Recently, Xu Di has successfully trial-produced three new models: XCG215LC-8, XCG260LC-8, and XCG360LC-8. These products are the result of independent research and development, showcasing the company's growing technological capabilities in the construction machinery industry. At the heart of these machines is the engine, which plays a critical role in determining environmental impact. To ensure compliance with modern emission standards and improve performance, all three models are equipped with the world-renowned American Cummins engine.
The engines feature advanced Electronic Fuel Injection (EFI) technology, utilizing a high-pressure common rail fuel system that delivers injection pressures up to 1600 bar. This cutting-edge system significantly enhances both power output and fuel efficiency. Compared to traditional non-electronic injection engines, these EFI engines offer a 5%-10% increase in power, a 5%-15% reduction in fuel consumption, and a 20% decrease in harmful emissions. As a result, they meet the stringent third-stage European emission standards, making them highly efficient, powerful, and environmentally friendly.
The water-cooled, turbocharged diesel engines used in these models are designed for low fuel consumption, low emissions, low noise, and high efficiency. Their eco-friendly design helps reduce environmental pollution, aligning with global sustainability goals. The EFI system itself consists of three key components: the fuel injection circuit, a group of sensors, and the electronic control module (ECM). Among these, the ECM is the most crucial part, responsible for managing and optimizing engine performance.
One of the major challenges during the development process was ensuring seamless data exchange between the ECM of the EFI engine and the overall machine’s electrical control system. This required careful coordination between different control systems. Xu Di’s engineers successfully addressed this issue by modifying the main controller’s control mode, enabling smooth communication between the throttle command and the engine’s ECM command.
However, the complexity of the ECM, which contains highly sophisticated electronic components, also posed challenges in terms of electromagnetic compatibility. Ensuring that the electrical components could operate reliably under various conditions made the design and selection process more demanding. Despite these obstacles, Xu Di’s technical team overcame these difficulties, demonstrating their expertise and commitment to innovation. Their success marks a significant milestone in the company’s journey toward developing high-performance, environmentally responsible construction equipment.
Polypropylene anti corrosion Bitumen Tape
The advantages of modified bitumen anti-corrosion tape: 1, modified bitumen anti-corrosion tape with high elongation, resilience, and thus can largely overcome the substrate deformation caused by the fracture of waterproof materials caused by leakage, waterproof, good sealing, and can be achieved since the fusion.
2, has the ability to resist soil stress damage, strong impact resistance.
3, high electrical insulation, excellent aging resistance stability, strong resistance to ultraviolet radiation.
4, modified bitumen anti-corrosion tape can be self-fusing, even if it enters foreign bodies or is pierced by foreign bodies can quickly repair itself, restore the original state, to ensure no seepage and no leakage.
5.The tape can be wound in a single layer to achieve ordinary or reinforced anti-corrosion. Change the traditional tape need multi-layer winding, reduce the anti-corrosion operation process of human factors on the quality of anti-corrosion caused by the impact, reduce the construction costs.
6, modified bitumen anti-corrosion tape construction is simple, fast, no curing time, manual, mechanical work can be, shorten the construction cycle.
7, cold construction without hot melt or other adhesives, simple, reliable, environmentally friendly, unique sub-waterproof function, can be caused by the coil breakage of leakage limited to the local range, well avoid the overall failure of the waterproof layer.
