Paper or synthetic? What filter does a turbo engine need?

Filters weren’t always


The job of a filter is not to obstruct air or fuel flow and trap harmful impurities as much as possible. The targets are multidirectional, but modern filters can handle them.

Having created the internal combustion engine, a person did not immediately realize the need for filtration. Even the most massive Ford Model T cars and “American trucks” did for years without such key elements. Despite the fact that the first oil filter was patented as early as 1923 by the American inventors Ernest Sweetland and George Ginhald. Their system cleaned only a tenth of the engine oil, yet the engine life increased several times.

That is why air, fuel and oil filters were quickly introduced en masse, even on cheap cars.

Oil is cleaned with paper

Despite advanced technology and scientific achievements, absolutely all modern oil filters are made of paper (we are talking about the filter material, of course). True, the paper in it is not easy. It is made of special woods, impregnated with high-tech compounds and withstands high thermal and mechanical loads inherent in modern engines.

Besides, only a few factories make filter paper for the whole world.

Important valves

Each filter is equipped with two valves: bypass and anti-drain. If the oil filter is not separable, the valves are built into the housing. Where the oil filters the cartridge, the valves are an integral part of the cleaning system.

The bypass is used for emergency relief of overpressure that can develop in the line when the filter element is heavily clogged. In this case, the oil will bypass the filter and not be cleaned. Therefore, it is better to replace the filters in time.

If the bypass valve fails, increased oil pressure can breach the filter barrier, allowing accumulated debris to enter the engine along with filter debris.

Otherwise, due to valve failure, oil will circulate in the system with insufficient pressure. how the result – oil starvation and expensive repairs.

Continuous lubrication

The anti-drain valve prevents oil from running into the crankcase after the engine has stopped. This will prevent an oil shortage the next time the engine is started.

In most cars today, non-separable filters are used, the design of which provides for the presence of the valves described above. But it is impossible to look inside to judge the quality of the workmanship. Many counterfeits for famous brands are produced without valves, which causes serious damage to engines.

Modern technologies

Air filters have come a long way in terms of technology. The fact is that cars today use turbocharged engines that require a lot of air. The filter should be compact and provide several times better ventilation. In addition, the durability of his work should not diminish. Therefore, in addition to paper, fibrous or synthetic filters appeared.

The secret of efficiency

Papers shield contaminants only on the surface, while fibrous particles trap and accumulate solid particles throughout the depth of the layer. Fiber filters are more resistant to external aggressive environments and last longer.

Interestingly, a synthetic filter can be several times more efficient than a paper filter of the same size. So under no circumstances should a paper filter, identical in size, designed for a naturally aspirated engine, be placed on a powerful turbo engine

Often salespeople in stores are cunning and offer a cheaper filter. Yes, it fits in size, but not in performance.

Fuel “self-cleaning”

Another interesting fact: the fuel in the car tank is gradually becoming cleaner. The fact is that a standard fuel pump has a capacity of about 60 l/h and creates a pre-pressure in the system. And the car consumes much less petrol or diesel. Therefore, the residues are returned to the tank through the return line each time they pass through the filter.

But unlike the oil filter, there are no bypass valves here. Therefore, a clogged filter will gradually “suffocate” and kill the fuel pump, making it more and more difficult to pump fuel.

Which one to choose?

Despite the fact that filters are consumables, their choice should be taken seriously. All power and lubrication systems on modern automobiles are meticulously designed and operate almost to the limit of their capabilities. Any deviation from the specified parameters can lead to expensive repairs.

But spending kilos of money on filters from well-known brands is also not an option. Today, many companies have left Russia and counterfeit products have flooded the market.

To solve the problem, we have released high-quality car filters under the Za Rulem brand. They are produced in Russia, therefore they are inexpensive, but they fully meet all the requirements of car manufacturers.
