Abstract
The utility model discloses a single-cylinder double-sparkplug two-stroke petrol engine, which comprises a cylinder body, a piston, two sparkplugs and an ignition system. The piston is arranged inside the cylinder body. A main sparkplug and an auxiliary sparkplug are arranged at the upper portion of a cylinder body combustion chamber and respectively connected with the ignition system which is composed of a magnetor flywheel, a stator igniter and two relatively independent high voltage output systems. Two sparkplugs at the upper portion of a cylinder body combustion chamber are ignited simultaneously, thereby shortening spreading distance of combusted flare, enabling fuel to be fully combusted, having even explosion pressure, improving output power of the whole machine and reducing emission of harmful pollutants.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of single cylinder dual ignition plug two-stroke gasoline engine.
Background technique
Two stroke engine because have that compact structure, volume are little, light weight, running speed-raising are fast etc., and many remarkable advantages are widely used in many product scopes such as agricultural, forestry, gardening, family.But a spark plug is only assembled in existing cylinder of petrol engine firing chamber, so exist igniting back flame travel far away, pressure of explosion is inhomogeneous, and fuel combustion is insufficient, and output power is low, the shortcoming of discharging difference.
Therefore, concerning most of enterprises, it is lower to be badly in need of a kind of oil consumption, more powerful, the petrol engine that discharging complies with the national standard requirements.
The model utility content
The purpose of the utility model provides a kind of single cylinder dual ignition plug two-stroke gasoline engine; This petrol engine is lighted a fire owing to being provided with two spark plugs on top, cylinder body firing chamber simultaneously; Shortened the flame combustion propagation length greatly, made fuel combustion more abundant, pressure of explosion is more even; Improve the complete machine output power, reduced the discharging of noxious pollutant.
The technological scheme that the utility model is taked is:
A kind of single cylinder dual ignition plug two-stroke gasoline engine comprises cylinder body, piston, and spark plug and ignition system are formed, and it is characterized in that: top, cylinder body firing chamber is provided with a main spark plug and a secondary spark plug, and said two spark plugs connect same set of ignition system respectively.
Main spark plug and secondary spark plug are the spark plug of different model.
Ignition system is by a magnetogenerator flywheel, and a stator igniter and two relatively independent high pressure output devices are formed.
The beneficial effect of the utility model is: the petrol engine that adopts this model utility scheme; Because being provided with two spark plugs on top, cylinder body firing chamber lights a fire simultaneously; Shortened the flame combustion propagation length greatly, made fuel combustion more abundant, pressure of explosion is more even; Improve the complete machine output power, reduced the discharging of noxious pollutant.

Embodiment
Fig. 1, shown in Figure 2; The said single cylinder dual ignition plug of the utility model two-stroke gasoline engine comprises cylinder body 1 and piston 2, and said piston 2 is placed on cylinder body 1 inside; A main spark plug 5 and a secondary spark plug 4 are set respectively on top, cylinder body firing chamber; Said main spark plug 5 is positioned at the position of top, cylinder body firing chamber deflection suction port 9 sides, and said secondary spark plug 4 is positioned at the position of top, cylinder body firing chamber deflection relief opening 10 sides, and main spark plug 5 passes through assembling spark plug jump ring 6 above that respectively with secondary spark plug 4; High voltage wire 8 connects with stator igniter 12; For the high pressure electric leakage that prevents that stator igniter 12 from producing, assemble main spark plug cavity cap 7 at main spark plug 5 with spark plug jump ring 6 outsides, assemble secondary spark plug cavity cap 3 at secondary spark plug 4 with spark plug jump ring 6 outsides.
Shown in Figure 2 is the ignition system that the utility model single cylinder dual ignition plug two-stroke gasoline engine uses; The relatively independent high pressure output device of two covers that its formation comprises magnetogenerator flywheel 11, stator igniter 12 and is connected with stator igniter 12; Comprise 6, two high voltage wires 8 of two spark plug jump rings and main spark plug cavity cap 7 and secondary spark plug cavity cap 3.
The concrete working procedure of the utility model:
A work cycle of this motor is to be accomplished by two strokes of piston motion, when piston 2 is up, and compression top working mixture; When piston stroking upward during near top dead center, spark plug 4, spark plug 5 send electrical spark simultaneously, light compressed mixed gas; High temperature and high pressure gas after the burning expands and forces piston 2 to move down output power; When piston 2 during near lower dead center, relief opening 10, waste gas enters in the atmosphere through relief opening 10 bafflers.
In the course of the work owing to adopted two spark plugs to light a fire simultaneously; Inflammable mixture is lighted and bamboo telegraph simultaneously in the cylinder body; Shortened the flame combustion propagation length greatly, made fuel combustion more abundant, pressure of explosion is more even; Improve the complete machine output power, reduced the discharging of noxious pollutant.
Discharge capacity according to the foregoing description design is the two-stroke gasoline engine of 82.4cc; To adopting a main spark plug and adopting dual ignition plug under the throttle wide state, to carry out comparative trial; Obtained the experimental result of Fig. 3 and Fig. 4; On test data, can find out,, increase by 25.7% down at demarcation state (8000r/min) according to the two-stroke gasoline engine output power of the employing dual ignition plug of the utility model design than the existing two stroke engine that only adopts a spark plug; Fuel consumption rate also reduces by 23.4% simultaneously, has reached the effect of energy efficiency.
