Embodiment Construction

[0247] Refer to the Fourier function's rectangular wave in the mathematical physics method of advanced mathematics, the overshoot of the Gibbs phenomenon, the overshoot convergence wave and the reference delay theorem, displacement theorem, and convolution theorem to approximate a single Fourier function The expansion of the circular frequency is similar to the gradually attenuating spectrum described by the Fourier series, with multiple peak waves that change from large to small and from sparse to dense. What mathematical physics describes should be a high-level generalization of many actual phenomena. Engine scavenging The law of turbulent flow motion should not be an exception and completely surpassed, and there should be some similarities or internal correlations or complement each other more or less; on the forming die core of the die-casting mold, the imitation is close to and seems to be internally related. The Fourier function gap (53j) and the jump inflection point (54...

Abstract

The invention relates to a two-stroke gasoline engine for controlling pre-burning scavenging by adding a clearance crankshaft valve in a scavenging channel, which has the advantages of energy conservation and emission reduction. The two-stroke gasoline engine is provided with an air valve device synchronized with a crankshaft, and a C-shaped ring (56a) of the crankshaft valve (56) is arranged on the crankshaft (57). The two side edges with a small segment of opening of the C-shaped ring of the crankshaft valve (56) is designed into oblique wedge rings (56b) with oblique angles. When the side edges with the oblique angles of the two side edges with the small segment of opening of the C-shaped ring rotate along with the crankshaft and the opening part, communicated with a crankcase, of the scavenging channel of a cylinder is closed, the effects of cutting airflow and reducing mutation impact are formed. The gap (56deltal) between the outer diameter of the outer circle of the C-shaped ring and the opening part, communicated with a crankcase, of the scavenging channel of the cylinder of the engine 1E34F is 0.01-0.06mm, and therefore the two-stroke gasoline engine for controlling pre-burning scavenging by adding the clearance crankshaft valve in the scavenging channel is formed.

Description

technical field [0001] The invention relates to a combustion chamber and an ignition device in combustion equipment, especially on the basis of an improved combustion chamber with a function wave of an internal combustion engine and an ignition device for an internal combustion engine with a movable receiving electrode and a micro-moving discharge electrode. And on the basis of a gasoline engine with double auxiliary skirts on the piston skirt to reduce hydrocarbon emissions, and on the basis of a gasoline engine with improved piston skirt logarithmic differential equiangular skirt turbulence back channeling and emission reduction, and On the basis of the improved two-stroke gasoline engine with narrowed left and right box seats and double auxiliary vents to reduce emissions, a further improved two-stroke engine with periodic function Gibbs overshoot converges on the Beaufort blade wall and adds air in the scavenging channel. The invention relates to a two-stroke gasoline engi...
