Electronically Controlled Gasoline Injection System Industry Market Characteristics TOP4

The electronically controlled gasoline injection system (EFI) is an electronic control unit (ECU) as the control center, and uses various sensors installed on the engine to measure various operating parameters of the engine, and then precisely control according to the pre-stored control program in the computer. The fuel injection amount of the injector enables the engine to obtain the best air-fuel ratio combustible mixture under various working conditions to achieve the best air-fuel ratio.

At present, the market of EFI systems mainly has the following characteristics:

1. The EFI system is based on its ecu, so the technology is almost monopolized by foreign capital. As a result of the upgrade of emission standards by independent brands, the cost of new models that meet the emission standards is increased, and the speed of delivery is behind the joint venture brand. When the state upgrades the vehicle emission standards, it is easy for foreign-funded enterprises to transplant mature models and related technologies sold abroad to the country without any technical difficulty and cost. Self-owned brand vehicles need to re-calibrate and test the ECU. Because they do not lack core technology and experience, they have to resort to foreign-funded enterprises, which will cost a lot of money.

2. The EFI system is divided into gasoline EFI and diesel EFI. At present, the popularization of gasoline EFI technology is relatively high, while diesel EFI is controlled by Bosch, the mainland, Japan's Denso and the United States' Delphi, as well as the domestic market.

3. From the perspective of market share, Bosch has a market share of about 60% of China's EFI system, and Delphi's market share is also more than 10%. In addition, it is Marelli, Germany, Cummins, etc., while domestic independent EFI companies only Occupy less than 5% of the share. The EFI system has a high barrier to entry, and there are not many domestic independent brand enterprises, and there are fewer large-scale enterprises, so the market share is relatively low.

4. From the perspective of supporting facilities, the European and American enterprises represented by Bosch, Delphi, China, and Marelli are mainly used for European and American models. The Japanese-funded enterprises represented by Denso and Keihin are mainly Japanese. Model matching. And in the diesel EFI market. Shangchai and Xichai mainly use electric products; FAW Dachai and Yuchai mainly use Delphi products; Weichai mainly uses Bosch products.

In addition, Cummins has its own products. Because this is a highly concentrated industry, the competition among enterprises is not as intense as other auto parts industries, so it also leads to a relatively small selection of domestic OEM products, and is also very passive in negotiating with suppliers. It is not a matter of time to change this situation. The OEM can use its own advantages to find some suppliers with certain potential to develop together. In addition, it should encourage the introduction of technology and build its own innovation system through digestion and absorption.
