Abstract
The utility model belongs to a device capable of improving engine power and reducing exhaust gas emission. A throttle valve plate adopted is formed by at least 3 to 10 valve blades which are on the same plane and can open or close the cross section of a pipe controlled by the throttle valve at the same time; each valve blade encloses own valve rod and inclines to one end to control the opening; gas obliquely enters into the pipe from a clearance obliquely formed between the valve blades to form an eddy current; and the throttle valve body is provided with a multi-blade linkage structure for opening or sealing the valve blades at the same time. The device is favorable to formation of the eddy current in an intake manifold to directly pressurize the intake manifold, and is also favorable for stratified combustion and further lean combustion, as a result, the fuel can be combusted completely, the emission of CO, HC and NOx can be reduced, and the fuel is saved to lower the low-speed running cost of vehicles.
Description
Technical field
The utility model relates to a kind of 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, changing engine power in vehicle traveling process is to realize by the quantity that changes the combustible gas that feeds, for this reason, Carburetor is provided with closure, closure is circle or oval flaky valve normally, can turn several angle around its minor axis, and the interior accelerator card of closure and operator cabin is connected with a series of rod members.The driver will speed up the plate extreme lower position of stepping on, and closure is all opened, and this moment, the channel cross-sectional area of mixed gas was maximum.When the driver loosens accelerator card fully, the long-pending minimum that reduces to of pipeline section that closure passes through mixed gas.When engine speed was constant, throttle opening was larger, and then resistance is less in the whole admission line, and the air mass flow in the air duct and flow velocity are larger, thereby have strengthened engine power.
Modern advanced automotive engineering is thought, improves eddy current and the turbulent extent of mixed gas in the cylinder, helps to strengthen air-fuel mixture, guarantees fast and perfect combustion.This is because the velocity of propagation of flame in the static or laminar flow mixed gas generally is no more than 1m/s, and the velocity of propagation of flame when eddy current and turbulent flow can be up to 100m/s.Also think and the discharge amount that can reduce by Lean Burning Technique CO and HC make the idling oil consumption descend 40%.Lean combustion refers to the gasoline air fuel ratio greater than 18: 1 or rarer mixed gas, can not make the fuel can not perfect combustion and produce CO and HC, also favourable NO
xThe reduction of discharge amount.Obviously, the lean combustion great advantage is to reduce simultaneously CO, HC and NO
xDischarge amount.Lean combustion relies on the motor of stratified mixture combustion (stratified charge) to realize at present.As everyone knows, used rare, to be in the catch fire problem of the mixed gas in the scope of petrol engine be to be to be difficult to form fire nuclear for oneself.Even adopt high-energy ignition system to light a fire, because the fuel quantity in micro volume very little, so often be not enough to the normal propagation of flame support.Stratified mixture combustion is exactly reasonably to organize the mixed gas in the cylinder to distribute, around making spark plug denseer mixed gas is arranged, and the most of zone in the firing chamber has very rare mixed gas, can guarantee like this normal ignition and burning, simultaneously also expanded the lean-burn limit of misfire, but fuel-economizing and minimizing discharging.And stratified mixture combustion (stratified charge) requires to form organized air swirl or the title eddy flow that winds perpendicular to the cylinder axis direction rotation in intake process, also is called and rolls stream.Roll stream and in compression process, be crushed gradually, 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 of the oil sprayer ejection in the intake valve front end in inlet manifold is in the eddy current immediately, be beneficial to the formation of stratified mixture combustion.
But present throttle valve structure not only can not form eddy current, but also forms backflow in the closure rear end, is unfavorable for the formation of stratified mixture combustion.
On the other hand, according to a large amount of experimental results show that, carbon distribution behind the closure not exclusively is to be caused by the entrained carbon distribution of machine oil waste gas, after valve overlap, because exhaust pressure increases, the suction pressure less of this moment, when waste gas enters exhaust piping, also some enters exhaust duct, although can directly not discharge from exhaust duct, moment can concentrate at closure and stop afterwards, then reenter again cylinder with air inlet, this ignorance is exactly to cause engine air throttle to pollute and the main cause of engine interior pollution, and the air of suction not exclusively is pure air, but by about 1/3 waste gas.Melting concn descends, and when mixed gas burns again, has reduced its combustion value, so that design power can't be brought into play fully.The formation that causes carbon distribution of a specified duration, imperfect combustion so that power can't reach design load, thereby has reduced power, has consumed the energy more, and partial combustion also so that the tail gas index obviously improves, causes motor to pollute and atmospheric pollution.
