The invention discloses a steam motor piston. The steam motor piston is applied to a steam motor which heats water to obtain high-temperature and high-pressure water steam so as to push a piston mechanism to move to externally output power by means of waste heat of exhaust gas exhausted by an engine exhaust pipe. The steam motor piston is cylindrical. One or more piston annular grooves are formed in the outer circumference of the side face of the steam motor piston. An axially-cylindrical upper receding counter bore is formed in the upper end face of the steam motor piston, an axially-cylindrical lower receding counter bore is formed in the lower end face of the steam motor piston, and the upper receding counter hole is communicated with the lower receding counter hole through an installation through hole. The steam motor piston is reasonable and simple in structure and capable of being applied to the steam motor which heats the water to obtain the obtain high-temperature and high-pressure water steam so as to push the piston mechanism to move to externally output the power by means of the waste heat of the exhaust gas exhausted by the engine exhaust pipe, so that recycling of exhaust gas energy is achieved, energy is saved, and the steam motor piston is environmentally friendly.
Description
Technical field
The present invention relates to engine art, particularly a kind of steam motor piston.
Background technique
Along with the concern of global various countries to climatic change, under the background in the whole society environmental quality requirement improved constantly, engine art requires increasingly to improve to the utilization ratio of the energy.At present, based on the combustion system of engine field, acted on limitedly by improvement directions such as burning optimization, the raising of corollary equipment efficiency, accessory load reductions, be necessary from frontier direction finding effective use of energy sources method more.
The waste gas that the conventional engines outlet pipe is discharged only is used to a part of residual amount of energy by exhaust-gas turbocharger, all the other most of exhaust energies are discharged atmosphere, failing to utilize the Conversion of Energy of exhaust waste gas is other available outputting powers, has caused the waste of energy.
Summary of the invention
The present invention is in order to overcome defect in above-mentioned prior art, provides a kind of rational in infrastructure simple, can realize the steam motor piston of exhaust energy recycling.
For achieving the above object, according to the invention provides a kind of steam motor piston, the water vapour of the High Temperature High Pressure that the waste gas residual heat that is applied to utilize engine exhaust pipe to discharge comes heating water to obtain promotes the move steam motor of external outputting power of piston mechanism, this steam motor piston is cylindric, and the side excircle offers one or multi-channel piston ring groove; Upper-end surface is provided with on the axial circular column counterbore of stepping down, and lower end surface is provided with under the axial circular column counterbore of stepping down, above step down counterbore and under the counterbore of stepping down by through hole is installed, be communicated with.
In technique scheme, the diameter of the counterbore of above stepping down is less than down the counterbore of stepping down.
In technique scheme, it is cylindric or coniform that through hole is installed.
Compared with prior art, the present invention has following beneficial effect: this steam motor piston structure is rationally simple, the water vapour that can be applied in the High Temperature High Pressure of utilizing waste gas residual heat that engine exhaust pipe is discharged to come heating water to obtain promotes piston mechanism and moves on the steam motor of external outputting power, to realize exhaust energy recycling, energy-conserving and environment-protective.

Embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of embodiment.It will be appreciated that, mentioned in following mode of execution of the present invention " on ", D score, " left side ", " right side ", " front " and " reverse side " all take the direction shown in Fig. 4 as benchmark, these words that are used for limiting direction are only for convenience of explanation, do not represent the restriction to the concrete technological scheme of the present invention.
As shown in Figures 1 to 4, the steam motor of applying steam motor piston of the present invention is that the water vapour of the High Temperature High Pressure by utilizing waste gas residual heat that engine exhaust pipe is discharged to come heating water to obtain promotes the piston mechanism external outputting power that moves, thereby realizes the exhaust energy recycling.Steam motor piston 1 of the present invention is cylindric, and the side excircle offers one or multi-channel piston ring groove 11, for ring installation; Upper-end surface is provided with on the axial circular column counterbore 12 of stepping down, and lower end surface is provided with under the axial circular column counterbore 13 of stepping down, and the diameter of the counterbore 12 of above stepping down is less than down steps down counterbore 13(as shown in Figure 4), and be communicated with by a cylindric or coniform installation through hole 14.
As shown in Figure 5, under installment state, pack into the cylinder sleeve 2 of steam motor of this steam motor piston 1, the interior ring plugging 21 of piston ring groove 11, the counterbore 12 of stepping down is stretched in the double-screw bolt upper end 31 of piston rod 3, and by nut 32, tightening fixingly, nut 32 just in time is positioned at the counterbore 12 of stepping down, and avoids in 1 to-and-fro motion of steam motor piston itself and miscellaneous part to interfere.In addition, the positioning part, top 33 of piston rod 3 and the adaptive plug-in mounting of installation through hole 14, to guarantee that in steam motor work, steam motor piston 1 is connected with the firm of piston rod 3; When through hole 14 is installed is cylindric, the positioning part, top 33 of piston rod 3 is also cylindric; When through hole 14 is installed is coniform, the positioning part, top 33 of piston rod 3 is also coniform, makes steam motor piston 1 be connected more firm with piston rod 3.When work, the water vapor obtained by exhaust-gas heated water will alternately promote 1 two end face to-and-fro motion of steam motor piston, and piston transfers out motion by the piston rod 3 of its connection, thereby realizes the conversion function that the waste gas residual heat Conversion of Energy is kinetic energy.
This steam motor piston structure is rationally simple, the water vapour that can be applied in the High Temperature High Pressure of utilizing waste gas residual heat that engine exhaust pipe is discharged to come heating water to obtain promotes piston mechanism and moves on the steam motor of external outputting power, to realize exhaust energy recycling, energy-conserving and environment-protective.
Above disclosed be only several specific embodiment of the present invention, still, the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
