Low carbon economy leads to comprehensive innovation in cylinder block manufacturing technology

The cylinder block is generally cast from gray cast iron. The cylindrical cavity in the upper part of the cylinder block is called a cylinder, and the lower part is a crankcase supporting the crankshaft. The inner cavity is a space for crankshaft movement. A plurality of reinforcing ribs, a cooling water jacket and a lubricating oil passage are cast inside the cylinder block. The cylinder block should have sufficient strength and rigidity. According to the position of the cylinder block and the oil pan mounting plane, the cylinder block is usually divided into the following three forms: a general cylinder block, a gantry cylinder block, and a tunnel type cylinder block.
First, the engine cylinder industry will accelerate the process of survival of the fittest
According to the statistics of CATARC, the production scale of China's automobile engine cylinder block was 686,000 in 2007, a decrease of 73.6% compared with 2006. The main reason is that various auto manufacturers have accelerated the main engine parts such as self-produced cylinder block and cylinder head. pace of. However, from April to December 2009, domestic and foreign buyers purchased the cylinder block, cylinder head and cylinder liner through the Gasgoo.com platform. The procurement frequency did not decrease significantly, but generally increased. trend. In December, domestic and foreign buyers used the Gasgoo.com platform to purchase cylinder liners for 102 times, an increase of nearly five times that of April. Due to the easy damage of the cylinder head and the large demand in the aftermarket, the purchase of the cylinder head far exceeds the cylinder block and cylinder liner.
In the context of the global automotive industry entering a low-altitude development in the second half of 2008, for auto and engine manufacturers actively pursuing cost reduction and equipment investment, the goal of focusing on economies of scale is to focus on the external procurement of cylinder blocks. As a manufacturer, the cylinder block industry is bound to face competition from the survival of the fittest.
With the increase in production capacity of Chinese national automobile and engine manufacturers, the supply scale of cast iron cylinder blocks of large ethnic group manufacturers such as Sichuan Sifang Foundry and Shaoyang Shenfeng Power Manufacturing has also expanded. At the same time, suppliers such as Ruiming Group Co., Ltd. and Guangdong Zhaoqing Power Accessories, which produce aluminum casting parts, are also actively working to develop new products and expand production capacity in response to the requirements of supporting manufacturers. However, many national cylinder block manufacturers have an annual production capacity of only tens of thousands, and some manufacturers do not have the ability to cope with the development of new engines, which will accelerate the survival of the fittest in the industry.
Second, the low carbon economy led to the innovation of cylinder block manufacturing technology
In 2009, the Chinese government announced its commitment to reduce carbon dioxide emissions. By 2020, China's unit GDP emissions will be reduced by 40% to 45% on the basis of 2005. At the same time, China will implement the third stage fuel consumption standard in 2015, and the fuel consumption will be reduced by about 15%, which poses a huge challenge to the development of automobiles and their key components.
With the Chinese government's requirements for low-carbon economy construction, the construction of a new engine mass production system has gradually been put on the agenda. As one of the main components of the engine, the cylinder block must face the introduction of modern production management systems such as lightweight, electronic control and environmental protection technologies. Among them, in order to achieve the weight reduction of the cylinder block, the former main production raw material cast iron will gradually be replaced by aluminum. In addition, in order to ensure a stable product quality, die casting technology capable of effectively controlling the weight of materials has also become popular.
In response to the production process of the cylinder block lightweight technology, Geshi Automotive Network will invite the technical director of the automotive engine R&D department of the internationally renowned OEMs to participate in the International Automotive Powertrain Application Technology Seminar held on May 13-14, 2010. Introduce the manufacturing technology of its advanced aluminum engine cylinder block. This technical seminar has been attended by the technical directors of GM China, Shanghai Volkswagen, Changan Automobile and FAW Technology Center. In the same period, Gasgoo.com will also hold a car powertrain and its parts procurement matching meeting, and will invite more than 20 auto parts buyers to release engine and clutch parts procurement projects.
