Since its inception, Aowei 6DM heavy-duty diesel engine has placed a strong ambition for the pursuit of technical innovation by FAW Wuxi. Aowei 6DM is the pioneer of the four-valve overhead camshaft technology for domestic heavy-duty vehicle diesel engines. Previously, overhead camshafts were more common in the passenger car field because the centerline of the crankshaft in the camshaft was farther away, so the timing transmission mechanism was more demanding. At the same time, the structural arrangement of the cylinder head was also more complicated. “In the face of difficult problems, we did not shrink back, but concentrated resources to tackle difficult problems. Through continuous efforts and unremitting efforts, we finally successfully solved a series of technical problems to achieve this technology, and introduced this domestic first overhead camshaft. Heavy-duty engine, said the relevant person in charge of FAW Xichai. According to him, due to the cancellation of the valve push rod, valve tappets and other intermediate links, Aowei 6DM heavy-duty diesel engine direct contact valve rocker control valve closing, fast response, higher intake efficiency, timing control is more accurate and reliable. Thanks to the reference of this technology, the combustion of Aowei 6DM fuel is more complete, which makes the engine's performance in terms of fuel economy and stability more prominent, thus technically realizing "leading technology, powerful low consumption."

It is precisely because of this inherent genetic innovation that Aowei 6DM heavy-duty diesel engine surface market changes, always able to technically advance the layout and calmly face a new test. In the face of the full implementation of the state's four environmental protection standards, Aowei 6DM, which has already been able to start the development of new products that can meet China's four emission standards, has become well-established. It is understood that with the strong, fuel-efficient, reliable, comfortable and safe features, Aowei 6DM four machines have been popularized by the market once they have been launched, and they have been recognized by users.

Aowei 6DM heavy-duty diesel engine in the end how much selling? This point, as long as you enter the production line of Aowei 6DM in full swing can get the most intuitive experience. According to reports, as the market continues to be hot, FAW Wuxi had to open up its own horsepower and work overtime to increase production. "Since January 26th, a new round of double-shift production zip training has been carried out. Each production section and functional team system has been linked and rushed to achieve high output," said a production plan officer at the FAW Wuxi Heavy Machinery Division. In order to ensure the on-site distribution efficiency of parts and components, he even moved his office to the site of the workshop, only to be able to coordinate and solve the problems encountered in the production process at the first time.

Quality leading "Wei" earthquake market

In addition to leading technology, there is another important reason behind the popular Aowei 6DM market, which is its legendary superior quality. As a brother product of the Aowei 6DL engine that hit a record of 2 million kilometers without major repairs in the past year, Aowei 6DM has excellent quality comparable to it.

“The quality of Aowei 6DM diesel engine has impressed consumers. According to users’ reports, the A6’s four-machine J6 car is both reliable and reliable, with first-rate quality, peace of mind and fuel economy, and safe driving. It is highly praised by customers. Since January, sales of Aowei 6DM engines in the Tianjin area have increased by 400 units compared to the same period of last year, said marketing staff of FAW Xiicai Tianjin branch.

In recent years, FAW Xichai has always taken the protection of product quality as the top priority in its production and operation work. It has secured key projects such as “reliability strategy engineering”, “zero-kilometer failure rate”, “quality cost” and “new product quality”. The high-end quality of FAW Wuxi Diesel Engine. From "building standards" to "walking the flow," FAW Xichai's concept of "winning by quality" has been applied throughout the entire product life cycle. Its quality and method of quality control have become a model for the quality of independent brands of FAW Group companies. Through the implementation of the "Quality Doors" standard, the status of the "Quality Doors" before the new products are put on the market is clarified, and the "Quality Doors" control is implemented for the four series models at the same time. The quality control is strengthened from the process of the birth of new products, and new products are improved. In order to ensure that new products are successfully put on the market, the six reliability improvement and improvement projects are led by the leaders of the branch management plants, which fully achieve the goal of reliability improvement; around the market feedback issues, rapid analysis and processing, rolling projects, and personnel tracking; procurement work focuses on resources Ensure the transformation of quality-assurance type, strictly implement the new product double-check system, strengthen the evaluation of parts verification, and improve the physical quality conformity of the purchased parts; the on-site production of parts and components uses the “quantitative” distribution and partitioning of station equipment.

"Gravity Die Casting. A permanent mould casting process, where the molten metal is poured from a vessle of ladle into the mould, and cavity fills with no force other than gravity, in a similar manner to the production of sand castings, although filling cn be controlled by tilting the die."

Gravity Die Casting

Sometimes referred to as Permanent Mould, GDC is a repeatable casting process used for non-ferrous alloy parts, typically aluminium, Zinc and Copper Base alloys.

The process differs from HPDC in that Gravity- rather than high pressure- is used to fill the mould with the liquid alloy.

GDC is suited to medium to high volumes products and typically parts are of a heavier sections than HPDC, but thinner sections than sand casting.

There are three key stages in the process.

  1. The heated mould [Die or Tool] is coated with a die release agent. The release agent spray also has a secondary function in that it aids cooling of the mould face after the previous part has been removed from the die.
  2. Molten metal is poured into channels in the tool to allow the material to fill all the extremities of the mould cavity. The metal is either hand poured using steel ladles or dosed using mechanical methods. Typically, there is a mould [down sprue" that allows the alloy to enter the mould cavity from the lower part of the die, reducing the formation of turbulence and subsequent porosity and inclusions in the finished part.
  3. Once the part has cooled sufficiently, the die is opened, either manually or utilising mechanical methods.
