Gasoline filter, a kind of fuel filter, the main function is to filter impurities such as iron oxide, dust and water contained in gasoline. The filter can ensure the oil flowing into the engine system and reduce the probability of the fuel nozzle being blocked by impurities.
1. Maintenance cycle of gasoline filter
After the vehicle is driven for a certain distance, in order to work better, it needs to do small or large protection regularly.
Minor maintenance: oil, oil filter replacement;
Major maintenance: oil, oil filter, air filter and gasoline filter replacement.
2. Classification of gasoline filters
Gasoline filters are mainly divided into: straight in and straight out type, back to the oil pipeline type, integrated oil pump assembly type gasoline filters. In addition, straight in and straight out type, back to the oil pipe type gasoline filter, are single guide filter, installation should be careful not to install the reverse.
Straight-in straight-out filter:
Straight in and straight out type gasoline filter, one end of the filter is an oil inlet, the other end is an oil outlet. The gasoline filter is small in size, easy to disassemble and assemble, and the cost is relatively low. However, this kind of gasoline filter is a single pipeline series connection, easy to block the oil circuit.
Bring back oil line filter:
Back to the oil pipeline type gasoline filter, compared with the straight in and straight out type filter, more than a return oil pipe, the return oil pipe can be injected into the guide rail, the unused fuel to the tank.
Integrated oil pump assembly filter:
Integrated oil pump assembly type gasoline filter, compared with the direct in direct out type, back to the oil pipeline type gasoline filter, the cost and filter replacement difficulty is relatively high. The filter is composed of a gasoline pump, a pressure relief valve, a filter and a sub-sensor. This type of filter has large volume, high gasoline passing rate, and is not easy to clog.
In addition, when this type of filter is disassembled, the rear seat and cover plate must be removed to see the disassembly position of the filter.
