In order to meet the demand of China's auto market for reducing carbon dioxide emissions, MANN+HUMMEL has successfully developed variable intake manifolds and plastic intake manifolds independently, which can reduce fuel consumption more effectively and has now achieved mass production. A variety of models.
As one of the most important parts of the engine intake system outside the intake manifold core functions to provide high volumetric efficiency of the engine, engine efficiency and performance competitive, and its structure affect the overall quality of performance of the engine The key factor. German filtration specialist MANN+HUMMEL not only has complete filter products and plastic products, but also has a wealth of filtration and engine plastic components, such as intake manifolds, oil separators, crankcase ventilation systems, etc. Independent research and development and production experience provide high quality and high performance products and solutions for major domestic and foreign OEMs.
Mannheimer intake manifold
Patented technology effectively reduces fuel consumption
In the intake manifold, MANN+HUMMEL has developed patented rotary valve technology that is the industry's leading technology. By switching the length of the air channel and applying the principle of pressure pulsation, the engine performance at different speeds can be taken into consideration to increase the volumetric efficiency and maximize the medium and low speed. Torque, and greatly increase the engine power at high engine speed, bring more effective "fiery capacity" to the car, so that it can improve engine efficiency more effectively than similar products with the same power output.
Adhere to independent research and development to meet customer needs
While adopting advanced technologies (such as rotary valve switch), MANN+HUMMEL has nearly 100% of its own design and production process for its own air intake manifold. The R&D capabilities have been continuously improved to provide reliable performance of the intake air. Manifold products to meet the higher needs of customers.
In the design of the intake manifold, MANN+HUMMEL has a professional design team. In the early stages of development, professional simulation software was used to verify the function of the intake manifold. Engineers can measure the deformation characteristics of the engine under working conditions and design the engine interface according to the size of the cylinder head to ensure that the seal is firm so that the designed intake manifold can maximize the dynamic and volumetric efficiency of the engine. MANN+HUMMEL also applies the requirements of the host plant throughout the design of the intake manifold. It requires the designer to thoroughly understand the engine and develop a product that meets the requirements.
In the production process of the intake manifold, in addition to using the most widely used vibration friction welding process, MANN+HUMMEL has continuously introduced new technologies for manufacturing and assembly processes, such as hot gas welding technology. These new technologies enable the miniaturization and lightweight design of the intake manifold to produce cleaner intake manifolds. MANN+HUMMEL is also increasingly using rotary core-pulling mold technology to achieve an injection molding of the air passage to make the inner surface smoother, thereby reducing or even eliminating the welding process to meet the increasingly stringent cleanliness requirements of the engine. .
Strict control of product quality
As one of the most essential components on the engine, the detection of intake manifold is very important. Before the final release, it must be strictly tested through some tests to ensure its function and performance, such as tightness test and burst pressure test. , Variable helium tube valve rotation function test, heat aging and durability test, and other functional test, otherwise when it fails, it will lead to abnormal engine operation, brake weakness, engine spontaneous combustion and other serious accidents. In order to meet the demand for quality testing, MANN+HUMMEL uses MMS (Manmoomer Management System) to ensure that all activities such as factory production and quality inspection can be performed in an orderly manner. In addition, MANN+HUMMEL also invests in advanced laboratories that monitor cleanliness and can monitor the weight and size of contaminant particles in the intake manifold.
Tighten the pulse of the market to lead the development of the industry
In the next three to five years, the demand for turbocharged engines in the automotive industry will continue to increase. At the same time, the demand for reducing the proportion of engine space and cooling the intake air temperature is also increasing. MANN+HUMMEL has been well-prepared to meet these needs. For example, it has developed a plastic intake manifold that can withstand 200°C continuous high temperatures. In addition, MANN+HUMMEL is working with other OEMs to develop integrated, intercooled intake manifolds, which have achieved important phase results and will soon be put into use in the market.
With its stable quality and excellent service, MANN+HUMMEL's independently developed intake manifold has been adopted by world-renowned car manufacturers and continues to receive favorable reviews. In the area of ​​traditional engine peripheral components, MANN+HUMMEL has also been committed to the frontier areas of the current automotive industry, using its own profound technological accumulation and manufacturing technology to make its own contribution to energy conservation and emission reduction.
