On October 21st, the 8th China International Internal Combustion Engine Exhibition was held at the Beijing New International Exhibition Center. More than 160 domestic engine manufacturers and component companies participated in the exhibition.

According to a cursory statistics, a total of 80 commercial and non-road vehicle engines were exhibited at the exhibition. Among them, Cummins was the most exhibited product, bringing with it all the joint venture companies in the country, bringing with them 11 types of automotive engine products. In addition, domestic companies such as Weichai, Yuchai, FAW Xichai, Deutz FAW Diesel, CNHTC Hangfa, Shanghai Shangchao, Chaochai, Revo Power, Shanghai Hino and other domestic companies also brought a full range of national III, even national IV products. Come to the exhibition.

Not only did domestic mainstream companies come to join in, but in addition to Cummins, Japan's Mitsubishi, Isuzu and other foreign engine companies also brought new products and flagship products. Some foreign parts manufacturers even came to the exhibition to find business opportunities.

State III becomes the mainstream country IV, national V exhibition strength

In this exhibition, the products of State III have become star products of all engine manufacturers. Yuchai, Deutz FAW Diesel, FAW Xichai, CNHTC Hangzhou and other companies have brought the State III engine products. A staff member at the Yuchai booth told reporters that through this exhibition, on the one hand, the company's own strength is displayed; on the other hand, more vehicle companies and users are expected to understand Yuchai products.

In addition to the main products of the State III, there are also many engine products with higher emission standards. At Weichai Power and Cummins booth, the National IV and National V engine exhibits attracted a large number of visitors. Weichai Power's staff told reporters that this show saw Weichai bring two of the Blue Engine series of the National V engine, in order to demonstrate the company's technical strength and enhance the industry's influence.

High pressure common rail, single pump, EGR three world

The National III engine demonstrated at this exhibition can be said to include all the national III national technology routes. The most popular one is the electronically controlled high pressure common rail technology. The exhibitors almost all exhibit high pressure common rail engines. An exhibitor’s staff member said that from the international perspective, the high pressure common rail is definitely the mainstream technology route, but because domestic companies do not have the core technology of the common rail system, the cost is relatively high, but from the future From the perspective of the upgrade of high emission standards, the advantages of high pressure common rails are obvious.

Single pump technology and in-line pump + EGR technology have also been fully demonstrated at the show. Among the companies that have taken the monomer pump technology route, the most prominent is Deutz FAW Dachai. According to the company’s staff, Deutz FAW Diesel has introduced Deutz’s engine production technology, and Deutz’s own monomer pump technology is very mature. Therefore, Deutz FAW Dachai’s National III products are also more choices. Technical route.

Heavy-duty trucks Hangfa is a representative of the in-line pump + EGR technology. This year's WD615EGR engine that entered the country III market with EGR technology received special attention from visitors. Some foreign visitors and university researchers are in front of this engine to find out about the EGR III engine.

National IV engine SCR becomes mainstream

A total of 20 National IV and National V engines were exhibited at the exhibition. The reporter found that most domestic companies tend to take the SCR route, and only Shanghai Hino is pushing the EGR route. Deutz FAW Dachai's technical staff gave an analysis to the reporter. At present, most domestic companies adopt SCR technology to upgrade to the national IV standard. The main consideration is to adopt the EGR technology, which will lead to increased fuel consumption and increase the cost of use.

The technicians of Hino in Shanghai stated that Hino was the main EGR route in Japan. At that time, it was mainly considered that there were not many sites for urea filling in Japan. From the actual situation, although the fuel consumption of the engine using the EGR technology will increase, but the engine using SCR technology also needs to regularly add urea as a catalyst, but also requires a certain amount of overhead, compared to the user's use costs are similar.

It is understood that Beijing Public Transport has taken the lead in using the National IV engine and has also built a corresponding urea filling station. The technician said that Hino will also develop the National IV engine using SCR technology to meet the future demand of the Chinese market.

Parts companies find markets

Unlike engine companies that display products and their technical strengths, the demands of exhibitors from other parts and components are more realistic. They hope to win the attention and favor of the engine plant at the exhibition and lay the foundation for future cooperation.

At this exhibition, parts manufacturers will be more focused on key components needed for engine emission upgrades. Bosch, Isuzu and other foreign companies have come up with their own sophisticated electronically controlled common rail fuel injection systems and hope to cooperate with more domestic manufacturers. In addition, a large number of companies have positioned their products in the China IV component market, and various domestic and foreign catalysts and SCR processing exhibitions have become key products on display.

Domestic high-pressure common rail mass production next year

As soon as he entered the new International Exhibition Hall W3, the reporter first saw the booth of the FAW Wuxi Fuel Injection Equipment Institute and a set of self-produced electronically controlled common-rail injection systems. Engineers from the FAW Wuxi Fuel Pump Institute told the reporter that at present, their independently developed electronically controlled common-rail fuel injection system has been actually tested on buses in Shanghai, Wuxi, and other cities and FAW Jiefang Trucks. It is expected that by the end of 2009, this The product can achieve mass production.

But when it comes to the scale of production, the engineer said that from experiment to production, plant construction is needed and a lot of manufacturing equipment needs to be purchased. Funding is the biggest problem they face. "If our production capacity is to meet the needs of companies that produce tens of thousands of engines for FAW Xichai, investment will cost at least 1 billion yuan," he said.
