Abstract

The invention relates to the filed of energy conservation and emission reduction and provides a two-stroke gasoline engine with two auxiliary air ports for narrowing a left box seat and a right box seat and capable of reducing emission. The two-stroke gasoline engine has excellent emission reduction and standardization effects and can reach the standard of 50 grams and the standard of 39.9 grams, allowance is large, safety coefficients are large, wasted and defective products are small, and therefore the two-stroke gasoline engine has great significance for emission reduction and standardization of mass two-stroke gasoline engines. Several improvements are used in a comprehensive mode, and effects are good. The two-stroke gasoline engine is beneficial for producing turbulence so as to block waste gas flow backward, and therefore emission can be reduced. The two-stroke gasoline engine is characterized in that the two auxiliary air ports for narrowing the left box seat and the right box seat are matched with wedge turbulence back shifting pieces (46) and two auxiliary skirt edges (37) in use, wherein the wedge turbulence back shifting pieces (46) are symmetrically arranged on the left and the right of scavenging path openings (45) symmetrically arranged on the left and the right of a cylinder body (44), and the two auxiliary skirt edges (37) are additionally arranged on skirt portions of pistons. Thus, the emission can be reduced greatly.

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 plus double auxiliary skirt to reduce hydrocarbon emissions, and on the basis of improved piston skirt logarithmic differential equiangular skirt turbulent back channeling and emission reduction gasoline engine, further The invention relates to an improved two-stroke gasoline engine which reduces emissions by narrowing left and right box seats with double auxiliary vents, and belongs to the technical field of combustion chambers and turbulent scavenging of internal combustion engines. Background technique [0002] Ignition devices used in combustion equipment, esp...
