Abstract

The utility model relates to a piston. The utility model is characterized in that a piston ring is obtained by the overlapping of rings in an internal combustion engine cylinder, and a sealed and closed thin circular ring is arranged on the upper side face of the piston ring of a piston body. The utility model can avoid effective gas from leaking and thrusting into the body from the piston ring gaps, the hermetic effect is good, the wear to the cylinder body is small, the working power and the service life of the internal combustion engine can be improved, the energy can be saved obviously, the oil consumption can be reduced, the waste gas discharge can be reduced, and the environmental pollution caused by the waste gas can be reduced. The utility model has the advantages of simple and compact structure, high safety, easy fabrication and installation, convenient and flexible maintenance, low cost, etc.

Description

Energy-saving piston

The utility model relates to the piston, particularly energy-saving piston that passes through the overlapping acquisition piston ring of ring in the cylinder of internal combustion engine.

Piston ring on the at present existing cylinder of internal combustion engine inner carrier, must need certain clearance owing to expand with heat and contract with cold, ubiquity effectively, and combustion gas spills from piston ring gap, caused the power decline of internal-combustion engine to reduce, combustion gas is poured internal body downwards from piston ring gap and is caused deterioration of lubricant, combustion gas simultaneously also can be poured cylinder with the lubricant oil rising and cause fuel fully not burn, the waste gas black smoke that is produced is bigger, fuel consumption is increased, wasted the energy, cause discharge amount of exhaust gas to increase, befouling environment is comparatively serious, for the gap of control piston ring has the multilayer of employing ring overlapping, expansion loop, many-sided technology such as spring support tensioner ring, sealing effect is also better, power of IC engine also increases, energy fuel consumption also descends, but the wearing and tearing of piston countercylinder body increase simultaneously, causes the also degradation shortcoming of descending of service life of engine, for overcoming above-mentioned existing deficiency, the utility model has designed energy-saving piston.

The purpose of this utility model provides piston ring gap hermetically enclosed, improve the power and the service life of engine of internal-combustion engine, make fuel combustion abundant, save and save the energy, it is obvious to reduce fuel consumption, reduce discharge amount of exhaust gas, alleviate the waste gas environmental pollution, to the little energy-saving piston of cylinder block wearing and tearing.

The utility model is achieved in that to install on the piston ring upper side in the piston body piston groove to have hermetically enclosed book annulus, the gap on the hermetically enclosed book annulus closed piston ring.

The utility model has been avoided effective combustion gas to spill from piston ring gap and has been poured body, hermetically enclosed effective, little to the cylinder block wearing and tearing, increased the working pressure of cylinder, the working power and the service life of engine of internal-combustion engine are greatly improved, make fuel combustion abundant, saved the energy, it is obvious to reduce fuel consumption, reduced the exhaust gas discharging amount, avoided the generation of black smoke, alleviated the pollution of waste gas environment, have simple and compact for structure, safe and reliable, be easy to manufacturing and install, and easy to maintenance flexible, be easy to apply advantage such as with low cost.

Concrete structure of the present utility model and embodiment are provided by the following drawings.

Fig. 1 is a general structure schematic representation of the present utility model.

To be described in further detail concrete structure of the present utility model and embodiment below in conjunction with accompanying drawing.

Shown in accompanying drawing 1: installation has hermetically enclosed book annulus 2, the gap on the hermetically enclosed book annulus 2 closed piston rings 3 on piston ring 3 upper sides in piston body 1 piston groove.

Claims

1, energy-saving piston, it is made up of piston body (1), piston ring (3), it is characterized in that: have hermetically enclosed book annulus (2), the gap on hermetically enclosed book annulus (2) the closed piston ring (3) on piston ring (3) upper side in piston body (1) piston groove.
