Since the beginning of this year, with the upgrade of diesel vehicle emissions and the implementation of non-road diesel engine T3 emission standards, domestic independent brands of high-pressure common rail have made major breakthroughs in market promotion and related technologies have also been improved. Xinfeng Technology's high-pressure common rail products are expected to sell more than 100,000 units this year; ASIMCO Tianwei non-road high-pressure common rail products are sold 2,000 units per month, and there are more than 30 cooperation projects. At the same time, independent high-pressure common rail companies are actively promoting the research and development of National V and VI technologies for vehicles, and have made breakthroughs in pursuit of the international advanced level.
