold is provided with the pressure stabilizing chamber on the basis of the original air inlet manifold, so that the air inlet efficiency is doubled, the space problem is solved, the air inlet efficiency of the engine is improved, and compared with the common air inlet manifold, the cost is effectively improved.
In response to these problems, the prior art has proposed some solutions. For example, chinese patent publication No. CN114738150a discloses a bistable cavity intake manifold assembly for uniformly distributing EGR exhaust gas, and belongs to the technical field of intake manifold assemblies. EGR exhaust gas can be evenly distributed, air inlet noise is reduced, and NVH performance is improved. The air inlet flange is located the steady voltage chamber rear end, and four intake ducts are located steady voltage chamber front side, and the gas outlet flange is located four intake duct front sides, and integrated EGR waste gas passageway in four intake duct trough departments sets up the EGR flange in EGR waste gas passageway left side, respectively sets up an exhaust hole on every intake duct, and EGR waste gas passageway communicates with four intake ducts through four exhaust holes. The invention can uniformly distribute EGR waste gas, reduce the radiation noise on the surface of the manifold, improve NVH performance, has compact structure and can improve air inlet performance. The intake manifold is designed to be a double-cavity structure, and besides the voltage stabilizing cavity, a resonant cavity is added, so that on one hand, the effect of stabilizing flow is achieved, on the other hand, the surface rigidity of the manifold is increased, the surface radiation noise can be reduced, and the NVH performance is improved. But these solutions typically require additional equipment and structure to implement and are therefore costly, which can be confusing to the consumer.
