Description
Technical field
The utility model relates to a kind of air-intake of combustion engine mechanism, the improvement of particularly a kind of overhead valve quartastroke engine chock plate admission gear.
Background technique
As everyone knows, internal-combustion engine is to be blended in mutually under the Piston Compression by fuel oil and air temperature, the pressure of mixed gas are brought up to a suitable level, to light or the mode of compression ignite takes fire and releases energy, the heat energy that burning is produced changes mechanical energy into then.Now various countries have all worked out rules to the discharging of internal-combustion engine, but these rules all are internal-combustion engine regulations just often, to internal-combustion engine when starting and no requirement (NR); Yet, during the internal-combustion engine cold start-up, because gas velocity is low, temperature is low, poor, the slow evaporation of fuel spray voltinism, be difficult to form uniform mixed gas, therefore, have to when cold start-up, increase fuel supply volume with air, form dense mixed gas, because partial combustion causes very big pollution to environment; What is more, because the user to internal-combustion engine chock plate misoperation, repeatedly starts internal-combustion engine, still can't run well, cause cylinder inner product oil too much, must can restart after the oil extraction, so not only environment is caused bigger pollution, and increase oil consumption greatly, the waste resource; The major defect of its existence has: the one, and internal-combustion engine one-shot success rate is low; The 2nd, user's operant level is required high; The 3rd, environmental pollution is serious, the oil consumption height; For this reason, many scientific research institutions, manufacturer and knowledgeable people have carried out experiment and test repeatedly, do not improve way preferably but have as yet so far.
Summary of the invention
In order to overcome the above-mentioned disadvantage that existing internal-combustion engine exists, the utility model provides a kind of simple and reasonable, use is easy to operate, chock plate is controlled automatically, internal-combustion engine one-shot success rate is high quartastroke engine self closing door mechanism.The technological scheme that its technical problem that solves the utility model adopts, it comprises Carburetor, thermal baffle, self closing door actuator, Carburetor is provided with chock plate, be connected with the air-flow connecting tube between the inner chamber of described thermal baffle and the self closing door actuator, the air-flow connecting tube is provided with one-way valve, and self closing door actuator is connected with chock plate by the air door controlling rod.
Described self closing door actuator comprises support, is arranged on air pump, torsion spring, L shaped connecting plate on the support, support is arranged on the Carburetor, the import of air pump and air-flow connecting tube join, support is provided with bearing pin, and L shaped connecting plate is hinged on the bearing pin, and torsion spring is arranged on the bearing pin, torsion spring one end is fixed on the support, the other end is fixed on L shaped connecting plate, and L shaped connecting plate one end is connected with the air door controlling rod, the other end and air pump output rod hinge connection.
After adopting said structure, in internal combustion engine start or stopping process, the chock plate of Carburetor is controlled automatically, and the success rate of internal-combustion engine one-shot is greatly improved, to user's also greatly reduction of operant level requirement; Have simple and reasonable, use easy to operate, internal-combustion engine one-shot success rate height, low in the pollution of the environment, energy utilization rate is high, low cost and other advantages.

Embodiment
Illustrated in figures 1 and 2, specific embodiments for the utility model quartastroke engine self closing door mechanism, it comprises Carburetor 14, thermal baffle 15, self closing door actuator 18, Carburetor 14 is provided with chock plate 13, be connected with air-flow connecting tube 17 between the inner chamber of described thermal baffle 15 and the self closing door actuator 18, air-flow connecting tube 17 is provided with one-way valve 16, and self closing door actuator 18 is connected with chock plate 13 by air door controlling rod 6.
Described self closing door actuator 18 comprises support 1, is arranged on air pump 2, torsion spring 4, L shaped connecting plate 5 on the support 1, support 1 is arranged on the Carburetor 14, the import of air pump 2 and air-flow connecting tube 17 join, support 1 is provided with bearing pin 20, L shaped connecting plate 5 is hinged on the bearing pin 20, torsion spring 4 is arranged on the bearing pin 20 by clip 3, torsion spring 4 one ends are fixed on the support 1, the other end is fixed on L shaped connecting plate 5, L shaped connecting plate 5 one ends are connected with air door controlling rod 6, and the other end is hinged with air pump output connecting rod 19 by hinge 21; In order to reduce and L shaped connecting plate 5 frictions, also be provided with felt pad 8, plastic washer 9 and pin sleeve 10 on the bearing pin 20; In order to determine the position of L shaped connecting plate 5 on support 1, also be provided with plain washer 12 and split washer 11 on the bearing pin 20; Be connected reliably with L shaped connecting plate 5 in order to ensure air door controlling rod 6, on air door controlling rod 6, be provided with air door controlling rod sheath 7.
When using, the utility model is connected with the suction port of body of the internal-combustion engine, when the internal-combustion engine rotation work, negative pressure in the internal-combustion engine casing changes, this negative pressure is connected with one-way valve 16 by the interface and the air-flow connecting tube 17 of thermal baffle 15, when the casing negative pressure reaches certain limit, also can instantaneously reach, one-way valve 16 is opened with air pump 2 to communicate, air pump 2 is under the effect of negative pressure, make the elastomer diaphragm drive air pump output connecting rod 19 in the air pump 2 produce mobile, air pump output connecting rod 19 drives L shaped connecting plate 5 and rotates around bearing pin 20, L shaped connecting plate 5 drives air door controlling rod 6 and chock plate 13 clockwise rotates, and open chock plate 13 on the Carburetor 14, and motor is normally started working, and meanwhile torsion spring 4 is reversed.
When engine shutdown; because the negative pressure in the internal-combustion engine casing returns to normal state; negative pressure during air pump 2 proper functioning also returns to normality; under the twisting force of torsion spring 4; elastomer diaphragm in the air pump 2 resets; torsion spring 4 promotes L shaped connecting plate 5 simultaneously, and L shaped connecting plate 5 drives air door controlling rod 6 and chock plate 13 rotates counterclockwise, and makes the chock plate 13 on the Carburetor 14 get back to closed condition.
