Description
Technical field
The utility model relates to a kind of filter cleaner and comprises the low pressure oil way of this filter cleaner.
Background technique
Because vehicle low pressure oil way is arranged with trend comparatively complicated, existing very long pipeline, has again the assemblies such as strainer, secondary filter, oil pump, causes the change of existing height in whole pipeline, have again the change of inner chamber thickness.After a small amount of air enters oil circuit, cylinder can't be arrived immediately, comparatively multiple fuel is also had to supply engine combustion a period of time above in oil circuit, therefore motor normally can start, work, in this process, air runs forward in pipeline, and on tubule road, place is disperseed, and assembles at larger inner chamber, position higher position, once more air accumulation reaches cylinder, engine misses must be caused.Air in vehicle low pressure oil way produces and mainly contains following four aspects: 1, vehicle maintenance more renew cartridge time, do not fill it up with oil in new filter core on request and just install on motor, and do not open the exhaust of bleeder screw thorough pump oil after more renew cartridge; 2, vehicle oil way is arranged unreasonable, and oil pipe connects filter cleaner from top to bottom, and the oil more during renew cartridge in oil pipe flows out, oil pipe is drained, and air enters; 3, low pressure oil way itself is poorly sealed, causes air to enter low pressure oil way; 4, vehicle travel process moderately gusty air, in fuel tank, fuel oil stirs, and air is mixed in oil, enters oil circuit.
The automatic vent of prior art mesolow oil circuit is mainly realized by the motor-drive pump that oil and water seperator is integrated, after vehicle powers on, whole low pressure oil way is got through by motor-drive pump work, air in low pressure oil way is also discharged, but the air having following several situation to gather cannot be discharged: 1, be limited by the relation that thick essence considers stand structure, the air accumulated on fuel filter seat threaded pipe cannot be discharged.In the running of 2, vehicle, exist poorly sealed due to oil circuit own and be inhaled into the air of low pressure oil way; 3, vehicle travel process moderately gusty air, in fuel tank, fuel oil stirs, and air is mixed in oil, enters the air of low pressure oil way.As shown in Figure 1, do not have gas storage space in prior art in filter cleaner, the air in engine operation process can enter motor with fuel oil.In sum, existing automatic vent technology can only have certain emptying to the air existed in low pressure oil way before engine start, and in engine operation process because a variety of causes is mixed into air in low pressure oil way without effect, along with air accumulation to a certain extent, after entering cylinder, engine misses will inevitably be caused.
