Torque Limit? Flameout? Low Ash Engine Oil Saves Your Aftertreatment

Torque Limit Flameout Low Ash Engine Oil Saves Your Aftertreatment

In the era of National VI, “torque limitation”, “no power” and “stalling” have become hot topics among truckers. Because of the higher emission limit of the national six truck, its aftertreatment is also more precise. Therefore, the aftertreatment problem, the vehicle will naturally limit the speed and torque, resulting in the vehicle “no energy”, and even “stall”.

What is the speed limit? Which part is wrong?

Many of today’s trucks are equipped with an aftertreatment particulate filter, or DPF (diesel particulate filter). It is like the filter pads in a vacuum cleaner and collects soot, toner and other particles from the engine exhaust.

Many of today's trucks are equipped with an aftertreatment particulate filter, or DPF (diesel particulate filter). It is like the filter pads in a vacuum cleaner and collects soot, toner and other particles from the engine exhaust.

Once the sooty toner has been completely collected, the vehicle needs to be regenerated with DPF. Whether it is passive regeneration while driving or active regeneration after stopping, the carbon powder is burned up by high temperature and converted into carbon dioxide and expelled from the vehicle. If the exhaust gas is not cleaned, the DPF will be clogged over time and the vehicle will be speed and torque limited or the engine will “bog down” due to poor exhaust. Therefore, the speed limitation and torque limitation of the vehicle could be the problem of the DPF.

Where does DPF blockage start? Why doesn't regeneration work?

Under normal conditions, the carbon ash produced by diesel engine combustion will accumulate in the DPF. When the vehicle is running at high speed, the high temperature exhaust of the engine will cause the carbon ash to burn into carbon dioxide. In the case of ineffective passive regeneration, the vehicle can be taken in place with the engine running at high speed, thus raising the exhaust temperature and cleaning up the carbon ash. However, there is one type of particulate matter in the exhaust that has no effect on DPF regeneration.

To ensure longer life and better working results, the inside of today’s engines’ cylinders will be honed. During the honing process, a fine mesh pattern is etched on the inside of the cylinder. These webs are designed to retain oil and improve lubrication performance.

When the cylinder burns, the oil in the net structure will be instantly heated and burned, and this part of the oil may produce some ash particles, which will be exhausted with the exhaust gas. As truckers know, there are base oil and additives in the composition of engine oil, and these additives inevitably contain some metallic components, which will also lead to ash from oil combustion. Some of them cannot be treated by combustion, and these components can only be treated in post-treatment.

How to solve the post-treatment blockage?

Faced with the DPF clogging caused by this situation, normally, we can only choose to replace the DPF or manually disassemble and clean it. But as the saying goes, “prevention is better than cure”, early prevention is better than early remedy. In fact, in the process of vehicle maintenance, as long as a little attention, you can greatly reduce or even avoid the problem of post-treatment clogging.

The solution is very simple. where does the ash in the DPF come from and we will fix it. Using a low ash engine oil will undoubtedly reduce the production of soot in the exhaust and reduce the clogging of the DPF. This is also highly recommended by many manufacturers.

When it comes to motor oil, I believe that everyone has a yellow shell logo in their mind. Yes, the shell that gives most people the first impression of motor oil is also available as shell Duracell ck-4 motor oil suitable for use in trucks in the fifth and sixth countries. Moreover, this motor oil also uses a fully synthetic base oil and a low sulfur, low phosphorus and low ash formula

Take Shell Duracell K10 engine oil as an example. This engine oil uses a fully synthetic base oil and a low sulfur, low phosphorus and low ash formulation. How do you understand these formulations? With low sulfur content, the engine oil is less likely to acidify prematurely and its protection cycle and protection capacity will be longer. Likewise, phosphorus may cause corresponding problems.

How do you understand these formulations With low sulfur content, the engine oil is less likely to acidify prematurely and its protection cycle and protection capacity will be longer. Likewise, phosphorus may cause corresponding problems.

In addition, the most important thing is the low ash formulation. Engine oils with low-ash formulations produce less ash during combustion, which results in less non-combustible ash entering the DPF. In this way, our DPF is less prone to problems. In addition, Shell Gold Bar fully synthetic ck-4 engine oil is compatible with National V vehicles, giving better engine protection and a more practical 100,000 km oil change mileage.

● Postscript
The official implementation of the national six standard has entered the countdown stage. In fact, as long as we take care of the national six standard, it is not terrible. And careful maintenance, first of all, requires good motor oil. Shell Duracell ck-4 motor oil is a rare and good choice.
