On July 1, 2023, Phase 6b of the National VI emission standard will be fully implemented nationwide. From the technical route point of view, China VI ab is basically the same, or divided into EGR technical route and non-EGR technical route, so how to achieve further upgrades? The main thing is the oil.
The normal operation of the National VI engine requires a sulfur content of less than 10ppm for diesel, and there are also certain requirements for the cleanliness of the oil. There are also certain differences between the sixth and fifth grade oil products, with the sixth grade oil having higher quality and producing less exhaust gas during combustion. Therefore, Guoliu Oil is more suitable for Guoliu vehicles.
In daily transportation, it is also necessary to maintain according to the time or mileage specified in the maintenance manual, and go to a qualified service station for maintenance, especially for air filters, diesel filters, etc., which also have certain requirements. In addition, if the vehicle frequently enters and exits complex working conditions with a lot of dust, in order to ensure the intake effect, it is also necessary to pay attention to inspecting and promptly cleaning the intake pipeline.
Although most vehicles in China are equipped with an active regeneration function for post-treatment, when there is too much carbon accumulation in the post-treatment, the vehicle will undergo active regeneration while parked. However, active regeneration cannot solve all the ash content in the post-treatment system, as it accumulates over time and requires cleaning at a service station.
