Description
Technical field
The utility model relates to a kind of filter devices, are specifically related to a kind of filter for fuel system.
Background technique
Canister is generally seated in front of petrol tank and engine.Since gasoline is a kind of volatile liquid, fire at normal temperature
Fuel tank is often fill with steam, and the effect of fuel vaporization and discharge control system is to introduce steam to burn and prevent from evaporateing into atmosphere
In.What this process played an important role is charcoal canister storage system.After engine misses, gasoline vapour and fresh air are in tank
Interior mixing is simultaneously stored in activated carbon canister, fuel evaporation after engine start, between activated carbon canister and inlet manifold
The electromagnetic valve of purification device is opened, and the gasoline vapour in activated carbon canister is inhaled into inlet manifold and participates in burning.Utilize activated carbon
It is communicated with atmosphere, pressure in trim tank prevents gas lock from causing to stop working.Fuel system air inlet, exhaust work principle are as follows:
Air inlet principle: vehicle driving engine operation, oil pump is pumped by fuel tank enters engine by pipeline road, oil
Case generates negative pressure, to can guarantee that oil pump works normally, avoids generation fuel tank from inhaling flat, and fuel tank must discharge air and enter fuel tank guarantee oil
Pump the pressure balance (allow there are pressure differences) worked normally, must design inlet channel, which includes pipeline, canister, air filter, work
Make route: atmosphere-air cleaner-pipeline-canister-pipeline-fuel tank；
Venting principleand: when gas station is refueled, fuel oil is added to oil vehicle by fuel charger (refueling nozzle) for fuel oil
In case, fuel tank is with the raising of oil level, and fuel tank generates positive pressure, to guarantee that fuel oil can normally add to nominal volume, to avoid generating
The counter of fuel oil is gushed after oil gun stops working in advance or oil gun stops working, and fuel tank must discharge oil gas and go out what fuel tank guarantee was normally refueled
Pressure balance (allow there are pressure differences), must design exhaust passage, which must design two-way, and channel is early period of refueling all the way
When (before 70% or so oil mass), operating path: fuel tank-gas exhaust piping-atmosphere, another paths are oiling whole process, work
Make route: fuel tank-pipeline canister-pipeline-air cleaner-atmosphere.
Function principle of the air cleaner in fuel system: when fuel tank air inlet, atmosphere is carried out dust, moisture content by air filter
It is effective to intercept and filter, clean, dry air is entered into fuel tank by canister, improves canister (to fuel oil when fuel tank is vented
Hydrocarbon absorption) Acceptable life.
There is significant limitations for existing air cleaner, and installation is cumbersome, so in order to solve above-mentioned ask
Topic designs a kind of filter for fuel system and is just particularly important.
