Starting from parts, China's engine industry will have a promising future

With the continuous development of China's auto industry, the production and sales continue to grow. China’s engine market has also become a “sweet potato” on a global scale. In recent years, both domestic and foreign automobile manufacturers and professional engine manufacturers have increasingly invested in engine research and development to seek a share of the promising Chinese engine market.

So for the direction of the development of the internal combustion engine, Jiang Deming, former president of Xi'an Jiaotong University, standing director of the China Internal Combustion Engine Society and chairman of the Internal Combustion Engines Society of Shaanxi Province, told reporters that domestic companies may pay more attention to German Bosch on diesel engines and BMW on gasoline engines when studying internal combustion engine technology. On the research dynamics. At the same time, he reminded domestic manufacturers and foreign companies that in the research and development of thermal insulation machines and free-piston engines, there were many failures and few successes. Chinese companies could also think more about “wind” at the same time.

Improve fuel economy into general development trend

For more than 100 years, the power source has always been the most important, most scarce and core component of the machinery industry. In the equipment manufacturing industry, whether in the field of aircraft, agricultural machinery, or construction machinery, the main core technologies are concentrated on engine components.

What is the general trend of current engine technology development? Jiang Deming told reporters that emissions are no longer the main issue for the development of internal combustion engines. All emissions issues, including the technical route to solve emissions problems, and post-processing equipment to solve emission problems, are the road to these problems. It is very clear. At present, the focus of attention of all countries has begun to shift to improving fuel economy, namely greenhouse gas CO2 emissions. Since emissions are related to technological energy levels and involve upgrading of the entire power system, foreign companies can be said to have more advantages in these areas. Taking Cummins as an example, the most important reason why the company can succeed is technology leadership. Peng Lixin, vice president of Cummins Global, said that the internal combustion engine to achieve energy-saving requirements, technical capabilities are very important.

It is understood that Cummins has four major technology research and development centers in the world, and the investment in technology research and development every day is more than 2 million US dollars. It can be said that Cummins's emphasis on technology has made it a leader in the industry.

How to develop the internal combustion engine in the future? For this issue, Peng Lixin stated that the emission standards of US internal combustion engines have been difficult to detect after the Euro VI. Therefore, after 2013, the development of internal combustion engines is no longer seeking to reduce emissions for development. The goal is instead to focus on the energy saving of internal combustion engines.

In this regard, it can be said that the HCCI, PCCI, lean-burn engines, and stratified combustion engines that the United States had made great efforts to study have also become old days.

According to official statistics, traditional engines will still dominate the next 10 years; traditional engines will account for 54% in the next 20 years, hybrid engines will account for 30%, and fuel cells will account for 1%; engines and hybrids will still account for more than 70% in the next 40 years. market. Therefore, we can see from the above statistics that we can't give up the use of conventional engines in the future.

In addition, Jiang Deming told reporters that in the field of technological advances, the current variable valve mechanism technology (VVT) has become the standard configuration of high-grade gasoline engines, because it has a significant role in reducing fuel consumption, emissions and improving power performance of internal combustion engines.

Problems and Opportunities

In 2011, the output of internal combustion engines in China exceeded 77 million units, and the total power exceeded the 140 million kilowatts mark, becoming a truly large-scale manufacturing enterprise of internal combustion engines. However, on the whole, there is still a big gap between China's internal combustion engine products and the international advanced level in terms of performance, quality, especially in energy conservation and environmental protection, and reliability.

In particular, the issuance of the Opinions on Strengthening the Energy-saving and Emission-reduction of the Internal Combustion Engine Industry of the General Office of the State Council (referred to as the “Opinion”) has begun to count down the assessment of energy-saving and emission reduction of the entire internal combustion engine industry.

According to the Opinions, by 2015, energy-saving internal combustion engine products will account for 60% of the entire society's internal combustion engine products. Compared with 2010, the fuel consumption rate of internal combustion engines will be reduced by 6% to 10% by 2015, achieving a reduction in commodity fuel consumption 2000. 10,000 tons, reduce CO2 emissions by 62 million tons, reduce nitrogen oxide emissions by 10%, and use alternative fuels to save 15 million tons of commodity fuel. At the same time, a number of key remanufacturing enterprises, such as automobiles and construction machinery engines, will be cultivated to achieve localization and large-scale production of high-efficiency, energy-saving and environmentally-friendly internal combustion engine main engines and their parts and components manufacturing equipment.

Regarding whether this goal can be achieved, people in the industry generally believe that it still has difficult challenges.

In addition to factors such as the increase in raw materials, fuels, power, and labor costs faced by the industry, domestic internal combustion engine companies are also facing the predicament of foreign companies robbing the Chinese market. For this dilemma, Jiang Deming told reporters that the main reasons are domestic and foreign-funded enterprises. Compared to the lack of core competitiveness, domestic companies are reluctant to invest more money in R&D, and their independent intellectual property rights are not protected.

It is undeniable that compared with foreign-funded enterprises, domestic companies do have a big gap with foreign companies in terms of new product development speed, product performance, brand, quality, cost, and after-sales service.

"But these gaps can only be shortened by Chinese companies through hard work." Jiang Deming told reporters that Chinese engines are starting from the high-pressure fuel supply system of diesel engines and various parts and components of direct-injection gasoline engine oil supply systems, as well as exhaust after-treatment systems and turbochargers. China's engine parts are still bigger and stronger. Great promise.
