Xiagong Chusheng Wrecker Factory is the largest wrecker production base in China after Guangdong Guangdong Province. It has surpassed Guangdong Guangdong in the production of wrecker production facilities, and it is almost the same in the production process, hydraulic parts purchase, etc. Currently, XCMG's Chu Sheng Wrecker is investing heavily in scientific research. It has developed in the field of major-level wreckers and multi-purpose wreckers. The drag-lifting multi-purpose wrecker has long been available, 60 tons in succession, and super The large semi-trailer will also be successfully developed by the end of 2013.
With the full implementation of the National IV emission standards, many areas in the country’s three models will not be able to get households, resulting in the gradual increase of the National IV vehicles. In order to better serve the road rescue industry, the National IV road wrecker will also be put into mass production. Compared with the "National Sanqing Wrecker Standard", the "National IV Wrecker Standard" has stricter control over the emission of motor vehicles, and it needs to be further reduced by 30% to 50% on the basis of meeting the "National III Wrecker Standard". The pollutants can reach the standard. The ultimate goal of the implementation of the Euro IV wrecker standard is to reduce the emission of pollutants.
For high-power wrecker diesel engines: There are basically two routes
1 Lower NOx through EGR, then reduce PM to Euro 4 level through post-processing techniques such as particle traps or particle oxidizers;
2 By optimizing the combustion system (mainly using high-pressure injection + reasonable combustion organization) to reduce the particles, but at the same time allow the NOx to rise, and then, in the exhaust after-treatment system, the NOx is reduced to Euro 4 level through the SCR catalyst. But in China today, use
Both DPF and SCR have many objective constraints, such as oil infrastructure issues.
For small power wrecker diesel engines:
More realistic technical solutions are: direct injection + supercharged intercooled + cooled EGR + oxidation catalyst + electronically controlled fuel injection system (preferably common rail)
The above is the working principle of the S4 Wrecker engine, and technical issues will be improved in the follow-up work.
Buying a wrecker, the first choice for Xiamen workers Chu Sheng! The best technology, the most affordable price, the most intimate after-sales service!
The national four- platen wrecker is one of the earliest special-purpose vehicles that has been used since the country's full implementation of the National IV Discharge Standard on July 1, 2013. It is an essential special-purpose facility for road clearing and accident rescue, and is used in the Fourth National Wrecker. Both functional and operational efficiency have improved significantly. The newly developed state-of-the-art Wrecker will provide better service to the shipping department, repair shop, and automobile 4S shop. The Hsugong Chusheng Wrecker Factory carefully selects the National Power IV chassis with large power and low fuel consumption to renovate the obstacles. The car and the four-nation wrecker are not only more powerful than any of the previous models in terms of power performance. The gear change is easy and the throttle is slightly faster than the donkey. In addition, the wrecker is driving in the national four wreckers. Comfort and safety are also taken into account. Hydraulic seats, four-point suspension airbag damping, front axle disc brakes, speed limiters, and original air conditioning are all available. Good horses must be equipped with good saddles to complement each other. The country’s four wreckers are so demanding in terms of chassis selection, so they will not be paralyzed in terms of conversion. All hydraulic components are imported, making the hydraulic part of the four wreckers. The operation is flexible and comfortable, and it is more stable and durable. The materials used in the production of wreckers are high-strength and high-quality steel plates, abrasive tools, and one-step automatic mechanical welding. Under the premise of guaranteeing the quality of wreckers, the same type of products will be cleared. Consistency of car models, but also more aspects of the post-sale service tracking.
