Where is the road for domestic electronic fuel injection excavators?

Due to the use of electronic fuel injection in the development of new products by many excavator brands, and based on recent market reactions. It seems that electronic fuel injection excavators are not suitable for China. What is the reason?

Firstly, the biggest reason is that the quality of domestic diesel is not good, and electronic fuel injection engines have higher requirements for fuel than ordinary mechanical high-pressure fuel pumps. Strict control is also required over the quality and replacement cycle of the filter. Especially in recent timesHitachiThe electronic fuel injection series has been frequently complained by users, and the Komatsu-8 series also has many problems. Secondly, domestic users have a strong dependence on direct injection excavators. Not very mature in terms of corresponding repairs and maintenance. Users do not know how to use the electronic fuel injection series well, which requires high maintenance and upkeep awareness of the machine for operators, while those who work in engineering are generally "reckless". I don't know much about it, once there is a problem, I have to find a repair shop. And when dealing with electronic fuel injection faults, the repairman only suggests using higher quality diesel. And neglect the daily maintenance of excavators.

Obviously, electronic fuel injection is a trend, and I believe it will be in the near future. There will definitely be more mature technologies to properly address this compatibility issue.
