Description

Self-regulated pressurized machine

Technical field

The utility model relates to auto parts and components, particularly a kind of energy saving device that can improve engine power minimizing exhaust emissions.

Background technique

Because automobile running condition constantly changes, required engine power also should be done corresponding variation, the quantity that changes engine power and be the combustible gas feeding by change in vehicle traveling process realizes, for this reason, Carburetor is provided with closure, closure is a circle or oval flaky valve normally, can turn several angle around its minor axis, and closure is connected with a series of rod members with the accelerator card in operator cabin.Driver will speed up the plate extreme lower position of stepping on, and closure is all opened, and now the channel cross-sectional area of mixed gas is maximum, and when driver loosens accelerator card completely, pipeline section that closure passes through mixed gas is long-pending reduces to minimum.When engine speed is constant, throttle opening is larger, and in whole admission line, resistance is less, and the air mass flow in air duct and flow velocity are larger, thereby have strengthened engine power.

Modern advanced automotive engineering is thought, improve eddy current and the turbulent extent of mixed gas in cylinder, contribute to strengthen air-fuel mixture, guarantee oil gas fast and perfect combustion, this is because the velocity of propagation of flame in static or laminar flow mixed gas is generally no more than 1m/s, and velocity of propagation of flame when eddy current and turbulent flow can be up to 100m/s.Also think and can by Lean Burning Technique, reduce the discharge amount of CO, make idling oil consumption decline 40%.Lean combustion refers to that gasoline air fuel ratio is greater than 18: 1 or rarer mixed gas, can not make the fuel can not perfect combustion and produce CO, also favourable NO, NO ₂the reduction of discharge amount.Obviously, lean combustion great advantage is to reduce CO, NO, NO simultaneously ₂discharge amount.Lean combustion relies on the motor of stratified mixture combustion (stratified charge) to realize at present, well-known, used rare, the problem of the mixed gas in petrol engine catches fire scope is to be to be difficult to form fiery core.Even if adopt high-energy ignition system to light a fire, because the fuel quantity in micro volume very little, so be often not enough to the normal propagation of flame support.Stratified mixture combustion is exactly reasonably to organize the mixed gas in cylinder to distribute, make spark plug around have denseer mixed gas, and most of region in firing chamber have very rare mixed gas, can guarantee like this normal ignition and burning, also expanded lean-burn limit of misfire simultaneously, can fuel-economizing and minimizing discharge.And stratified mixture combustion (stratified charge) requires to form in intake process around the organized air swirl perpendicular to cylinder axis direction rotation or claims eddy flow, be also called and roll stream.Roll stream and be crushed gradually in compression process, near top dead center, be broken into many undersized eddy current and turbulent flow, can greatly improve combustion process.Obviously between closure and inlet manifold, just form eddy current, the fuel oil that makes the ejection of oil sprayer in the intake valve front end in inlet manifold in eddy current, is beneficial to the formation of stratified mixture combustion immediately.

But current throttle valve structure not only can not form eddy current, but also form and reflux in closure rear end, be unfavorable for the formation of stratified mixture combustion.

On the other hand, according to a large amount of experimental results show that, carbon distribution after closure is not exclusively to be caused by the entrained carbon distribution of machine oil waste gas, after valve overlap, because exhaust pressure increases, suction pressure is now relatively little, when waste gas enters exhaust piping, also some enters exhaust duct, although can directly not discharge from exhaust duct, but moment stops after can concentrating at closure, then with air inlet, reenter again cylinder, this ignorance is exactly to cause the main cause that engine air throttle pollutes and engine interior pollutes, the air sucking is not exclusively pure air, but by approximately 1/3 waste gas.Melting concn declines, and when mixed gas burns again, has reduced its combustion value, and design power cannot be brought into play completely.The of a specified duration formation that causes carbon distribution, imperfect combustion, makes power cannot reach design load, thereby has reduced power, has consumed the energy more, and partial combustion also makes tail gas index obviously improve, and causes motor to pollute and atmospheric pollution.

Model utility content

The technical problem that the utility model solves is to overcome the defect that in prior art, closure exists, by self-regulated pressurized machine is set after closure, utilize the fan-shaped valve blade in self-regulated pressurized machine, the air-flow running parallel in pipeline is carried out to share split, by several angle spiral, enter inlet manifold, form eddy current, and push and dwindle air-flow, thereby strengthen, enter engine air capacity, improve cylinder air stream ratio, improve engine power output, reduce the discharge of harmful gas.

In order to achieve the above object, the utility model has been taked following technological scheme 2

A kind of self-regulated pressurized machine, comprise air inlet valve body, central guiding fluidization tower, the gentle gate flap sheet of Leaf Conductance fluidization tower fixing rod, described central guiding fluidization tower top arranges fair water cone, described central guiding fluidization tower upper end arranges Leaf Conductance fluidization tower fixing rod, the described Leaf Conductance fluidization tower fixing rod the other end is fixedly connected with air inlet valve body, on described each Leaf Conductance fluidization tower fixing rod, a valve blade is set, it is 45 °-70 ° that described valve blade shroud moves angle around Leaf Conductance fluidization tower fixing rod, described central guiding fluidization tower arranges housing outward, described central guiding fluidization tower is through housing bottom, described air inlet valve body bottom arranges screw rod, described air inlet valve body is connected by screw rod with housing,

Described Leaf Conductance fluidization tower fixing rod is 3-10;

Described valve blade is fan-shaped;

On described central guiding fluidization tower, pressure spring is set;

Between described pressure spring and valve blade, spring top flat is set.

Working principle: after self-regulated pressurized machine is fixed on to closure with flange plate, connect admission line, fan-shaped valve blade is adjusting angle automatically, and therefore, valve blade can need to be opened different angles according to the difference of air inlet, makes air fuel ratio reach rational ratio.Every valve blade be take the contact that this blade top is one end; Every valve blade shroud is opened to one end inclination control around its Leaf Conductance fluidization tower fixing rod simultaneously, and the gap of gas between the valve blade of every inclination obliquely enters pipeline, forms eddy current.

Beneficial effect:

The utility model is simple in structure, uses safety, reliable, and repacking is convenient, the air-flow running parallel in pipeline is carried out to share split, and enter intake duct by several angle spiral, form eddy current, and extruding dwindles air-flow, thereby strengthen, enter engine air capacity, improve cylinder air stream ratio, increase suction pressure, overcome air inlet return-air problem, Lean Burning Technique is achieved, can reduces CO, NO, NO ₂discharge amount, make idling oil consumption decline 40%, motor is operated steadily, and can keep high torque during the slow-speed of revolution, reduce automobile low cruise cost.
