Critical breakthrough in key technologies for compression ignition engines
Supported by the "12th Five-Year Plan" National 863 Program, the key technology research and prototype development based on diesel engine homogenous compression ignition engine , through the "production, learning, research" organic combination, collaborative innovation, key technologies in diesel engine homogeneous compression ignition The company has made important breakthroughs and has the potential to promote the application of homogeneous compression-ignition diesel engines and their key technologies to industrialization. The project aims to develop a diesel engine engineering prototype based on homogeneous compression ignition technology, and proposes a new high-density low-temperature combustion technology based on the combustion path control. The R&D personnel optimized the design of the combustion chamber structure and injector parameters, improved the mixing of fuel and air, and achieved high-efficiency clean combustion. Through the injection strategy and optimization of the air system, multi-combustion mode combusting was achieved within the full operating range. Improved balance between NOx, carbon soot, and fuel economy; the late-entry intake valve structure and its application were developed to achieve a variable thermal cycle, providing an effective way to control combustion and emissions and increase thermal efficiency. And applied for international invention patents, has been open in the United States, Russia, South Korea and other countries. The above-mentioned combustion system and control strategy realizes the optimization of the composite combustion mode of the diesel engine in full operating conditions. The preliminary test results show that the original emission of the diesel engine is close to the Euro V emission level, and the simplified post-processor can meet the requirements of Euro VI. The progress and technological breakthroughs of the key technologies of the homogeneous compression-ignition diesel engine mentioned above indicate that by taking a firm foothold domestically, grasping the development direction of international cutting-edge technologies, and enhancing the ability of independent innovation, it is entirely possible to break through the bottleneck of the application of advanced combustion technologies and to break the blockade of some key technologies abroad. To achieve a leap-forward development of China's highly efficient and clean diesel engine technology. At the same time, the promotion process of homogeneous compression-ignition diesel engine technology in the industry is promoted through an efficient and organic “production, learning, and research†cooperation model.
The Rapier Loom is the most commonly used version of shuttle-less weaving
machinery. Its primary features include fast weaving speed, high level of
automation, and maximum efficiency. In addition to the said characteristics
which are inherited from previous shuttle-less weaving machines, the rapier loom
also has its own advantage over them. For instance, its positive weft insertion
mechanism is suitable for weaving a variety of fiber yarns. Moreover, the unique
weft color choosing system allows maximum 16 colors of filing picks to be woven.
With all those matchless features available at a low price, the loom has seed
wide use in weaving dyed yarn, towel, silk weave, wool fabric, and bast fabric.
It also provides an ideal solution for small batch production of fancy
cloth.
Advances in weaving technology will continue to increase the variety of looms
to fit the specific request of consumers. Below are the detailed descriptions of
the benefits for using rapier looms
Extensive Applications
Versatility
Potential Products
1. Equipped with the electronic dobby system, the rapier loom can meet the
rapidly-changing demands for new products. Controlled by the micro-computer, the
electronic dobby system can provide various weft counts in a warp and weft weave
pattern via the programming system. The wide range of complex weaving patterns
create added value for the fabric manufacturer. While the dobby loom is running
in faster, more accurate movement, it also increases the variations of warp
patterns, thereby facilitating the development of new warp weaving process.
What's more, the complex warp weaving pattern is hard to be duplicated by other
manufacturers, thus protecting the new process from being copied.
Further benefits of using the rapier loom include complete functions, high
production efficiency, high automation, safe operation, low noise, and good
weaving quality. Those advantages have made our rapier loom stand out from
market competition.

The state of the art rapier loom
is no longer picky about the texture, specification, and pattern of the textile
raw material, whether it be hydrophobic or hydrophilic, natural fibers like
cotton, flax, wool, and silk or such chemical fibers as dacron and chinlon,
super fine yarn or super bulky yarn, lightweight and thin yarn or thick and
heavy weight yarn, or yarn with simple patterns or complex patterns. As long as
you choose the correct machine model along with proper weaving process, you can
get satisfying products.
The rapier loom when equipped with the dobby
device, or rather, the electronic dobby loom allows operators to change the
weaving patterns conveniently. That being said, the loom can be converted to
accommodate another variety of product.
The quality, rich-colored fabrics
manufactured by the rapier loom possess huge potential on the market. The rapier
loom makes new product development a possibility.
2. The
rapier loom relies on the rapier to carry the weft across the warp sheet.
Therefore, the loom can insert literally any kind of filling picks into the warp
as long as the pick can be carried by the rapier. Based on this proven theory,
we can use the rapier loom to weave various stretch fabrics like the stretch
poplin, stretch denim, and stretch corduroy. When weaving those fabrics, the
loom has overcome the common problems such as undesired double pick and weft
kink face by previous weaving machines.
3. When fitted with the highly
advanced weft selection device, our electronic dobby loom can construct complex
2-pick and 3-pick weave.
4. The strong battening force and the strong
temple(which can hold the whole width of the fabric and assures the fabric to be
firm), along with the tall back warp beam ensure the fabric is tightened under
high tension throughout the weaving process.
5. The rapier loom, when
equipped with jacquard shedding system, can fabricate weave complex jacquard
pattern. If used in combination with the hot cutter and heat setting device, the
loom can be used to weave product trademarks. It can fabricate top-class weaves
when equipped with selvedge forming device and carving device. Others can be
sued to craft terry towels.
