Abstract
The utility model relates to a varactor internal-combustion engine. The utility model mainly solves the technical problems of the existing internal-combustion engine that expansion work is not complete, heat energy utilization is low, and the like. The essential of the technical scheme is as follows: an air cylinder bed is connected with a crankcase into an integrated outer casing; a piston is matched and sleeved in an air cylinder; a crankshaft crank is connected with the piston by a connecting rod; an air exhaust valve is matched with and sleeved on an air exhaust hole on the upper part of the air cylinder; an air exhaust pipe is communicated with the air exhaust hole on the upper part of the air cylinder; the lower waist of the air cylinder is provided with an air inlet hole, and the air inlet hole is provided with an air inlet cavity on a corresponding position; and the outer side of the air inlet cavity is provided with an air inlet pipe communicated with the air inlet cavity. The utility model changes the original internal-combustion engine, shifts the air inlet hole from the upper part to the lower part, makes the volume before compression of the air cylinder be less than the volume after expansion by controlling the air exhaust valve, then ensures thorough expansion work, makes heat amount brought by waste air be 31 to 36 percent of the total heat amount, and then can enhance the energy utilization by more than 38 percent.
Description
Technical field
The utility model relates to a kind of internal-combustion engine.
Background technique
At present, the volume of cylinder before the common internal combustion engine compression with expand after volume of cylinder constant, so it expands acting not thorough, be cooled system and waste gas of the available heat energy of some has been taken away, and has caused the significant wastage that can utilize heat energy.
Summary of the invention
The purpose of this utility model provides a kind of internal-combustion engine is cooled this positive-displacement internal combustion engine that partly can utilize heat energy utilization to get up that system and waste gas takes away.
The technological scheme that its technical problem that solves the utility model adopts is: it is to be connected into monolithic case by cylinder gasket 1 and crankcase 8, engage sleeves is equipped with piston 2 in cylinder, crankshaft crank 11 links by connecting rod 7 and piston 2, engage sleeves is equipped with outlet valve 4 on the cylinder upper discharge hole, outlet pipe 5 links with the exhaust port on cylinder top, following waist at cylinder and cylinder gasket 1 is provided with inlet hole, and be provided with air-inlet cavity 6 in the corresponding position of inlet hole, in the arranged outside of air-inlet cavity 6 and the suction tude that links 13 that has.Or be respectively arranged with inlet hole and air-inlet cavity 6 in 2 sides of the following waist of cylinder 1, respectively with about 2 air intake branches 13 of linking of 2 air-inlet cavitys 6 link with main tracheae.The lower end mouth of air-inlet cavity 6 is concordant in the piston lower dead center 12 of cylinder 1 operation with piston 2; The upper end-hole of air-inlet cavity 6 is in below 3/4 position of effective cylinder volume.
The beneficial effects of the utility model are: volume of cylinder and the volume of cylinder after the expansion before the common internal combustion engine compression are constant, acting is not thorough so it expands, be cooled system and waste gas of the available heat energy of some about about 60% is taken away and has been caused the significant wastage that can utilize heat energy, the utility model is by former internal-combustion engine is transformed, design the internal-combustion engine that can change volume of cylinder, promptly by inlet hole is moved to the bottom from top, and by controlling the volume after outlet valve makes the preceding volume of cylinder compression less than expansion, the heat that waste gas is taken away only accounts for the 31-36% of total amount of heat, thereby can improve capacity usage ratio more than 38%.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-cylinder and cylinder gasket, 2-piston, 3-piston top dead center, 4-outlet valve, 5-outlet pipe, 6-air-inlet cavity, 7-connecting rod, 8-crankcase, 9-crankcase link, 10-crankshaft center, 11-crank, 12-piston lower dead center, 13-air intake branch.
Embodiment
The utility model is to be connected into monolithic case by cylinder gasket 1 and crankcase 8, engage sleeves is equipped with piston 2 in cylinder, crankshaft crank 11 links by connecting rod 7 and piston 2, engage sleeves is equipped with outlet valve 4 on the cylinder upper discharge hole, outlet pipe 5 links with the exhaust port on cylinder top, following waist at cylinder and cylinder gasket 1 is provided with inlet hole, and is provided with air-inlet cavity 6 in the corresponding position of inlet hole, at the arranged outside of air-inlet cavity 6 and the air intake branch that links 13 that has.The utility model also can be respectively arranged with inlet hole and air-inlet cavity 6 in 2 sides of the following waist of cylinder 1, respectively with about 2 air intake branches 13 of linking of 2 air-inlet cavitys 6 link with main tracheae.Air-inlet cavity 6 the position is set: the lower end mouth of air-inlet cavity 6 and piston 2 are concordant in the piston lower dead center 12 of cylinder 1 operation; The upper end-hole of air-inlet cavity 6 is in below 3/4 of effective cylinder volume, and described actual volume is meant the interior empty volume of cylinder when piston moves to lower dead center, and comprises the bags.
The utility model is by former internal-combustion engine being transformed, designed the internal-combustion engine of cylinder-variable volume, promptly by inlet hole is moved to the bottom from top, and before making the cylinder compression by the control outlet valve volume less than the volume after expanding.When piston moved, descent of piston began air inlet during to inlet hole, and exhaust port is opened simultaneously, descent of piston during to lower dead center air inlet finish.After bent axle turned over again, piston began upwards operation, went upward to residual volume and had only 1/4 place, exhaust valve closing, beginning compression stroke.Move to top dead center commencement of fuel injection before, its injection advance angle is consistent with old-fashioned internal-combustion engine with the petrol engine ignition advance angle; The working stroke that expands then begins, and when descent of piston to 3/4 actual volume line was following, inlet hole began air inlet, so far, also just enters next cyclic process, and therefore, this internal-combustion engine is one circulations of two strokes, can improve capacity usage ratio more than 38%.Consult Fig. 1.
