According to foreign media reports, Mazda is committed to developing gasoline-powered vehicles in the medium term. The company has invested heavily in developing a revolutionary technology that could be applied to the next generation of small cars.
This technology is called Homogeneous Charge Compression Ignition (HCCI for short) and combines the advantages of diesel and gasoline engines to achieve efficient combustion. The main difference between diesel and gasoline engines is that gasoline engines use spark plugs to ignite the fuel, while diesel engines use pistons to compress the diesel fuel to raise its temperature to the ignition point. Engines using HCCI can ignite gasoline at extremely high pressures without using spark plugs. Several automakers, including GM, Honda, Hyundai, and Mercedes, have tried to use this technology to improve fuel efficiency.
Mazda is not the only company committed to increasing the compression ratio of mass production engines. Nissan's Infiniti brand may also be equipped with a variable compression ratio engine in future models to enable it to minimize fuel consumption and maximize power output based on driver needs.

With this universal tool, you can perform engineering configuration, parameter setting, commissioning, diagnosis and maintenance on intelligent field devices and field components, and fully support Profinet.
Following the establishment of Siemens ’first Asia-Pacific digital experience center in Beijing in June this year, Siemens’ digital experience center for process industries was also opened in Shanghai during the summit. Visitors can experience the real-world experience from integrated engineering to integrated operation and maintenance brought by the "digital twins" to the process industry: integrated design, digital transfer, data management of the entire plant life cycle, virtual commissioning and operator training system , Daily inspections of virtual reality, and in-depth equipment status analysis.
Michelin uses 3D printing technology to enhance the competitiveness of the tire market. Through cooperation with Fives, Michelin will use its co-developed metal 3D printing equipment Addup for the research and development and manufacture of Michelin tire molds, and launched MICHELIN CrossClimate + this new tire product Passing safety certification makes Michelin's tires more competitive in the market.
Just as GE has become a supplier of metal 3D printing equipment through Arcam and Concept Laser, and at the same time, these metal printing equipment are used for the development of its own aerospace, energy and other industries. Through cooperation with Fives, Michelin will use its co-developed metal printing equipment Addup for the R & D and manufacturing of Michelin tire molds, which has become another model of complementarity between business units.
Using metal 3D printing for the manufacture of tire molds, Michelin is not just talking, they have already moved and launched MICHELIN CrossClimate + this new tire product.
In the processing of tire molds, the pattern of tire molds is inherently complex and changeable. As major tire manufacturers increase the complexity of tire patterns and the requirements for tire molds in order to increase competitiveness, tire patterns change very quickly. Diversification and shorter lead times for molds.
Needless to say, the tire pattern is an important and complex and difficult to process. The precision of its processing directly affects the accuracy and quality of the tire, and even the safety of the tire and the comfort of driving. The structure of the pattern often exhibits three-dimensional distortion in space, and the tire pattern has many radians and angles. It is difficult to accurately complete it with traditional processing methods. Even if EDM is used, there are still some problems that are difficult to solve.
During the processing of tire patterns, the processing steps are highly concentrated, mainly milling, but because the processing angles and corners are not uniform, some patterns have thin and high small ribs or narrow and deep small grooves. Including those high and low structures with irregular surfaces, the rigidity of the machine and the requirements of the tool are relatively high.
High-speed milling is not a panacea. The difficulty in designing and manufacturing the movable mold of a radial tire is reflected in the difficulty of controlling the working surface accuracy of the mold, the coordination of the mold opening and clamping mechanism, and the high requirements of the parting surface processing. The surface construction method has a great influence on the working profile of the mold. In addition, if the tool path planning algorithm fails during machining, it will also directly affect the tire quality. 3D printing technology can complete the complexity of shapes that are difficult to achieve by traditional machining. More complex, better grip and stability are undoubtedly the high ground for high value-added tires.
So far, Michelin has felt the potential of additive manufacturing, and claims that the only limitation is the imagination of the designer. Through 3D printing technology, Michelin designed a unique sculpture series MICHELIN CrossClimate + and passed safety certification, making Michelin's Tires are more competitive in the market.
MICHELIN CrossClimate + uses three innovative Michelin elements: innovative tread rubber materials, new tread patterns, and high-performance tire grooves. MICHELIN CrossClimate + retains the performance of MICHELIN CrossClimate tires on dry ground and maintains the positioning of high-end summer tires. But unlike the previous generation MICHELIN CrossClimate, the new product has improved winter performance, and it can perform smoothly even on ice and snow.
For practical reasons and budget considerations, some drivers are unable or unwilling to change tires in winter and summer. Except for some tire performance such as rolling resistance, most of the performance will decrease with the use of the tire, especially the grip of the tire on wet, rainy and snowy roads. The MICHELIN CrossClimate + 's four-season tire positioning can meet the diverse needs of drivers.
This tire can meet the safety of driving in summer (braking distance on dry and wet roads), and can guarantee the mobility and safety of motor vehicles in winter on wet and slippery roads. Michelin claims that the latest traction level of this MICHELIN CrossClimate + tire in the snow is comparable to the high-end four-season tires mainstream in the European market. In the fully worn state, the traction level of the product on the snow is still comparable to the level when the mainstream high-end four-season tires in the European market are in the mid-wear state.
The "V" tread pattern optimizes the tire's grip on snowy surfaces throughout its life cycle. And MICHELIN CrossClimate + has a longer service life than the current Michelin benchmark summer tire MICHELIN ENERGY SAVE +, which is 25% longer than the average high-end four-season tire. In addition, MICHELIN CrossClimate + has hard, chamfered tread blocks to ensure maximum safety for motor vehicles on the road.
CrossClimate + not only has a full-depth 3D groove to provide continuous movement performance for vehicles on rainy or snowy roads, but also has an automatic locking groove to ensure that the vehicle can effectively brake on dry roads. Another highlight of CrossClimate + is that even if the tires are worn, the new grooves on the tread still have traction on the snow-covered road and continue to the last mile.
