For a car, why is the engine speed limited during normal operation? After the speed is limited, the engine torque can’t come up, so don’t think about the speed of god horse the poor filter. In fact, many times, some vehicle faults can be avoided, but they cause more trouble because of the desire to save trouble.
Engine speed limit due to insufficient oil pressure
In the past, the symptom of this car was that after the car ran, no matter how much the accelerator was pressed, the speed was capped at 1800 rpm. Initially, kayou judged that it might be the fault of the common rail system, resulting in insufficient oil pressure. Of course, there are many reasons for insufficient oil pressure, which may not be all.
After being overhauled by professional maintenance masters, they soon denied the saying of common rail system failure. The first step is to check the oil-water separator.the poor filter The rubber gasket on the top has been aged, which has brought a lot of trouble during disassembly.
Through actual inspection, it is found that the filter elements of the three auxiliary plants on the vehicle have almost been completely blocked, and the inferior oil-water separator can not effectively separate diesel and water, so that the poured diesel has become milky white and rich in a large amount of emulsion. It can hardly be used again, so we have to replace the new three filters.
The oil pump is blocked and the oil supply is insufficient the poor filter
Since the poured diesel oil is milky white, there must be some problems with the oil itself. The little master who repaired the oil pump was really stunned after he took it apart. The pump port of the oil pump has almost been blocked by a large number of impurities. It is almost difficult for the oil pump to ensure the normal oil supply of the engine during the normal operation of the vehicle.
In addition, the previous oil-water separator and diesel filter element are seriously blocked, and the diesel flow in the whole oil circuit is actually very small. In this case,the poor filter can only start, and it is almost impossible to achieve greater performance.
As the maintenance personnel were called temporarily, they only judged that it was the problem of diesel filter element at the beginning,the poor filter and did not consider that the oil pump would be blocked so seriously, so they had to rely on on on-site tools to temporarily clean the oil pump. Fortunately, after cleaning the oil pump and replacing the genuine filter element, the problem of limiting the speed of the engine was finally solved.
Genuine filter element ensures oil circuit safety
Many card users think that as long as the filter is almost OK, there is no need to pursue high-quality products. But when you really encounter a problem with the filter element and ask the service station to repair it when it comes, the poor filter the money you may pay is far more than the money you save by buying a low-quality filter element.
The use of genuine diesel filter can effectively the poor filter the fine impurities and moisture in diesel, so as to protect the parts such as oil pump nozzle and piston ring from wear and blockage, and filter out a series of trace components such as iron oxide in diesel.
In the mall of truck house, you can buy genuine Parker filter element, which can almost perfectly match most commercial vehicles on the market. The price is more than 100 points. You deserve it.
I think everyone knows more or less about the harm of poor quality filters. Good products must have advantages, so card friends should not be greedy for a temporary small price when buying and choosing these important automobile products, so as to “hurt” the car.
The loss outweighs the gain will affect efficiency and waste money. the poor filteris suggested that some vulnerable parts on the car should be purchased through formal channels.
