Embodiment Construction

[0248] 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 energy saving and emission reduction, in particular to a two-stroke gasoline engine for arranging a pressure crankshaft for valve control over pre-burning scavenging gas in a scavenging channel. The two-stroke gasoline engine is characterized in that a valve device synchronous with the crankshaft is arranged, a C-shaped ring (56a) of a crankshaft valve (56) is arranged on the crankshaft (57), and pressure rings (56f) with oblique angles are arranged on the two side edges of a small segment of opening of the C-shaped ring of the crankshaft valve (56); when the side edges of logarithmic spirals, of the two side edges of the small segment of opening, of the pressure rings rotate along with the crankshaft, the effect that the logarithmic spirals with equal pressure corners affect the airflow and the buffering effect are achieved when an opening communicated with a crankshaft tank of the scavenging channel of an air cylinder is opened and closed; and a gap (56 delta) between the outer diameter of an outer circle of each pressure ring and the opening communicated with the crankshaft tank of the scavenging channel of the air cylinder of an engine 1E38F ranges from 0.02 millimeter to 0.08 millimeter, an thus the two-stroke gasoline engine for arranging the pressure crankshaft for valve control over the pre-burning scavenging gas in the scavenging channel is formed.

Description

[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 and convergent Beaufort blade wall and an additional scavenging channel The utility model relates to a two-stroke gasoline engine with pressure cra...
