According to the National Bureau of Statistics, 427,600 cars were produced in China last month, up 60,000 from August and an increase of 36.8 percent from a year before. Car output in September hit a monthly record high, exceeding 421,900 in March this year, the previous record-holder. Sedan output hit 191,300 in September, exceeding 190,000 for the first time, up 21,900 from a month before and an increase of 69.7 percent from the previous year. ====================================================================== (2) OTIS-LG to Make 340 Elevators for China (Source : CMES) OTIS-LG, a joint venture between the multinational elevator firm OTIS and Korea's LG Group, has won an order to supply 340 elevators, worth 9 million US dollars in total, to China. The firm says the order is its largest to date. The elevators will be installed at office buildings to be built in the Advanced Business Park in Beijing. OTIS-LG has supplied about 16 thousand elevators to China since it first started doing business here in 1995. ====================================================================== (3) European Gas Heater Manufacturers Eye Chinese Market (Source : CMES) European manufacturers of individual gas heating systems are pinning high hopes on the booming Chinese market as the country sees rapid economic growth and greater awareness of environmental protection. China's ongoing project to build a 4,000-kilometer cross-country gas pipeline has further encouraged European companies who have occupied 50 percent of the Chinese market in less than five years, defeating their Republic of Korea rivals who entered China in the mid-1990s. A total of 120,000 individual gas heating systems are sold in China annually, with sales of more than 600 million yuan (73 million US dollars). Most are imported, but in recent years, Sino-foreign joint ventures have begun to manufacture the heaters in China, while some local companies are producing the products with foreign technology. Representatives from 12 European companies and Chinese experts and officials attended the European Individual Gas Heating System Symposium, which was sponsored by the Sino-French Professional Training Center on Energy. The European companies are Ariston, C&M, Hermman, Aereco, Bosch, De Dietrich, Immergas, Beritta, Buderus, Frisquet, Rettig, and Wilo. ====================================================================== (4) US Pump Firm Nears Acquisition Deal in Shanghai (Source : CMES) The United States-based company ITT Industries Inc., the world's largest provider of pumps and fluid technology systems and services, said in Shanghai on Oct.22 it is close to acquiring a local private waste-water treatment company. The details will not be announced until November, but the acquisition is regarded as testimony to the company's future strategy in China, involving more acquisitions in the coming years. Mark Steele, president of the ITT Industries (China) Investment Co. Ltd., said: "We have high aspirations for our business in China, especially in the water and waste-water area. "We hold these expectations because China is the fastest-growing market for us, and we see huge opportunities here." ITT has so far set up 10 manufacturing facilities around China, involving combined investment of more than US$100 million. Three of the facilities are engaged in the fluid technology business, involving the production of pump systems and related equipment for water management and waste-water treatment. The rest are in the electronic components business. Water-related businesses are expected to be a high-growth area for future ITT operations in China. Pumps produced by ITT operations in China have been widely used in projects such as the Three Gorges Dam project, the Xiaolangdi Reservoir project on the Yellow River, and the Suzhou Creek rehabilitation project in Shanghai, the company said. The pumps involve brands such as Flygt, Goulds, Lowara and Sanitaire. According to Steele, top ITT officials have held initial yet "constructive" discussions with water authorities under the State Council regarding the company's involvement in China's ongoing massive south-to-north water diversion project, which involves total investment of over US$60 billion. ====================================================================== (5) Development of Micro Shape Machining Technologies (Source : JSME) Masahiro Muro Matsushita Electric Industrial Co., Ltd. Micro mechanical devices and these applications have been increasing. The micro electro-discharge machining (EDM) and the micro grinding technologies applied to those devices are introduced. The micro EDM has achieved to bore micro holes as small as 5 micron diameter by minimizing discharge energy less than 10-7J. The deviation of the diameter in the case of 20 micron diameter holes into the stainless steel plate is less than 0.3 micron. By using a brass plate electrode which has several micro holes, a block workpiece can be plunged to micro pin array at the same time corresponding to the micro holes on the brass plate. Micro optical devices are required around 0.1 micron profile accuracy and less than 20 nm surface roughness, so the micro grinding technology has been developed. The micro EDM process on the machine can true the micro size grinding tool made of polycrystalline diamond. A micro cylindrical lens that has 150 micron radius and 1 mm length is finished with the micro grinding method in the above accuracy and surface roughness. To accomplish higher accuracy and more complex shape machining, applications of micro shape machining technologies will be increased in the future. ====================================================================== (6) Numerical Simulation of Fuel Injection and Droplet Motion (Source : JSME) Kazuhiko Suga Toyota Central R & D Labs., Inc. Experimental studies of liquid atomization and spray have contributed to designing fuel injectors of jet and IC engines. However, the phenomena are still not very well understood because they are very complicated multiphase fluid motions occurring in a very tiny area. Due to the recent development of digital computers, highly complicated and large scale numerical simulations for multiphase flows are getting affordable. Accordingly, we have established a numerical code for simulating gas-liquid two-phase flows. The numerical scheme used for tracking the gas-liquid interface is the level set method. Some recent our results of numerical simulations related to fuel injection and the subsequent droplet motions are introduced. The example case of liquid jet breakup simulation which is relevant to pre-mixed fuel injection is at Re=15000, We=10000 and the liquid-gas density ratio of 800. The results of the binary droplet collision simulation of the off-center separation with satellite droplets are also shown. We believe that such a simulation is a powerful tool for understanding the phenomena and designing fuel injection systems in the near future. ====================================================================== (7) Manual regeneration type DPF (Source : JSME) Masanori Komori COMOTEC Corporation The Environment Security Ordinance will be effective from October, 2003 in the Tokyo Metropolitan area and three prefectures. The vehicles with diesel engine which don't meet the standard of PM (particulate matter) emission will be prohibited to run in these areas without DPF (Diesel Particulate Filter) by this regulation. Types of DPF are classified into automatic regeneration DPF such as intermittent collection-regeneration type and continuous collection-regeneration type and manual regeneration DPF. Though automatic type DPF collects PM automatically, the system of intermittent collection-regeneration type is too complicated and continuous collection-regeneration type can be regenerated on the condition of above 250-300 degrees C. emission gas temperature. The manual type DPF is suitable for vehicles of shorter distance and/or lower speed operation in urban area though filter regeneration is done manually. Also, this type DPF is recognized as the necessary system for in-use vehicle with diesel engine. ====================================================================== Editor: Chisachi Kato, International Affairs Committee Published by The Japan Society of Mechanical Engineers Shinanomachi-Rengakan Bldg, Shinanomachi 35, Shinjuku-ku, Tokyo 160-0016, Japan FAX : 81-3-5360-3508 All Rights Reserved, Copyright C 2003 The Japan Society of Mechanical Engineers URL:http//www.jsme.or.jp/English/
