Modern engines require better fuel quality, which requires better filters to filter impurities. But many people's understanding of the filter is still very incomplete, if not correctly maintained, may cause very serious problems. Netizens summed up a few erroneous knowledge about filters. Let's take a look.
Fallacy 1: "filters, as long as cheap, can be properly installed on the engine."
Fact 1: Many filter manufacturers in China simply copy and imitate the geometric size and appearance of the original parts, and pay little attention to the engineering standards that the filters should meet, even do not understand the content of the engineering standards. The filter is designed to protect the engine system. If the filter performance can not meet the technical requirements and lose the filtering effect, then the performance of the engine will be significantly reduced, and shorten the service life of the engine. For example, the life of a diesel engine is directly related to the 110-230 grams of dust that the engine "eats" before it is damaged. Therefore, inefficient and inferior air filtration will cause more impurities to enter your engine system, causing your engine to overhaul in advance.
Fallacy 2: "if I don't have to change the filter regularly, then this filter is definitely good."
Fact 2: The function of the filter is to filter out the dust and impurities in the air, oil, fuel and coolant so that these impurities are removed from the engine and the engine system is protected. High quality and high efficiency filter can capture more impurities than inefficient filter. If the ash capacity of the two filters is the same, it is obvious that the replacement frequency of high quality and efficient filters will be higher. Most of the filters sold on the market are short-circuited (impurities are not filtered directly into the engine system). The reasons for short-circuiting are perforation of filter paper, lack of bonding between the end and end of filter paper, and poor bonding between filter paper and end cover. If you use such a filter, you will be in a long, long time, or even do not need to replace it for life. Because it has no filtering function at all. Therefore, the above view is wrong.
Fallacy 3: "I don't think the filters I use cause me any trouble, so I don't have to spend more money on quality filters."
Fact 3: The impact of inefficient filters on the engine may or may not be immediately visible. The engine seems to be working very well, but harmful impurities may have already entered your engine system and started to cause engine parts corrosion, rust, wear and tear. These damages are hidden and will break out when the damage is accumulated to a certain extent. So, although you can't see any signs now, it doesn't mean that the problem does not exist. Like a hidden time bomb. Once you find a problem, it may be too late, and you will have to spend a lot of money to repair your engine. Therefore, stick to the use of high quality guaranteed filters to maximize the protection of your engine.
Fallacy 4: "My engine is old and out of warranty, so there's no need to use high quality filters."
Fact 4: old engines are easier to wear and cause to pull cylinders. As a result, older engines require high-quality filters to stabilize escalating wear and tear and maintain engine performance. Otherwise, you will have to spend a lot of money on maintenance, or you will have to scrap your engine in advance.
Fallacy 5: "the quality of the filter I purchased is a bit poor, but I often change, so there should be no problem.."
Fact 5: The measure of filter quality is not only the filter life, but also the filter efficiency. High quality filters should be of high filtration efficiency and longer service life. Therefore, the manufacturers of positive filters should fully consider the performance indicators of the filter when designing the filter. Many filters on the market are simply copied and imitated from the original parts, and their performances mostly do not meet the requirements of engine manufacturers'technical engineering standards.
After dissecting, analyzing and testing the market brand filters, the results are shocking: serious leakage and short circuit exist at the end-to-end folding bond of the internal filter element or the bond between the filter paper and the end cover. If you buy a filter that doesn't filter, it won't protect your engine effectively even if it's often replaced.
Through the clarification of the above errors, we hope you will realize that it is inaccurate to evaluate the quality of the filter only by looking at its appearance. Many domestic filter manufacturers pay more attention to the appearance of the filter and ignore its performance and quality, which is not desirable.
