As the most growing engine company in the world, Weichai Power is leading the way in China's high-power and high-speed engines . The 10 litre and 12 litre engines are sold well at home and abroad, of which only 12 litres have more than 100,000 engines. "Weichai Power" brand enjoys a good reputation in OEM and end markets. It not only won the favor of mainstream automobile manufacturers such as Shaanxi Auto, Futian, Jiefang, Bei Ben, Jianghuai, and Hualing, but also has many users "fans" and does not hesitate to increase prices. I would rather wait for assembly of the Weichai engine. As the saying goes, the wine is not afraid of the deep alley. Weichai's high-power, large-displacement engines have laid a solid foundation for the market with its outstanding power, low fuel consumption, and reliability. With the increase of the quantity of Weichai products, many application reputations have been accumulated. “High-power, large-displacement selection of Weichai†has become one of the principles for many users to purchase engines. Weichai Power used its strength to create a brand, and more and more users started to choose Weichai and Xinfu. Advance Ni Hongjie, chairman of the China Internal Combustion Engine Industry Association, once commented that the Weichai people have a strong sense of crisis and they are preparing ahead for the development of the next generation of aircraft models. Fifteen years ago, Chinese trucks were mainly equipped with 170 to 280 kW of engine power. After investigating domestic and international commercial vehicle engine markets, Weichai Power found that many heavy truck engines in Europe already have a power of more than 500 kW, and some even reach 600 kW. It is keenly aware that under the macroeconomic stable development of the country, with the advancement of domestic roads and infrastructure, the demand for high-power heavy trucks and construction machinery will continue to increase. Who can develop mature products that meet market needs before the Chinese high-power, large-displacement engine market really starts, and who will stand out in the next round of industry competition? When Weichai's 10-litre engine is sold in the market and people in and outside the industry believe that the Weichai Power will not move any more in the near future, Weichai Power has already prepared for the design, calculation, conceptual design, and theoretical calculation of the 12-liter engine. jobs. In order to launch a new product that can both seize the opportunities and meet the needs of the market very well, Weichai Power has set its own R&D center at the forefront of engine technology in the world, Europe. A batch of batches of Weichai R&D personnel came to Europe one after another, where they communicated with the world's top engine R&D personnel. Not only did they learn the core technologies of large-displacement engine R&D, but they also mastered the design specifications and standard processes of the international engine industry. This laid the foundation for the excellent performance of the 12-liter Weichai engine. After the completion of component design and development, prototype production and trial production, Weichai’s 12-liter engine has invested 16,000 hours of bench tests and two rounds of three-high (high temperature plateau alpine) tests and 10 vehicles and 150,000 kilometers per vehicle. The road tests were all qualified. It is through such rigorous repeated tests, adjustments and re-tests that Weichai's engines have strong competitive capitals such as durability and reliability. After ten years of sharpening swords, he became a steelmaker. In March 2005, Weichai Power introduced the first domestic 10-litre, 12-liter high-power Lanqingguo III engine with completely independent intellectual property rights, marking the entry into the era of independent innovation for China's internal combustion engine manufacturing. In October 2006, Weichai Power announced that the first "12-liter" engine with "gold displacement" had already received orders in bulk and put it into the market. The successful development of the Weichai 12-liter engine is undoubtedly a milestone. In the era of high-power, large-displacement engine market entrenched for multinational companies, it declared that Chinese companies have the strength and ability to develop high-level high-power, large-displacement engine products, breaking the domestic more than 12-liter, 380-horsepower engine The situation monopolized by foreign brands, and continued in the field of engine displacement of more than 10 liters Weichai Power legend. Zhang Xiaoji, Chairman of the China Association of Automotive Engineers, summed up the outstanding technical performance of the 12-liter engine with “Four Moreâ€: stronger, more energy-efficient, more reliable, and safer. Yuejin With the development of the two-polarized truck market and the continuous upgrading of emission standards, Weichai Power is deeply impressed by the need to continuously improve product quality and upgrade product performance to meet higher emission standards and user needs. In 2008, Weichai Power Europe R&D Center integrated the cutting-edge technology of the internal combustion engine in today's world to build the WP12N series engine. This product meets the National III, National IV, and National V emission regulations and is a high-capacity diesel engine for large displacement vehicles. After more than 80,000 hours of rig test, 80 vehicle test roads, the WP12N series engine has accumulated 3 million kilometers of road surface tests for 3 years, and has passed the limit tests such as the plateau, high temperature, and cold regions. Tests have shown that the engine has advanced performance and high reliability. The WP12N reduced the engine's rated speed to 1900 rpm, achieving a major technological breakthrough and reaching internationally advanced levels in terms of economy, power, reliability, and comfort. The WP12N series engine is based on the user's demand for R&D, achieving three major breakthroughs. The first is economic breakthroughs. The WP12N can achieve an economical speed of 1900 rpm, avoiding the high fuel consumption area, and can reasonably match the multi-speed transmission and the small-speed ratio axle, and can improve the dynamic performance and make the common working conditions of the vehicle in the economic fuel consumption area. The second is a breakthrough in reliability. The engine speed was reduced from the conventional 2200 rpm to 1900 rpm, which reduced the line speed of the piston, the crankshaft linkage system, the gear train and the belt system, and improved engine reliability. The overhaul period exceeded 1.2 million kilometers. Blue high pressure oil pump connection structure improves product reliability; third, cost breakthrough. Because WP12N adopts advanced design concept and follows strict design flow, the reliability of the whole machine is high. Cooperation with top-notch suppliers at home and abroad further guarantees the high reliability of parts and components and long maintenance intervals. In addition, the parts of the WP12N are universal. To a high degree, Weichai Power's huge market share ensures that users can enjoy affordable accessories. In 2010, Weichai Power also developed the Lancun Power II generation on the basis of the Blue Power Engine I generation in response to the actual operating conditions, user habits, and changes in market demand of China's heavy trucks. Blue Engine II covers 10 liters, 12 liters, and 13 liters of commercial vehicle engines. It has made two improvements and three improvements. The two configuration upgrades refer to the fuel oil Han Bao-007 and the electromagnetic constant-temperature fan. Their application improves the engine start performance, reduces the failure rate of starter, ring gear, high pressure oil pump and fuel injector, improves the heat balance of the diesel engine, effectively reduces the useless power loss of the fan, reduces the vibration and noise of the diesel engine, and improves the Driving comfort. Through the upgrade of the configuration, Lanqing Power II has achieved the "three low" advantage. In other words, the failure rate is low, the Bluegreen II generation's comprehensive failure rate is reduced by 30%, and the fuel consumption is lower. In the standard operating condition, the Lancun Power II generation reduces the fuel consumption per hour by 2 liters; the noise is lower, and the Lancun Power II generation is in the standard. Under operating conditions, the overall noise is reduced by 2dB. One success may be an accident. The continuous success of Weichai Power in the high-power, large-displacement field is the result of the market's earnest return on researching the market, carefully connecting products, adapting to change, and diligently working for many years. I have no people, I have excellent people, leading half a step, do the industry pioneer. Each company has its own secret of success, but in Weichai Power we see more: after a period of reform and reorganization, a national enterprise has developed its foothold in the market, devoted itself to research and development, step by step, jumped forward, upgraded, and finally entered the industry. leading position.
