Since the beginning of this year, “national six” has probably been the most frequent in the circle of friends of card friends. Although we explain what national six is, what benefits it has and how vehicles will meet national six emission standards every day.
But for many card users, they don’t care what national six is, what technical route to use, its working principle, or whether it can be environmentally friendly or how environmentally friendly. Card users may want to know how much more the national six model will cost, what to pay attention to when using it, and how to maintain it during use.
Today, let’s talk about DPF, a small part of the post-treatment of the national six year plan, from the aspects of “what to pay attention to in the process of using the car, how to maintain it and how much the cost will be higher”.
Therefore, after the DPF reaches the maintenance mileage, some maintenance measures can be taken, one is DPF regeneration, the other is DPF ash removal.
Under normal conditions, as long as the exhaust temperature is in the range of 220-440 ℃, the regeneration process can occur naturally without human intervention. However, when the particulate matter accumulates to a certain extent and cannot be handled by itself, it is necessary to manually control the active regeneration. There will be a regeneration button in the car. After it is turned on, the engine will improve the work efficiency and temperature, so as to burn the accumulated particulate matter of Dpf.
Diesel engines burn oil during operation. The oil in the crankcase is transmitted to the oil filter through the oil pump, and most of the oil surfaces on the lubricating surface are Liu Hui crankcase.
Part of it enters the combustion chamber and enters the exhaust system with a barrel of waste gas after combustion. When entering the DPF, due to the large internal resistance, the flow resistance will also increase, and the residue of engine oil will be deposited. Therefore, the quality of engine oil is very important.
Fuel consumption also has an impact on DPF. Under the same conditions, the higher the fuel consumption, the more tail gas to be treated by DPF, and the greater the impact.
1. Use diesel oil with low sulfur content.
2. Use high-quality engine oil.
3. Minimize vehicle fuel consumption.
DPF is only one part of the post-processing of national VI. the minimum three guarantee period for key emission parts of national VI products is 5 years or 160000 km. According to the above data, cleaning basically needs to pay for itself.
Of course, it doesn’t mean that all need 800-1000 yuan. There must be a gap in prices according to different brands and service stations. It should be noted that 800-1000 yuan is only the cost of cleaning. If it is damaged due to improper use, it will be added with the cost of replacement.
Card users should pay attention to the oil recommended by the manufacturer when using it, otherwise they will cry when it is broken. Therefore, it is suggested that we should not be greedy for small and cheap, so as not to cause greater losses for ourselves.
