The role of the fuel filter is to remove the solid debris contained in the fuel to prevent fuel
system blockage (especially the nozzle) to reduce mechanical wear and
tear, to ensure stable operation of the engine. In addition, the fuel filter also has the role of filtering water, to avoid fatal damage to the engine water.
Fuel filters are divided
into two types: one is the external filter, usually located in the
lower part of the chassis; the other is built-in filter, located in the
fuel tank. Among them, the external filter, can be divided into straight
into the general and with the return line 2 categories.
Different vehicles,
fuel filter replacement cycle is different, it is recommended for every
50,000 to 700,000 km to replace a fuel filter. Fuel quality of the poor
areas, should be appropriately shortened filter replacement cycle.
From time to time to replace the fuel filter will be problems
Fuel filter is the role
of fuel impurities in the filter, after prolonged use, the fuel filter
may be blocked by impurities within the oil supply, resulting in fuel
supply to reduce the engine starting difficult. In addition, long-term
fuel filter blockage, will lead to premature damage to the fuel pump.
The consequences of using substandard low-quality fuel filters
Poor fuel filte:
low-quality material using, less than the expected filtration effect.
Long-term use of low-quality filter, filter element may lead to block
the oil, resulting in insufficient fuel pressure, the vehicle can not
start.
