China first meet euro VI diesel engine was born in Yulin

China first Euro VI vehicle with diesel engine, Yuchai 6L-60 Euro VI prototype in Yuchai power Plaza debut, opened a new chapter in the history of Chinese internal combustion engine research and development.

Yuchai group board of directors chairman Yan Ping, national car quality supervision and Inspection Center (Tianjin Automotive Test Center), deputy director of the history of permanent million, Tianjin university internal combustion engine combustion science, State Key Laboratory Director Yao Ming FA, Yuchai Machinery Co., Ltd. General Manager Wu Qiwei together opened a red silk, demonstrating China's first Taiwan EU VI vehicle diesel engine to the world.

This is the 60 anniversary of Yuchai 90 birthday party, Yuchai a gift offering of the plant!

Tianjin vehicle inspection center announced the inspection report on the morning of June 29th held a press conference on yuchai. The report shows that the engine nitrogen oxide (NOx) emissions of 307.3mg/kW.h, particulate emissions 6.5mg/kW.h, far lower than the limit of the European VI emissions requirements, fully comply with the EU VI emission regulations. And the euro VI emission regulations, EU to release in 2009 of the world's most stringent vehicle emission regulations of, is known in the industry as the "ultimate" emissions regulations, in line with the regulations of the engine exhaust emissions "even than the air is clean". The EU plans to start in 2013, most of the European car engine companies are in the product development phase. In this time to publish the first Euro VI cars in China diesel engine, marking the Yuchai has the independent development ability of development and international synchronized, clean diesel engine, and master the most advanced diesel engine combustion core technology.

To this end, Yuchai and R & D personnel of Tianjin University made unremitting efforts. They used only four years time in conquering the euro VI diesel multiple key technical problems, such as two-stage turbocharging technology, cooled exhaust gas recirculation technology, low-temperature combustion technology and aiding DPF regeneration control strategy. The guests called "Yuchai pride, but also the pride of the China internal combustion engine industry".

Wu Qiwei said, for the pursuit of "green development, harmonious and win-win", determined to do "the biggest event of a pollution source" control of Yuchai, Euro VI engine research and development success is just a starting point.

Since the factory was founded 60 years, Yuchai engine, high reliability, low emissions technology research and development, creating a a lot of "world first" and "China's first". As early as 2006 and 2007 for two consecutive years, Yuchai first developed the equivalent of Euro IV and euro V standard in 4, 5 in the engine. In 2010, Yuchai international first proposed moderate EGR diesel low temperature combustion technology route, established the independent, clean diesel technology strategy. The same year, China's first production by Yuchai engine in 5 mass market.

After a lapse of one year, Yuchai and a walk in the forefront of the industry, first introduced the euro VI diesel engine fill the blank of clean and efficient diesel engines in China, to enhance the level of technology of national research and development of high grade engine emissions, become another milestone in the development history of the engine.

At the press conference held after the news media collective interview, Shi Yongwan, Yao Ming hair and President of Yuchai company chief engineer Shen Jie, Yuchai Engineering Research Institute Lin Zhiqiang experts to reporters are introduced in detail this euro VI diesel engine technology advantage. Experts said, compared with the current European products, diesel engine has three technical highlights of the release of the European car Yuchai VI: one is to adopt a completely independent intellectual property rights of low temperature combustion technology route, reduce the injection pressure, fuel injection pressure is lower than the European system of similar products at present common rail fuel injection, improve the core components of the fuel injection system of life; two is the use of moderate cooling exhaust gas recirculation (EGR) technology, the high pressure common rail fuel injection control system of multiple injection strategies, to achieve efficient and clean burning, even without the original emission treatment after final treatment system has also been close to euro V emission level; three is the use of selective reduction SCR technology and for particulate filter regeneration, after treatment system of urea consumption is only half of the 4 diesel engine, greatly reducing the cost, convenient for users, reduces the dependence on the construction of urea adding device.

The engine core technology research "the water rose", will drive the engine full range of product development "boat high". The core technology with independent intellectual property rights will be re upgrade to provide adequate technical reserves for Yuchai series products.

Yuchai again by leading technology, to attract the attention of the world.

People's daily, Xinhua news agency, Central Television, Guangming Daily, economic daily, worker's daily, China News Agency, science and technology daily, Hong Kong Wen Wei Po, China industry news and China Automotive News and other 28 major media focused the Chinese engine industry event.
