在这样尴尬现状的背后,我们不能寄希望于跨国零部件企业放弃垄断地位,能够改变现状的惟有坚定支持国内零部件企业走自主研发道路。事实上,国内已经有零部件企业初步开发出类似的系统。这一点,国内很多发动机企业并非不知情。但是,它们觉得与国外成熟产品相比,国内的产品实在“难担重任”——生产一致性、环保一致性都不理想,还无法保证其稳定性。因此,一些企 Behind such an awkward situation, we can not pin our hopes on giving up the monopolistic position of multinational components and parts enterprises and only being able to change the status quo. We firmly support the domestic parts and components enterprises to take the independent research and development path. In fact, some domestic parts companies have initially developed a similar system. This point, many domestic engine companies are not without knowledge. However, they think that compared with the mature products in other countries, the domestic products are indeed “hard to bear” - their consistency of production and environmental consistency are not satisfactory, and their stability can not be guaranteed. Therefore, some enterprises
