Should the hydraulic ejector valve of Chery 473 engine be adjusted?

Do not adjust the hydraulic jacking valve of Chery 473 engine. The limited filtration of the air filter actually means that it is in direct contact with the air. In fact, there is an air filter in front, which filters in front, but not everything can be filtered out, and dust or other dirty things will touch the throttle surface through the throttle.

Function of hydraulic air filter

The hydraulic air filter consists of an air filter and a refueling filter, which can not only prevent particulate pollutants from invading the system through the breathing port of the fuel tank, but also prevent particulate pollutants from mixing during refueling. Compared with non-metallic filter materials, copper-based powder metallurgy sintered filter has the characteristics of stable filtering accuracy, high strength, strong plasticity, convenient disassembly and cleaning, and can withstand thermal stress and impact and work normally at high temperature.

When the hydraulic system is working, the oil level in the oil tank will rise or fall from time to time. When it rises, it exhausts air from the inside out, and when it falls, it sucks air from the outside in. In order to purify the oil in the oil tank, an air filter is vertically installed on the tank cover plate to filter the inhaled air; At the same time, the air filter is also an oil inlet, and the injected new working oil must be filtered before entering the oil tank, thus filtering out the dirty particles in the oil.
