Problems solved by technology

[0004] It can be seen that the shortcomings of the existing fuel filter are: the life state of the filter cannot be accurately grasped, the actual fuel pollution degree and the life cycle of the filter can be truly reflected, and the driver cannot be accurately prompted to replace it in time, so it is difficult to guarantee The oil supply system works reliably, greatly reducing the power and economy of the engine

Abstract

The invention relates to a modularized fuel oil alarm coarse filter, which comprises a filter holder (1) provided with an oil inlet (11) and an oil outlet (12), a rotary fuel oil coarse filter (2), an oil inlet pipe joint (3), an oil outlet pipe joint (4) and a negative pressure alarm (5), wherein the rotary fuel oil coarse filter is arranged on the filter holder provided with the oil inlet and oil outlet; and the negative pressure alarm is arranged at the oil outlet end of the filter holder provided with the oil inlet and the oil outlet. The coarse filter disclosed by the invention has the advantages of small occupied space on an engine, convenience for installation and replacement, compact structure, connection reliability and capability of embodying the actual fuel oil pollution degreereally so as to be replaced and maintained in time, thereby improving the reliability of an oil supply system and greatly reducing the maintenance cost of the engine.

Description

technical field [0001] The invention relates to an engine accessory, in particular to a modular fuel alarm coarse filter. Background technique [0002] At present, with the increasingly stringent engine emission regulations, the precision and cost of the oil supply system have also increased accordingly. Due to the relatively poor quality of domestic diesel oil and regional differences, the oil products in large cities are relatively small The oil quality in cities is better, and the oil quality in eastern cities is better than that in western cities. It is not practical to replace the filter according to the maintenance cycle on our filter: for example, 10000-12000 kilometers or 200-250 hours; when a car If the car is filled with fuel with poor oil quality for a long time, the life of the fuel filter may not reach the replacement mileage or replacement cycle marked on our product, so the filter has reached the resistance point at the end of its life, and it is still going o...
