Abstract
The utility model discloses a powder fuel piston IC engine, which is provided with a solid powder fuel container, and a solid powder fuel feeding passage provided with a control structure is arranged between the solid powder fuel container and a cylinder. The internal combustion engine of the utility model can simultaneously use fuel oil and solid powder fuel, and can also use solid powder fuel or fuel oil separately. Therefore, the utility model has the advantages that the application range is wide, the operation is easy, and the powder fuel piston IC engine can use many kinds of fuel resources.
Description
The utility model relates to a kind of internal-combustion engine, especially a kind of internal-combustion piston engine that uses powdered fuel.
Existing internal-combustion piston engine generally is made of cylinder, piston, connecting rod, bent axle, intake valve, exhaust valve and liquid fuel tank and liquid fuel passage.Its liquid fuel that uses is generally diesel oil or gasoline.In addition,, in the existing internal-combustion engine of part, also be provided with the ignition mechanism that is used to light a fire, it typically is electric plug for promoting oil inflame, being convenient to engine starting.Because world petroleum resource is poor day by day, the phenomenon of fuel oil shortage happens occasionally.If can with of a great variety, have a very wide distribution, resource replaces than the solid fuel (as coal, flammable grass, wood or other foreign material) of horn of plenty or part replaces the fuel of fuel oil as internal-combustion engine, the imbalance between supply and demand of fuel oil will be alleviated greatly, and fuel cost might be reduced.
The purpose of this utility model provides a kind of internal-combustion piston engine of burning powdered fuel.
The working principle of the utility model internal-combustion engine and existing piston type oil-burning internal combustion engine are identical, promptly still have air-breathing, compression, acting, four strokes of exhaust.In the utility model, except that the structural type of cylinder, piston, connecting rod, bent axle, intake valve and the exhaust valve of still continuing to use existing internal-combustion engine, also be provided with powdered fuel case and powdered fuel feed pipe especially.The powdered fuel case is connected with cylinder of internal-combustion engine by the pressed powder feed pipe.For control inlet amount and feed time, make fuel enter cylinder in suction stroke, prevent that simultaneously cylinder combustion gas from oppositely entering fuel tank from feeding-passage, is provided with the charging control structure between feeding-passage and cylinder.The charging control structure can adopt the baffle-type feeding gate that opens and closes with internal combustion engine intake valve interlock, control feeding-passage simply, makes fuel suck cylinder with air when suction stroke.The charging control structure also can adopt the high pressure dispensing system similar to existing oil-burning internal combustion engine injection system, promptly utilizes high-pressure service pump and nozzle that pulverized fuel is sprayed into cylinder combustion.When adopting the charging control structure that constitutes by parts such as high-pressure service pump and charging nozzles, powdered fuel is fully mixed with air, thereby make its burning more complete, swift and violent.In the utility model, similar to existing internal-combustion engine for ease of engine starting, promote fuel combustion, also can be in body relative set electric plug or other igniting combustion supporting device.Certainly,,, when not needing igniting combustion supporting device is set, can not be provided with the requirement of internal-combustion engine operating conditions according to the combustion characteristic of using fuel or user yet.In addition, also can consider in the utility model internal-combustion engine to be provided with and the fuel tank of existing oil-burning internal combustion engine structural similarity and corresponding fuel path system, as transport pipe, oil injecting nozzle etc.In the utility model, for the pressed powder internal-combustion engine that fuel oil supply system is not set,, therefore the combustion performance of using pulverized fuel is had relatively high expectations because it only uses powdered fuel to drive, its suitable fuel scope relative narrower, but its structure is comparatively simple.For the powdered fuel supply system both is set, the internal-combustion engine of fuel oil supply system is set again owing to have a fuel oil auxiliary combustion, its to the combustion performance of using pulverized fuel require relatively low.Simultaneously, when no powdered fuel or when not having fuel oil, it is emergent also can only to use a kind of fuel.Therefore, though the structure relative complex of this type powdered fuel internal-combustion engine some, but its suitable fuel wider range, be suitable for especially more in the kind of powdered fuel, combustion performance is relatively poor relatively or use in the unsettled area of fuel supply (as mountain area, rural area etc.).The powdered fuel that the utility model internal-combustion engine is used can be coal dust, flammable grass, wood chip or its mixture.For improving the combustion performance of powdered fuel, also can in pulverized fuel, add an amount of chemical combustion improver, as potassium nitrate, gunpowder etc., make it violent burning, produce high-pressure hot gas, become the fuel that can drive internal combustion engine.
Because internal-combustion engine of the present utility model both can use fuel oil and powdered fuel simultaneously, can independently use powdered fuel or fuel oil again, therefore have wide application, easy to use, can make full use of the pluralities of fuel characteristics of resources.
Content of the present utility model illustrates further in conjunction with the embodiments.
Fig. 1 is the structural representation of internal-combustion engine among the embodiment.
As shown in Figure 1, internal-combustion engine has cylinder 1, piston 2, connecting rod 3, bent axle 4, gas-entered passageway 6, intake valve 7, exhaust passage 13 and exhaust valve 14 in the present embodiment.For using powdered fuel, in body, be provided with powdered fuel case 12 and pulverized fuel path 10 especially, link by path 10 between pulverized fuel case 12 and the cylinder 1.In the present embodiment, charging control structure has adopted the baffle-type feeding gate 11 that opens and closes with intake valve 7 interlocks, control feeding-passage 10 simply.Baffle-type feeding gate 11 is arranged at the ingress of feeding-passage 10.Enter feeding-passage 10 for ease of powdered fuel,, funnel shape is arranged in the bottom of the fuel tank 12 in the present embodiment.In addition, be provided with the electric plug 5 that is used for igniting combustion supporting in the internal-combustion engine of present embodiment.When internal-combustion engine is in air-breathing kind of journey, intake valve control cam 9 jack-up intake valves 7.Because feeding gate 11 and intake valve 7 interlocks will be so feeding gate 11 will be opened simultaneously with intake valve 7.By the motion of piston 2, make air and fuel suck cylinder 1 by gas-entered passageway 6 and feeding-passage 10 respectively.To the suction stroke end, intake valve control cam 9 is jack-up intake valve 7 no longer, and under the effect of intake valve Returnning spring 8, intake valve 7 and feeding gate 8 are closed simultaneously, and internal-combustion engine enters compression stroke, expansion stroke and exhaust stroke successively.When exhaust stroke, exhaust valve control cam 16 jack-up exhaust valves 14, the waste gas in the cylinder 1 is 13 discharges from the exhaust passage.Finish up to exhaust stroke, exhaust valve control cam 16 loosens exhaust valve 14, makes it to close under the effect of exhaust valve Returnning spring 15.After this, internal-combustion engine reenters suction stroke.Four stroke cycle are reciprocal thus.
