After Bosch has stabilized its share of the domestic diesel engine market and its mainstream common rail technology line has become the mainstay, the next step will be to promote natural gas technologies in the domestic market based on the new characteristics of the changes in the Chinese market environment and the diversification of national energy strategies.
The reporter noted that at the 12th China International Internal Combustion Engines & Components Exhibition and the 2013 China International Auto Parts Exhibition held in Beijing in September, Bosch Diesel demonstrated the use of single fuel for natural gas vehicles. Natural gas system of diesel-natural gas dual fuel power system. According to the relevant person in charge of Bosch, the single fuel system can meet Euro VI emission standards in the use of post-processing systems, while the dual-fuel system is improved on the diesel engine to enable ignition and ignition like diesel engines. And it mainly consumes natural gas to work.
Mr. Wang Weiliang, President of Bosch Diesel Systems Division China and General Manager of Bosch Automotive Diesel Systems Co., Ltd., told reporters that the first mass production project of Bosch natural gas technology, which was defined as a new-generation natural gas engine, was developed at Weichai WP10. The project is in cooperation with Weichai and is expected to reach mass production next year; the localization team and related facilities in China will also be completed by the end of this year; several Bosch natural gas technology projects have been negotiating or expanding with many domestic OEMs. .
From the development history of Bosch natural gas technology, it can be seen that in 1998, the first spark plug ignition natural gas engine equipped with Bosch system was listed in Europe; in 2006, Bosch Brazil Company developed dual fuel natural gas technology; in 2008, with foreign engines The single-fuel spark plug ignition type natural gas engine equipped with the Bosch system that entered the Chinese market was launched into the Chinese market. In recent years, Bosch has further consolidated its single-fuel and dual-fuel natural gas system platforms, and the natural gas engines of the two systems have achieved mass production matching worldwide.
Low emissions, low energy consumption, low fuel costs, low noise, and the advantages of natural gas vehicles Needless to say. In fact, optimistic about the Chinese market and dare to invest boldly is based on Bosch's overall judgment of China's natural gas vehicle market. In an information provided by Bosch, from 2010 to 2015, China's natural gas supply capacity, import volume, pipeline transportation capacity, new natural gas reserves, etc. will all have large-scale development. This has also formed the basic judgment of Bosch. The application of natural gas in the Chinese automotive sector will be listed as a priority development. In particular, compared with the proportion structure of foreign natural gas vehicles, the current medium and heavy-duty natural gas commercial vehicles, including trucks and buses, have become the dominant direction for the Chinese market. The market research company predicts that the compound average annual growth rate of medium- and heavy-duty natural gas commercial vehicles in China will be as high as 26% between 2012 and 2017. And seeing that China will implement a more diversified national energy strategy in the future, it can be said that it is Bosch's major policy support to attack the natural gas market.
For most of the domestic medium- and heavy-duty diesel manufacturers have already involved in the natural gas engine field, Wang Weiliang said that Bosch's natural gas technology is the world's leading, the entire system is very mature, and many domestic manufacturers have already found Bosch, hoping to have diesel and Bosch, the dual core technology of natural gas, integrates new natural gas systems. Mature technologies, ready-made parts and spare parts, and existing foreign market experience, these combined advantages have also made Bosch earnestly involved in preparation and timely intervention. Following the diesel system, the attitude of rushing natural gas engines in the Chinese market has been revealed.
From the analysis of technology, efficiency, and life-cycle output, Wang Weiliang is more inclined to develop diesel and natural gas dual-fuel engines. His reasons are as follows: First, because it is compression ignition, the efficiency will be more like that of a diesel engine, and the diesel engine will save 30% of fuel compared with a gasoline engine. Second, the dependence of the natural gas infrastructure is small, and the city-wide and urban workers In addition, natural gas can be burned more than necessary. In regions where natural gas is difficult to fill, it can burn more or even burn 100% diesel. Third, as the reliability of vehicles increases, the used car market for commercial vehicles like passenger cars will also appear. After the dual-fuel vehicles are used in the cities to a certain extent, they are sold to rural areas through the used car market, and can also be used in accordance with a qualified diesel car. Therefore, the dual-fuel engine product has an advantage over the entire life cycle.
Wang Weiliang believes that from an efficiency point of view, if the dual-fuel engine uses 80% of natural gas and 90% of natural gas, the fuel economy will be 10% to 15% higher than that of similar diesel engines. On the basis of many advantages of natural gas engines, this can be said to be one of the greatest benefits for many domestic transporters.
