Under normal circumstances, we all know the vehicle after running for some mileage to do small maintenance or major maintenance. Well, this big, small maintenance are included what? Often say little maintenance, in fact, is to replace the vehicle oil and oil filter; and major maintenance is the replacement of the car's engine oil, oil filter, air filter and fuel filter, which is the so-called replacement oil filter and oil filter.
Fuel Filter Category:
Nowadays, the type of fuel filter is divided into the following three types: straight straight-through, back to the oil pipeline type, integrated oil pump assembly type. In addition, straight straight-through, back oil pipeline gasoline filters are single-oriented, so installation should pay attention to the direction.
Straight straight-through:
Straight straight-through fuel filter is well understood, simply put, is the fuel filter is the inlet end; the other end is the oil port. The advantage is small size, easy accessibility, low cost; and inadequate mainly in straight straight out on, since these fuel filter is a single line in series, and therefore likely to cause oil plug.
Back to the oil pipeline formula:
Compared to the first one, back to the oil pipeline gasoline filters more than a return line, the return line of the main action is to not run out within the injector rail fuel delivery to the fuel tank. In terms of advantages and disadvantages, and straight into the straight-through fuel filter is not much difference.
Integrated pump assembly type:
Compared to the first two, integrated oil pump assembly gasoline filters either in volume or in the replacement procedure has a relatively large difference. Integrated gasoline pump assembly includes a fuel pump filter, pressure relief valves, filters and automotive fuel tank float. The advantage is that bulky, gasoline through rate, clogging; in shortfalls mainly reflected in the costs and the replacement of the difficulty.
In addition, the disassembly should pay attention to that type of fuel filter integrated oil pump assembly disassembly is too much trouble, you must first remove the rear seat and removable cover before you see the location.
Fuel Filter effect:
The importance of gasoline for cars like the importance of food for the body, there is no supply of gasoline, vehicles unable to move. In addition, in terms of petrol oil, if oil is not very good, the impurities contained more gasoline, fuel injectors, fuel pumps, fuel lines and other components which would cause damage to the engine, thus affecting the fuel system normal work.
Therefore, at this time, the role of the fuel filter is completely manifested. Simply put, the role of the iron oxide fuel filter is contained in gasoline, dust or water to filter out solid impurities, one can reduce the chance of the injector blocked impurities; on the other hand can also guarantee gasoline flowing into the fuel oil system.
Gasoline filter maintenance cycle:
And the rest of the car, like the filter, the brand dealers will also be included in the fuel filter to wearing parts within easy consumption. Dongfeng Peugeot, for example, fuel filter warranty period is a month / 5000 km; and replacement, although the brand models accessories and quality or have a different shape, but the fuel filter is usually traveling in each vehicle Replace to 30,000 km when. If you do not replace long-term use, it is possible to cause partial loss of function of the fuel filter, thus affecting the normal operation of the engine.
