Abstract
The left box body of divider wall containing multiple through-holes is with the usefulness of the two stroke engine of auxiliary scavenging: the left box body is equipped with the divider wall containing multiple through-holes, the difficulty of manufacture is just reduced greatly revolutionaryly, because being easy to die casting demoulding divider wall on the cabinet of plain structure, and die casting demoulding divider wall is difficult in the piston/cylinder of depths complexity；The top of divider wall is equipped with 3 sections of camber lines, and the camber line of the centre of 3 sections of camber lines is circular arc line (527), and the both sides of 3 sections of camber lines are logatithmic spiral section (525) and cube curved section (526)；Its cross section of piston is one section of cube curve；The gabarit of the valve sheet of carburetor is a cube curve；And the face of the valve sheet of the carburetor of engine is a cube curve；Multiple kinematic pairs of engine plate indium cadmium；Engine hydrogen fuel tanks and oxygen cylinder.
Description
The present invention relates in a kind of combustion apparatus combustion chamber and igniter, especially have letter in the improvement of internal combustion engine
Number waves combustion chamber and with have the internal combustion engine ignition device of active receiving electrode and fine motion discharge electrode collocation on the basis of, into one
It walks the two stroke engine of improved tool periodic function gibbs overshoot convergence wave Fourier piece wall and adds touching in scavenging channel
The left box body of matchmaker's strainer valve control pre-burning scavenging and the divider wall containing multiple through-holes is belonged to the two-stroke oxyhydrogen engine of auxiliary scavenging
In field of internal combustion engine.
Background technique
For the igniter in combustion apparatus, especially gasoline motor spark plug, it is widely used in high voltage pulse
Electric current is introduced into combustion chamber, makes the gaseous mixture sparking of inspiration cylinder and lights, and then diffusion combustion and breaks out work done.It is existing
Between the external connector of spark plug and the spark cap for having rubber jar, has sometimes and loosely dissipate scattered phenomenon.Existing spark plug
Inside, though being equipped with glass-sealing agent makees resistance, only impedance；If adding induction reactance and capacitive reactance, the suitable circuit RCL is formed, then
Have the effect for more preferably inhibiting radio interference.Multiple tracks umbrella rib on insulator can also be improved to sawtooth by semi-circular cross-section
Tee section climbs electric channel and preferably blocks rubber jar more to insulate.The heat dissipation of the metal shell of existing spark plug is also
It can further improve.The electrode of existing spark plug, as one can imagine, there is easy coking, an easy ablation, single-point arcing, low temperature difficult point
Disadvantage；If electrode innovation be it is movable, when there is improvement.It is but inperfect in every way moreover there are many original combustion chambers
's；In addition to crossing advantage, there is shortcoming；Such as wedge-section combustion chamber, at spark plug, operating condition seems gaseous mixture undue concentration
Roughly；For another example bathtub shaped combustion chamber, the shape of prolate, making squish, the effect is relatively poor, and flame travel is also longer,
Burn rate is relatively low, and burning time is long, and rate of explosion is low, and surface to volume ratio F/V is larger, is unfavorable to HC discharge.For another example
Bowl-in-piston chamber, hemispherical combustion chamber, fluffy shape combustion chamber and other types combustion chamber such as generate the auxiliary combustion chamber of turbulent flow, double
Spark plug combustion chamber, the combustion chamber of plane is each has something to recommend him；But the invention that the mankind aspire after perfection be it is endless, piston also has
Very big potentiality can be dug.The so-called best geometry of combustion chamber and piston is no doubt important, but want and engine model adaptation and with
Igniter collocation, just there is preferable effect.Especially two-stroke gasoline engine is more worse than the fuel economy of four-stroke gasoline engine,
Hydrocarbon emission Chang Chaobiao in tail gas.Combustion chambers of internal combustion engines and piston and collocation with igniter, are one and are related to
