Abstract
Be applied in the novel fuel evaporating system on small displacement supercharged engine, the technical field that the fuel evaporation that the utility model relates to supercharged engine reclaims.It is malleation to overcome intake manifold in existing supercharged engine major part working environment, traditional fuel vapor sucked the infeasible problem of intake manifold by negative pressure.The admission port of the steam output end mouth of its canister control valve and the admission port of the first one-way valve and the second one-way valve is interconnected, the air outlet of the steam output end mouth of the second one-way valve and the front end airflow pipe of pressurized machine and air filter is interconnected, and the steam output end mouth of the first one-way valve and the air outlet of throttle body and the intake manifold of motor are interconnected.Under the utility model had both met natural aspiration state, fuel vapor in fuel tank directly enters engine intake manifold, and after ensureing pressurized machine work again, fuel vapor participates in burning and ensureing that air cannot blow back in canister by pressurized machine front end pipeline air inlet engine.
Description
Technical field
The technical field that the fuel evaporation that the utility model relates to supercharged engine reclaims.
Background technique
Gasoline is volatile fuel, fuel oil in fuel tank can volatilize very soon increases the pressure of fuel tank internal, certain danger will be produced when pressure arrives certain value, angle for fuel saving and protection of the environment is set out, petrol engine increases EVAP Evaporative System, namely the canister arranged, the inner active carbon very strong by adsorptivity of canister is filled, fuel vapor unnecessary in fuel tank is no longer discharged in air, when start time, canister control valve is opened in good time, again the fuel vapor of absorption is poured into intake manifold by negative pressure, to reach the object of saving fuel oil and environmental protection.But intake manifold is malleation in supercharged engine major part working environment, traditional fuel vapor to be sucked intake manifold by negative pressure infeasible.
Summary of the invention
The purpose of this utility model is to provide a kind of novel fuel evaporating system be applied on small displacement supercharged engine, the utility model is malleation to overcome intake manifold in existing supercharged engine major part working environment, traditional fuel vapor sucked the infeasible problem of intake manifold by negative pressure.
A kind of novel fuel evaporating system be applied on small displacement supercharged engine of the present utility model, it is made up of fuel tank, canister control valve, the first one-way valve, the second one-way valve, throttle body, intercooler, pressurized machine, air filter, canister;
The fuel-steam outlet of fuel tank is communicated with the admission port of canister control valve, the steam output end mouth of canister control valve is communicated with the steam inlet of canister control valve, the admission port of the steam output end mouth of canister control valve and the admission port of the first one-way valve and the second one-way valve is interconnected, the air outlet of the steam output end mouth of the second one-way valve and the front end airflow pipe of pressurized machine and air filter is interconnected, the air outlet of pressurized machine is communicated with the air inlet port of throttle body by intercooler, the steam output end mouth of the first one-way valve and the air outlet of throttle body and the intake manifold of motor are interconnected.
Under the utility model had both met natural aspiration state, fuel vapor in fuel tank directly enters engine intake manifold, when can ensure that again motor is malleation in intake manifold after pressurized machine work, fuel vapor participates in burning and ensureing that air cannot blow back in canister by pressurized machine front end pipeline air inlet engine, reaches the object of fuel-economizing and environmental protection.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
Embodiment one: composition graphs 1 illustrates present embodiment, present embodiment is made up of fuel tank 1, canister control valve 2, first one-way valve 3, second one-way valve 3-1, throttle body 4, intercooler 5, pressurized machine 6, air filter 7, canister 8;
The fuel-steam outlet of fuel tank 1 is communicated with the admission port of canister control valve 2, the steam output end mouth of canister control valve 2 is communicated with the steam inlet of canister control valve 2, the admission port of the steam output end mouth of canister control valve 2 and the admission port of the first one-way valve 3 and the second one-way valve 3-1 is interconnected, the air outlet of the steam output end mouth of the second one-way valve 3-1 and the front end airflow pipe of pressurized machine 6 and air filter 7 is interconnected, the air outlet of pressurized machine 6 is communicated with the air inlet port of throttle body 4 by intercooler 5, the intake manifold of the steam output end mouth of the first one-way valve 3 and the air outlet of throttle body 4 and motor 9 is interconnected.
Working principle: the control strategy demarcated according to car load after fuel tank 1 intermediate fuel oil steam is adsorbed by canister 8 makes the unlatching of canister control valve 2, through the first one-way valve 3, second one-way valve 3-1, fuel vapor is led respectively in the intake manifold of motor 9 and the front end airflow pipe of the rear pressurized machine 6 of air filter 7.When motor 9 rotating speed is lower, when supercharging not yet got involved by pressurized machine 6, fuel vapor enters in the front end airflow pipe of intake manifold and pressurized machine 6 by the first one-way valve 3, when motor 9 rotating speed reaches 1700rpm, gas pressure in the intake manifold of now motor 9 is higher than the pressure of canister 8 intermediate fuel oil steam, first one-way valve 3 stops air blow back to enter in canister 8, and the fuel vapor simultaneously in canister 8 is entered in the front end airflow pipe of pressurized machine 6 by the second one-way valve 3-1.
