Embodiment Construction

[0132] As embodiment 2 of improvement 2, because the present invention particularly improves the electrode to be an electrode 12 with multiple sides and multiple folded gaps, it not only has the aforementioned three parts consisting of the protruding portion 16a, the curved portion 16b, and the curved portion 16c, The distance between the discharge electrode and the discharge electrode is equal to form the discharge gap between the receiving electrode and the discharge electrode, and it is longer than the original front line, and a plurality of sharp notches 17 are specially provided. Therefore, in the first stage of the spark ignition process, that is, the breakdown stage , which is conducive to discharge, so that the ion flow that has broken down the mixed gas runs from the receiving electrode to the discharging electrode. Although the peak current is large, the time of the entire breakdown stage is very short, only ten microseconds, so multiple sharp notches 17 are feasible....

Abstract

The invention relates to energy conservation and emission reduction, in particular to an emission-reduction two-stroke gasoline engine with scavenging passage wedge turbulent flow return sheets. The emission-reduction two-stroke gasoline engine is characterized in that in order to pursue scientific exploration, many improvements are performed on a spark plug such as internal inductive reactance is added on various fixed electrodes, an external dividing coupling is improved, a casing radiating fin is added, and especially a moving electrode and a micro electrode are arranged. In addition, combustion chambers are matched with various ignition devices, wherein the combustion chambers include combustion chamber with function waves and parabolic combustion chambers to be convexly and concavely matched and with function waves. A double-auxiliary skirt border is additionally arranged on a piston skirt portion. The wedge turbulent flow return sheets (46) are respectively symmetrically arranged on the left side and the right side of a scavenging passage of a cylinder, and each wedge turbulent flow return sheet comprises a scavenging passage (47), a wedge (48) connected with the scavenging passage, a return rid (49) connected with the scavenging passage and a turbulent flow shield (50) connected with the scavenging passage, and accordingly the emission-reduction two-stroke gasoline engine is favorable for generating turbulent flow at the scavenging passage position to resist waste gas returning and further to reduce emission, and finally the effect of reaching the emission reduction standard is achieved. The emission-reduction two-stroke gasoline engine has the advantages of being favorable for assisting guide, assisting emission reduction and noise reduction and assisting lubrication and heat dissipation, being reliable in igniting and improving efficiency.

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 the gasoline engine with piston skirt and double auxiliary skirt to reduce hydrocarbon emissions, a further improved two-stroke gasoline engine with scavenging port oblique wedge turbulent flow back channeling plate to reduce emissions belongs to the combustion chamber and The technical field of turbulent scavenging. Background technique [0002] Ignition devices used in combustion equipment, especially gasoline engine spark plugs, are widely used to introduce pulsed high-voltage current into the combustion chamber, so that the mixed gas sucked into the cylinder can be sparked and ignited, and then d...
