Knowledge of gasoline engine oil a/filter function to discern between true and false
According to the periodicity of the car, 5000 kilometers know first, after the first confirmed will be little maintenance and maintenance on a regular basis, generally is two times a year, little maintenance, a major maintenance. The so-called little maintenance, regular maintenance in oil change and oil filter; While the big maintenance is oil change, oil filter, air filter and fuel filter, the oil change is what we say at ordinary times machine oil filter and a /. Regular maintenance is especially important for the using performance and life of the car, if regular maintenance will prolong the service life of the vehicle, to everyone explanation before oil filter, today to give you a detailed introduction to the fuel filter.
A, the classification of the fuel filter
In the following article, the main universal is fuel filter for everybody, including the classification, function and maintenance cycle and true and false discrimination.
Fuel filter categories:
Nowadays, the types of fuel filter are divided into the following three: back to oil GuanLuShi, integrated type, straight into straight out type oil pump assembly. And some type, straight into the straight back to oil GuanLuShi fuel filter are single oriented, so must pay attention to the direction when installation.
Back to the oil vapor GuanLuShi filter
Compared to the first, back to the oil GuanLuShi gasoline filter more than a return pipe, the role of the return pipe is mainly within the guide rail of the spray oil unused fuel transfer to the tank. And in terms of advantages and disadvantages, and straight into the straight type fuel filter and no too much difference.
Integrated oil pump assembly type steam filter
Compared with the former two, integrated oil pump assembly type fuel filter both in volume or changing the step has bigger difference. Integrated oil pump assembly type gasoline filter including the gasoline pump, relief valve, filter and float sensor. Its advantage lies in the large volume, high gas pass rate, not easy jam; And in the insufficient aspects mainly reflects on the cost and difficulty of replacement.
Integrated oil pump assembly type steam filter disassembling
In addition, in the aspect of disassembling note that integrated oil pump assembly type fuel filter disassembling more troublesome, first to remove the rear seat and cover plate after to see the mounting location.
Straight into the straight type steam filter
Direct into straight out of fuel filter is easy to understand, is simply one end is fuel filter inlet; On the other side is the oil outlet. Its advantage is small size, easy disassembling and lower cost; Not mainly reflects on the straight into straight out, because this kind of fuel filter is a single line of concatenated, causing oil plug so easily.
Second, the fuel filter function:
The importance of gasoline for cars is like food for the importance of the human body, gas supply, vehicles. In addition, in terms of fuel oil, if oil is not very good, gasoline contains impurities inside is more, it can within the engine nozzle, fuel pump, fuel line parts damage, thus affecting ?
Steam filter function
Therefore, at this time, the effect of fuel filter is fully reflected. In simple terms, the function of the fuel filter is to contain iron oxide, dust etc in the gas solid impurities or filtered water, on the one hand, can reduce the rate of plug nozzle was impurities; On the other hand can also ensure that flows into the fuel system of gasoline oil.
Three, fuel filter maintenance cycle:
Steam filter maintenance cycle
Just like the rest of the automotive filter, each brand dealers will also fuel filter in vulnerability to consumable parts. Dongfeng Peugeot, for example, the quality guarantee period for the fuel filter 1 month / 5000 km; But in terms of change, although each brand car accessories or have a different shape and quality, but the fuel filter is usually replaced in the vehicle driving to 30000 km. If use don't change for a long time, is likely to cause fuel filter part function is lost, thus affect the normal work of the engine.
Four, true and false fuel filter (filter shell, for example)
In general, the difference between true and false fuel filter lies mainly in the following aspects:
Appearance: work quality
False fuel filter is coarser, in detail with the naked eye can see; In addition, the weight is also different, because of the different selection of material, false light fuel filter.
False steam filter characteristics
Car in addition, you also know that using bolo false fuel filter on the one hand, the fuel system will damage, reduce the service life of the engine; Indirect damage such as nozzle parts on the other hand, affect the injection process, this causes engine power, fuel consumption increase, and increase emissions of harmful substances.
True steam filter characteristics
Filter paper: filtering capability
In terms of filter paper, fake petrol filter filtration material is often used by unqualified, it will do the impurity in the gas filter is not sufficient, long-term use will affect the normal work of the fuel system.
Life aspect: length of service life
Life, fake fuel filter in the filter material is bad, on the one hand, easy to premature damage; On the other hand it is produced by the filter paper debris easily into the gasoline, which could lead to oil blockage or damage to the gasoline pump.
