The 6DM3, 6DM2 and 6DL2 V5 diesel engines passed the new product certification, adopting an independently developed high burst pressure engine structure and lightweight design, a low particulate distributed combustion system, a common rail injection system, an electronic control unit (ECU), and an air drive. Eight innovative technologies such as the urea injection system won 6 inventions and 36 utility model patents. The effective thermal efficiency of the products is about 45%, of which the 6DM2 and 6DM2 five-diesel B10 have a life span of 1.5 million kilometers, inherited from the low fuel consumption characteristics of the strongest Chinese “core†and it is expected that the carbon dioxide and nitrogen oxide emissions per 100 kilometers will be higher than the same power. Less 3%-5% diesel engine. The other two models are 4SL2 and 6SL2 National V natural gas engines. They have adopted natural gas multi-sequence sequential electronic control injection systems, large-flow gas nozzles, high-efficiency lean combustion technology, high-energy ignition systems and other innovative technologies to solve natural gas engines. The technical difficulties of each cylinder's uniformity, high accuracy and high-responsive gas control, exhaust valve reliability and long life, etc.; 4 invention patents and 10 utility model patents. The product's effective thermal efficiency is up to 38% and the power is close to 90% of that of the same displacement diesel engine. It can not only achieve green emission, but also has much higher power than similar natural gas engines. In addition to actively deploying five new products, Xichai was the first to install particulate matter traps (DPFs) on Conway 4DW State V engines in accordance with the "Six National Technology and Five National Application" concepts, capable of capturing 95% of diesel engine emissions. The above carbon particles, through active regeneration, oxidize and evaporate the deposited carbon particles to achieve green emission. Prior to this, the DPF technology route was only stipulated in the Euro VI emission phase. Xichai was the first domestic diesel engine manufacturer to use this technology and put it on the market in batches. At present, there are more than 600 announcements for the 4DW state-owned five-engine vehicle models. Last year, Xichai also aimed at the school bus market to launch the 4DW state-owned five-vehicle special school bus power to realize the strategic layout of mainstream school bus production enterprises in Yutong, Jianghuai, Dongfeng and Chang'an industries. After the use of users have said that the engine does not burn urea, run light urea a year can save about 1,000 yuan, in addition there is no urea crystal worries. From January to March, the sales volume of 4DW five-engined trucks and buses exceeded 4,500. These clean and efficient powers contributed to the city's efforts to rectify and replace the blue sky. Topkit tower cranes are commonly used in construction projects, particularly in high-rise building construction. They are known for their versatility, reliability, and ease of use. The counterweight system can be adjusted to accommodate different lifting requirements, making them suitable for a wide range of applications. 5T Tower Crane,Topkit Tower Cranes,Tower Cranes,5T Hammer head Tower Crane,Hammer head Type Tower Crane SHEN YANG BAOQUAN BUSINESS CO., LTD , https://www.sytoplesstowercrane.com

Some advantages of topkit tower cranes include:
1. High lifting capacities: The top-mounted counterweight system allows for increased lifting capacities, making them suitable for heavy lifting operations.
2. Increased hook height: The counterweight system also enables higher hook heights, allowing for efficient construction of tall structures.
3. Easy assembly and disassembly: Topkit tower cranes are designed for easy assembly and disassembly, making them convenient for construction sites with limited space or frequent crane relocation.
4. Versatility: These cranes can be equipped with various types of jibs and attachments to meet different project requirements, such as luffing jibs for working in confined spaces or jibs with multiple trolley systems for increased productivity.
5. Cost-effective: Topkit tower cranes are generally more cost-effective compared to other types of tower cranes, making them a popular choice for many construction companies.
Overall, topkit tower cranes are widely used in the construction industry due to their high lifting capacities, versatility, and ease of use. They play a crucial role in the efficient and safe execution of construction projects.
At the two conferences in 2017, the government work report stated that we must resolutely fight for the “Blue Sky Battle†in 2017. For a moment, the auto industry has caused a green whirlwind. As we all know, Xichai has been actively responding to the national call for energy-saving and emission reduction, and has taken the lead in constructing a national five-product platform. Recently, five countries and five products have joined Xichai’s “Five National Families†through the identification of scientific research achievements and new products. Up to now, Xichai's five product displacements have covered 2-13 litres, the power has covered 40-500 hp, and the state-owned five-wheeler model has more than 2100 announcements. The technology products have matured.
