Diesel trucks have been identified by many experts as sources of haze air pollution DPF technology is also widely used abroad
Mercedes-Benz
In Germany, the Mannheim engine plant introduced the OM471 engine called "Blue Efficiency Power." The launch of this engine has made Mercedes-Benz the first truck manufacturer in the world to launch a Euro VI-compliant engine. The OM471 has been specifically developed to meet European emission standards. Its main technologies include SCR (Selective Reduction Control Technology) and EGR (Exhaust gas Cycling technology) and DPF (diesel particle filter technology) etc.
Adams Scania
Two Euro VI engines were released. The biggest feature of these two engines is the emission aftertreatment system. This mainly includes devices such as DOC (Oxidation Catalyst), DPF (Diesel Particle Filter), SCR (Selective Reduction) and ASC (Ammonia Filter). The resulting tail gas is filtered through these systems, and particulate emissions will be reduced by 99%.
Obviously, no matter whether it is the domestic five or the overseas European VI, the DPF technology route is the core! Reducing air pollution from the cargo transportation is indispensable!

Keeping abreast with the international situation Xichai ancestors step
Before the country's five timetable was formally introduced, FAW Xichai has taken a strategic vision, an international perspective, and a smart strategy to actively pursue the DPF-based technology reserve and product development of China's five diesel engines based on the maturity of the DPF technology. , And in the 4DW platform product took the lead in the completion of technology upgrades, the current multi-platform products can be batch production!

Tungsten Carbide Roll Rings, also known as hard alloy roller ring, has been widely used in the rolling production of high-speed wire, bar, threaded steel, seamless steel pipes, etc. due to its good wear resistance, high-temperature hardness, heat fatigue resistance, thermal conductivity, and high strength.
The Tungsten Carbide Roll Rings we produce mostly come in two series: WC Co and WC Co Ni Cr, with Co and Co Ni Cr as binders ranging from 6wt% to 30wt%. From a usage perspective, hard alloy rollers have good comprehensive mechanical properties, with a bending strength of over 2200 MPa and an impact toughness of (4-6) × At 10 ^ 6J/m ^ 2, the Rockwell hardness (HRA) can reach 78~90. During the high-speed wire rolling process, the single groove steel passing amount is much higher than that of cold hard cast iron or high-speed steel rollers.
