SAIC Fiat Red Rock Cursor13 Engine assures users
Perhaps the Cursor13 engine is not well-known to most people, but as long as the listed joint venture company that develops and produces it, I believe that the majority of fans will be familiar with: SAIC Fiat Red Rock Powertrain Co., Ltd. (hereinafter referred to as Philippine Red ). At the Beijing International Auto Show held in April this year, Shang Feihong held a new press conference for Cursor13 and announced that it has officially begun mass production in China. A few months later, Cursor13 won the hearts of many users with its powerful technical advantages and reliable product stability. Big horsepower without losing stability “At present, my team has a total of 32 Hongyanjieshi heavy trucks, of which three are equipped with Cursor13.†Zhang Zhiyong, head of the Hebei Huangxun Hongxin Transport Team, told the reporter: “The three lions carrying the Cursor13 engine were newly purchased this year. , Buy it is the phase of the big horsepower this feature.Through more than six months of operation, the driver reflects the engine performance is good, strong explosive, because the part of the vehicle is running the mountain line, the driver is willing to open the climbing ability of the vehicle." According to Zhang Zhiyong, his connection with Shang Fei Hong was accidental. No one around him had ever driven a vehicle loaded with a Philippine red engine. “When we purchased the new Lions equipped with the Cursor13, we were also concerned about the fear that ordinary drivers would face difficulties in driving and maintenance due to the use of electronic control technology. However, the 29 Jessie Lions that were used previously left me behind. The impression was very good, and I decided to buy it. For more than half a year, the engine not only maintained a good level of stability but was also very fuel-efficient, which is even more valuable in the downturn of the market,†said Zhang Zhiyong. "According to the company's development plan, we will also purchase a new batch of vehicles by the end of this year or early next year. We will, of course, prefer the new Jieshi carrying the Cursor13." Zhang Zhiyong added. Technology is king The Cursor13 based on Euro VI design uses an exhaust gas turbocharger to achieve the perfect combination of performance, economic efficiency and environmental protection. It can be upgraded to meet the requirements of the National IV emission through the connection of post-processing systems, and can be easily upgraded to the national V, National VI emission standards. It is understood that the Cursor13 has a displacement of 12.88 liters, and the domestic road car application is 350 to 480 horsepower. It is the largest horsepower range in the Shangfei Red Product Line and is mainly used in heavy trucks, construction machinery and generator sets. The easy operation and responsiveness are two other characteristics of the Cursor13, which reduce energy consumption through the unique gear transmission technology and realize the market's requirements for gear response and controllability. The cylinder follows the proven reinforced structure of the Fiat Industry C series. The six-cylinder design with four-valve and overhead camshaft guarantees the overall strength of the engine. Cursor13 further uses a new ribbed cast cylinder body with a rear gear transmission system, a flexible connection oil pan and valve housing design to further reduce engine noise and vibration, resulting in a further increase in ride comfort. Another key technology of Cursor13 is to adopt the latest generation of Bosch electronically controlled common rail system, which can achieve higher injection pressure. According to tests, the minimum fuel consumption rate is up to 188 g/kWh, and the most fuel-efficient speed range overlaps with the maximum torque speed range of 80%, which makes the entire vehicle run almost completely within the economical speed. At the same time, high torque and a wide range of areas can enable the vehicle to reduce the engine speed without changing the speed of the vehicle, and achieve the fuel-saving effect by reducing the fuel injection amount. At the same time, its high pressure common rail injection guarantees fuel economy and smooth running. Cursor13's cutting-edge common rail technology optimizes the vehicle's payload, while the compact layout reduces engine weight and space usage, thereby effectively reducing operating costs and increasing the user's operating capacity. In addition, according to reports, Cursor13 has an oil change interval of up to 150,000 kilometers in the actual operation in Europe and is easy to maintain, effectively reducing maintenance costs and ensuring operating time. During the injection molding process, when the molten plastic meets in the form of multiple strands in the cavity due to the holes in the insert, the areas where the flow rate is discontinuous, and the area where the filling material flow is interrupted, a linear weld seam is produced because it cannot be completely fused. In addition, when the gate injection molding occurs, a weld seam will also be formed, and the strength and other properties of the weld seam are poor. The main reasons are as follows: Pvc Injection,Precision Plastic Injection Mould,Oem Plastic Injection Crate Mould,Plastic Injection Mould Suzhou Dongye Precision Molding Co.,Ltd. , https://www.sjinjectionmolding.com
Processing:
The injection pressure and speed are too low, and the barrel temperature and mold temperature are too low, resulting in premature cooling of the molten material entering the mold and the appearance of weld seams.
When the injection pressure and speed are too high, injection will occur and weld seams will appear. The speed should be increased, and the back pressure should be increased to reduce the viscosity of the plastic and increase the density. Plastics should be dry well, recycled materials should be used sparingly, and weld seams may occur if the amount of release agent is too much or the quality is not good. Reduce clamping force and facilitate exhaust.
2. Mould:
If there are too many gates in the same cavity, reduce the gate or set it symmetrically, or set it as close as possible to the weld seam. The exhaust at the weld seam is poor, and an exhaust system should be set up. The sprue is too large, the size of the gating system is improper, and the gate is opened to prevent the melt from flowing around the insert hole, or use as few inserts as possible. If the wall thickness changes too much, or the wall thickness is too thin, the wall thickness of the workpiece should be uniform. If necessary, a fusion well should be opened at the fusion seam to separate the fusion seam from the workpiece.
3. Plastic aspects:
Lubricants and stabilizers should be appropriately added to plastics with poor fluidity or heat sensitivity. Plastic contains a lot of impurities, if necessary, replace the plastic with good quality.
