Description

Engine with air-suspending sealing ring

Technical field

The utility model relates to engine art.

Background technique

Since motor is born, the efficient sealed of engine chamber is the developer of motor and the most important thing that MANUFACTURER is pursued always, pass through the setting of oil lubricating piston ring between modern engine piston and the cylinder liner, make slipper seal between piston and the cylinder liner, this structure has increased substantially the sealing of motor really, but owing to have sliding friction between cylinder liner and piston and the piston ring, for piston, the piston ring especially material requirements of cylinder liner has quite high wear-resisting property, in order to keep the sealing of motor, the cylinder liner that the persistency of sealing and engine life just must adopt high abrasion resisting material to make, and adopt machine oil to be lubricated, so just determined the operating temperature of air cylinder sleeve of engine and piston must remain on reduced levels (modern motor is between 400～500 ℃).This temperature can't improve again in the structure of conventional engines, otherwise problems such as machine oil is rotten, cylinder liner fusing, piston heat waste just may occur.Yet well-known, in order to keep this lower temperature between piston and the cylinder liner, will forcing to cool off consequently to motor, the energy of fuel about 30% will flow out the little low-quality waste heat of formation value by cylinder sleeve, piston and cylinder cap.If we can avoid or reduce the heat that flows out cylinder sleeve, piston and cylinder head, we just can increase substantially the efficient of motor.If this problem is resolved, the efficient of motor almost can significantly improve, the key that addresses this problem just must make the heat resistance at envelope interface, firing chamber (be cylinder envelope interface, be cylinder, piston and cylinder head in conventional engines) increase substantially.In order to realize this purpose, must solve can not only seal but also problem that can heavy wear between engine piston and cylinder liner in the condition of high temperature.For this reason, the utility model people applied for engine with suspension piston (number of patent application: 200910143200.1), yet, the machining accuracy that the suspension setting between piston and the cylinder is had relatively high expectations, and thermal compensation is poor.Therefore, also need to invent a kind ofly have that better thermal compensation, requirement on machining accuracy are low, good airproof performance and piston and the discontiguous new work engine of cylinder.

Summary of the invention

For piston can better be suspended in the cylinder under gas pressure, only move reciprocatingly and do not contact with cylinder sidewall by the cylinder axial direction, the utility model discloses a kind of air-suspending sealing ring structure.The utility model is by being provided with the gas suspension seal ring on piston, air pressure is set on the gas suspension seal ring scolds wall construction or air pressure to scold the wall open channel, be implemented in that the gas suspension seal ring is radially shrinking under the gas pressure, disengage thereby make between gas suspension seal ring and the cylinder liner, and then alleviate frictional loss greatly, and can increase substantially the operating temperature of outer wall of combustion chamber such as cylinder liner, piston, finally improve the purpose of engine efficiency.For the gas suspension seal ring is broken away from and the contacting of cylinder liner, need the gaseous pressure source, the gaseous pressure source can be supplied with by cylinder is outside, be source of high pressure air, high-pressure water vapor source or high-pressure water, wherein the high pressure water in the high-pressure water is through piston vaporization chamber or cylinder vaporization chamber, form high-pressure water vapor by vaporization in piston vaporization chamber or cylinder vaporization chamber, in order to promote gas suspension seal ring radial contraction.Gaseous sources also can be by supplying with in the cylinder, utilize the high pressure that forms in the engine combustion process to inflate to the high cylinder pressure air storing cavity that is located at the piston high-pressure gas chamber on the piston or be located on the cylinder, because piston high-pressure gas chamber and cylinder high-pressure gas chamber have certain volume, so have the effect of energy storage.Therefore, can be for the gas suspension seal ring provide radial compression gas phase power in motor low pressure event such as suction stroke, exhaust stroke, being provided with of check valve will more help the realization of this process.Even yet do not establish check valve, still can realize this process by the volume of adjusting piston high-pressure gas chamber and cylinder high-pressure gas chamber and the size of adjusting respective channel.The essence of this process is the gas oscillating process, the purpose of piston pressure-releasing chamber setting is to provide compressed space in order to be in the high-pressure process (be engine compresses stroke later stage, blast and expansion stroke early stage) in the firing chamber for the seal ring backside gas, (being motor suction stroke, exhaust stroke later stage) imports the firing chamber with the air in the piston pressure-releasing chamber in the low pressure event and when the firing chamber is in, circulation vibration so repeatedly, keep seal ring and cylinder wall disengages, keep the gas suspension state.In the structure that is provided with suspension gas cylinder channel, the gas suspension seal ring needs up and down two ends all to establish air pressure to scold wall construction.

So-called radial component face is exactly to produce the face that radial component makes gas suspension seal ring generation radial contraction under gas pressure, is generally the conical surface.The purpose that radial component face gas suspension seal ring is set is both to have realized effectively in order to satisfy that the disengaging of gas suspension seal ring and cylinder wall is in state of suspension, guaranteed that again the gap between the cylinder and piston is unlikely to excessive requirement.This radial component face gas suspension seal ring must have certain centrifugal direction elasticity, in order to make the gas suspension seal ring have the elasticity of centrifugal direction, the gas suspension seal ring can be made and not have a mouthful formula radial component face gas suspension seal ring, opening one-part form radial component face gas suspension seal ring or multi-section type radial component face gas suspension seal ring, two or more opening one-part form radial component face gas suspension seal rings radially mismatch suit constitute radially combined type gas suspension seal ring of opening, when assembling, the opening of different rings answers misorientation to install, for example, the opening of two trip rings forms 180 ° mutually, and the opening of three trip rings forms 120 ° mutually.The gas suspension seal ring of above-mentioned several forms all can use separately or a plurality of of the same type or dissimilar gas suspension seal rings are axially fallen to adorning use.All can not constitute and promptly be called own elasticity gas suspension seal ring for having mouthful formula gas suspension seal ring and open type gas suspension seal ring by ring self elasticity; In the gas suspension seal ring structure of multi-section type (being many mouthfuls of formulas), just must apply elastic force from inside to outside, applying of this elastic force can solve by spring structure, also can apply the elastic force that certain gaseous pressure makes it to form on the centrifugal direction by the inboard at the multistage ring and solve.Wherein, pneumatic elasticity formula gas suspension seal ring more is applicable to the hot environment in the cylinder.

In order further to improve the efficient of motor, reduce the heat loss of traditional cylinder head, the utility model discloses a kind of structure that thermal-protective coating is set on piston or cylinder.Simultaneously, for suitable cooling and the uniformity by the flowing medium holding temperature in the incoming fluid passage to reduce cold and hot deformation, the high-seal that keeps piston and cylinder, the utility model also announced a kind of cylinder or (with) structure of cylinder fluid passage and piston fluid passage is set in the piston.In above-mentioned two kinds of structures, engine spark plug or (with) the engine fuel injection device can be arranged on the cylinder wall side, and spark plug or (with) fuel injector and the cylinder sidewall contacting point portion cooling channel of setting a trap.
