Fuel filter
Afuel filteris afilterused to screen out foreign particles or liquids from the fuel. Mostinternal combustion enginesuse a fuel filter, in order to protect the components in the fuel system.
Filters for foreign particles[edit]
Unfiltered fuel may contain several kinds of contamination, for example paint chips and dirt that has entered the fuel tank while filling, or rust caused by moisture in a steel tank.[citation needed]If these substances are not removed before the fuel enters the system, they will cause rapid wear and failure of the fuel pump and injectors.[1]
The filters are normally made into cartridges containing afilter paper.[citation needed]Fuel filters need to be maintained or replaced at regular intervals.
Filters for foreign liquids[edit]
Somediesel enginesuse a bowl-like design to collect water in the bottom of the filter (as diesel floats on top of water).[citation needed]The water can then be drained off by opening a valve in the bottom of the bowl and letting it run out, until only the fuel remains.
