Bosch diesel technology penetrates into China and sticks to the clean diesel market

In Europe, more than 50% of cars are diesel engines. This proportion is only 1% in China. Bosch is optimistic about the prospects of the Chinese diesel market. They predict that when the market reaches 20 million vehicles, diesel passenger cars will According to a 12% to 15% share.

In 1927, the first diesel injection pump developed by Bosch was successfully put into production. Since then, Bosch's name has been closely linked with the important technological innovation in the diesel field. In 1997, the common-rail system introduced by Bosch strongly promoted the innovation of clean diesel technology and brought diesel vehicles into a new era of “economical, clean and powerful”.

In Europe, more than 50% of cars are diesel engines, which is only 1% in China. In the past two decades, the global energy crisis and environmental problems have prompted the automotive industry to continuously explore cleaner, environmentally friendly and energy-saving solutions. In this process, diesel engines have made crucial progress in technological innovation. Stephan Hoelzl is convinced that Bosch has been developing diesel technology for almost a hundred years. Mature clean diesel technology has obvious advantages in terms of economy, cleanliness and driving comfort, and will effectively promote the process of low carbonization in the Chinese automobile industry.

The general manager of Bosch Automotive Diesel Systems Co., Ltd. (Wuxi), who had just been promoted to China, has been in China for four years. He has witnessed the most rapid development of the Chinese automobile industry in recent years. As for the prospects of the Chinese diesel market, he appears to be quite optimistic and predicts that when the market reaches 20 million vehicles, diesel passenger cars will account for 12% to 15% of the market share.

After he took office, the first major event was to take the lead in launching the nation's largest clean diesel technology tour, including the “mobile display unit” and “experience tour”. The first round of tours will be based on the theme of “Enjoy the 'Cheung's Energy” for a period of six months covering about 20 cities across the country. Hoelzl does not expect immediate results. Touring is more like advertising the society. He hopes to show the public through the tour this widely used low-carbon transportation program in the world, after gradually understanding and accepting diesel cars, they can become an important choice for their daily green travel.

PK mix, electric

On a global scale, increasingly stringent emission standards are being drafted and promulgated - the European Union has set a rigorous standard to reduce carbon emissions from new cars to 95 grams per kilometre by 2020; China is in the 12th Five-Year Plan. Once again, the importance of energy-saving and emission-reduction of vehicles at this stage was pointed out, and the emphasis was placed on promoting the research and development and promotion of energy-saving vehicles and new energy vehicles. With the gradual maturity of the consumer concept, domestic consumers are paying more and more attention to their energy-saving and environmental performance in the process of car purchase.

Dong Jianping, deputy secretary-general of the China Association of Automobile Manufacturers, stated at the launching ceremony of the tour that electric vehicles will be the ultimate solution in the future, but it will not be popularized for a long time. Diesel vehicles are a very good solution and have more than 100 years of history. The technology is very mature. .

Then, in addition, what are the advantages of diesel vehicles compared with electric vehicles and hybrid vehicles that are promising in the industry?

"In terms of existing hybrid energy electric vehicles, diesel vehicles are more environmentally friendly. China's electric vehicles have higher carbon dioxide emissions than diesel vehicles because the actual energy composition varies from country to country," Hoelzl told reporters.

As early as 1984, Bosch signed a production license agreement with Weifu, which opened the process of Bosch diesel system entering the Chinese market. In 1995, Bosch and Weifu's first joint venture company, Wuxi Eurasian Diesel Injection Co., Ltd. was established to manufacture and sell mechanical fuel injection equipment in China. In July 2004, the cooperation between the two parties was further deepened: Bosch and Weifu Group jointly invested in the establishment of Bosch Automotive Diesel Systems Co., Ltd., dedicated to the development, matching and production of modern diesel injection technology.

In the existing common rail technology, modularity is one of its biggest features. Through modular technology, common rail systems can be selected based on indicators such as various power segments to update parameters and components to meet emission upgrade and fuel consumption regulations.

Compared with gasoline vehicles of the same class, diesel vehicles equipped with Bosch's advanced technology can reduce fuel consumption by 30%, reduce carbon dioxide emissions by 25%, and increase torque by 50%. In order to adapt to the extremely rapid changes in the Chinese market, rigorous Germans also have to use Chinese-style thinking for product development and integration. Originally, it took 2.5 to 3 years for the application development cycle in Europe. At present, it is possible to match one project in China at least six months. This is a great innovation for Bosch.

hold fast

Compared with Bosch, which occupies 70% of the German market for passenger cars with diesel technology, it has encountered considerable block in China. Prior to this, Volkswagen, which had been promoting diesel technology, was unable to incite prejudice against China’s policy to develop diesel technology. After that, Volkswagen chose to bypass it – on the basis of the gasoline engine, “TSI+DSG” technology innovation was used to combat oil prices. The continued high fever.

In this way, the road to Bosch's diesel technology appears desperate, but they are still looking forward to the future and stick to the diesel market.

Europe is currently implementing Euro V and Euro VI emission standards. In order to meet more stringent emission standards, all auto companies are reducing the use of gasoline engines. In China, they are still in their infancy and will focus on the development of the Chinese market according to Bosch's strategic plan. In four aspects, one is the SUV, the second is the MPV, the third is the taxi market, and there is the micro-market.

Currently, Bosch and some domestic OEMs jointly develop diesel passenger cars. Chery's Weilin V5, Weilin H5, Weilin X5 and Karry Youyou are the most eye-catching; there are Geely's Emgrand EX7, Jianghuai's Ruiying D19TCI, Jiangling's Landwind X8, and Quansheng. , Huatai's B112.0L diesel, Santa Fe 2.0 diesel 4AT, Dongfeng Liuzhou's popular Lingzhi Diesel, Gui's GS-2 Xinchaishen, and Audi's Q7V12TDI, Q52.0T and Mercedes-Benz Weiting VI. TO is powered by diesel engines and is equipped with common rail diesel injection systems from Bosch.

"There are still many projects underway." Wang Xiaodong, deputy general manager of Bosch Automotive Diesel Systems Co., Ltd., said that the ultimate goal of Bosch is to collaborate through these projects to make diesel products go to the market and allow users to feel that "this is the diesel engine." .

In this tour of China, the "mobile display unit" is an original exhibition form that presents clean diesel technology to automakers and research institutes. The "Mobile Display Unit" demonstrates various aspects of clean diesel technology through different functional areas, from multiple perspectives - from the development of diesel engines for more than a century, to the current cutting-edge diesel technology and its future trends, and through multimedia technology. Present and explain the multiple benefits of clean diesel technology.

"Through promotion, consumers will slowly perceive and accept diesel engines after they are involved in use," Wang Xiaodong said.
