Gap between Made in China and international leading technology in turbocharger

Gap in R&D capability. The performance of the engine is required to be further improved. At present, the emission regulations of my country's automotive diesel engines are in the stage of National IV and V, and the emission regulations of non-road diesel engines are also in the stage of National IV. Generally, after-treatment devices such as EGR, SCR, DOC and DPF are added after the exhaust gas turbine (30, 31). From another point of view, these devices must increase the Exhaust  pressure of the cylinder and affect the indicated thermal efficiency. An effective compensation method is to increase the pressure ratio of the turbocharger. In addition, automotive engines, whether diesel, gasoline or natural gas, must improve their responsiveness in order to meet the emission regulations of National III or above, so the turbocharger must be miniaturized. Vehicle engines have a wide variation threshold of air flow, especially gasoline engines, which require the matching compressor to also have a wide high-efficiency area. Because of this, turbochargers are developing in the direction of high pressure ratio, high speed, high efficiency and light weight, and new supercharging systems such as two-stage supercharging, variable section supercharging, electric auxiliary supercharging, and sequential supercharging continue to appear , and has been fully developed. Made in china T/C is still far to meet this requirement.

The Made in china T/C industry that produces turbochargers is undergoing institutional reform. The development of national enterprises on a difficult and tortuous road into the rapid development of the period since the turbocharger and turbocharger parts of the production plant like a mushrooming. But most of the factories due to small scale, lack of funds, backward technology, quality out of control, and ultimately just a "flash in the pan". In this period of "mass movement", the growth of national enterprises are also facing the challenges of technology, talent, capital and market. And the momentum of specialized production is becoming increasingly apparent, large and complete production model has not adapted, in order to improve product quality, improve market competitiveness, the domestic pressure booster enterprises need to carry out institutional reform, in order to better align with the international market.

Lack of localized brands. Foreign enterprises strong control of the distribution market from the 1980s, the UK Holset, the United States Honeywell, Japan IHI and Mitsubishi Heavy Industries, Germany KKK, the United States Borg-Warner and other foreign enterprises were set up in China as wholly-owned, joint ventures and other ways to booster production institutions. These supercharger giants have advanced design, manufacturing capabilities; products with reasonable structure, high flow efficiency, reliable work, deep user trust, has controlled 90% of the global supercharger market. At present, attention to product reliability has become increasingly important to the decision-making groups of national industry. But the constant renewal of foreign supercharger brands also urged domestic superchargers to develop their own products, improve matching technology, and gradually create a localized Chinese turbocharger brand.
