Abstract
The utility model provides a kind of engine air-intake structure, including air inlet pipeline and the turbocharger and electric booster that are arranged in parallel on air inlet pipeline；By-passing valve is fixed with the pipeline of turbocharger and electric booster upstream；The by-passing valve is connected with car running computer；The car running computer controls by-passing valve to turbocharger or electric booster air inlet according to the rotating speed of present engine.Compared with prior art, can solve the problems, such as turbocharger operation sluggishness instantly, the pollutant such as soot, particulate matter, allows engine also to possess optimal performance when low speed when reducing engine start, reduces unnecessary oil consumption, increases fuel-economy type.
Description
Technical field
Diesel engine intake supercharging technology field is the utility model is related to, specifically a kind of engine air-intake structure.
Background technology
When diesel engine works, the problem of conventional exhaust is turbocharger supercharged sluggish at present, underload, run at a low speed when
In the presence of start it is powerless, and thus booster intervene when lofty sense the problems such as.So that diesel engine fuel consumption increases, burning is not
Fully, atmospheric environment while is also polluted.
Utility model content
When the purpose of this utility model is to solve diesel engine low speed in the prior art, conventional exhaust turbocharger increases
Press the defects of sluggish, there is provided a kind of engine air-intake structure solves the above problems.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of engine air-intake structure, including air inlet pipeline and the turbocharger that is arranged in parallel on air inlet pipeline
And electric booster；By-passing valve is fixed with the pipeline of turbocharger and electric booster upstream；The by-passing valve and row
Car computer connects；The car running computer controls by-passing valve to turbocharger or electronic supercharging according to the rotating speed of present engine
Device air inlet.
Preferably, the upstream end of the air inlet pipeline and the gas outlet of air filter connect, and are divided into two by the by-passing valve
Branch road；The turbocharger and electric booster are separately positioned on two branch roads；The turbocharger and electric booster
Downstream pipe accumulate a pipeline and access in cold water storage cistern.
Preferably, the by-passing valve is three-way magnetic valve.
The utility model compared with prior art, has the advantages that：
It the utility model is related to diesel pressure booster arrangement.Operating mode, selection according to residing for engine by by-passing valve
Which kind of booster work switched.Allow electric booster to work in low speed, worked by exhaust-driven turbo-charger exhaust-gas turbo charger during high speed, make to start
Machine remains optimum condition.The structure can solve the problems, such as turbocharger operation sluggishness instantly, reduce engine start
When the pollutant such as soot, particulate matter, allow engine also to possess optimal performance when low speed, reduce unnecessary oil
Consumption, supercharging fuel economy.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
The effect of to make to architectural feature of the present utility model and being reached, has a better understanding and awareness, to compared with
Good embodiment and accompanying drawing coordinate detailed description, are described as follows：
A kind of engine air-intake structure, including air inlet pipeline and the turbocharger that is arranged in parallel on air inlet pipeline
And electric booster；By-passing valve is fixed with the pipeline of turbocharger and electric booster upstream；By-passing valve and driving electricity
Brain connects；Car running computer controls by-passing valve to turbocharger or electric booster air inlet according to the rotating speed of present engine.
By-passing valve is generally three-way magnetic valve.
The upstream end of air inlet pipeline and the gas outlet of air filter connect, and are divided into two branch roads by by-passing valve；Turbocharger
It is separately positioned on electric booster on two branch roads；The downstream pipe of turbocharger and electric booster accumulates a pipeline
And cold water storage cistern in accessing, the air inlet pipe of engine is then accessed again.
During work, engine is controlled in low speed by by-passing valve, and the air-flow to come from air filter increases via electric booster
Pressure, the air-flow after supercharging enter back into air inlet pipe after water tank cools down.The power resources of electric booster are powered in storage battery, and
And electric booster has controllability, can need to be adjusted according to engine charge.When engine is in high speed, generally
Rotating speed reaches 2000 turns, and electric booster has been not enough to provide required air inflow, and car running computer (ECU) will control side
Port valve closes the inlet end of electric booster, and electric booster is closed.By-passing valve switching inlet air flow enters turbocharger simultaneously,
Now the exhaust energy of engine there is enough speed and energy to be enough to promote turbocharger to operate.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply principle of the present utility model, the utility model also has respectively on the premise of the spirit and scope of the utility model is not departed from
Kind changes and improvements, these changes and improvements are both fallen within claimed the scope of the utility model.The requires of the utility model
Protection domain defined by appended claims and its equivalent.
