Description
Technical field
The present invention 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, therefore need a kind of new work engine of invention can make cylinder liner and piston proper functioning at high temperature.
Summary of the invention
Non-contact suspension setting of the present invention is meant and neither comes in contact and keep quite little gap between the cylinder and piston, thus the purpose that realization not only seals but also do not wear and tear.The so-called accurate setting that suspends is meant and is in contact and non-contacting threshold state between piston and the cylinder, so just can further improve sealing, Wear again.The purpose of piston insulating layer structure setting is in order to reduce heat loss, and in like manner, the setting of cylinder heat-insulating structure also is in order to reduce heat loss.The setting of cylinder fluid passage and piston fluid passage be for suitable cooling and the uniformity by the flowing medium holding temperature in the incoming fluid passage to reduce cold and hot deformation, keep the high-seal of piston and cylinder.In order further to improve the efficient of motor, reduce the heat loss of traditional cylinder head, an embodiment among the present invention discloses a kind of suspended piston opposite disposed sliding cylinder distribution engine, there is not cylinder head in the motor of this structure, two cylinder sleeve end opposite disposed, end interface place two cylinder opposite disposed is provided with intake duct and air outlet flue, and distribution is slided by cylinder and realized.When exhaust stroke begins, one or two cylinder begins to slide simultaneously, break away from end and another cylinder, thereby two cylinders are opened simultaneously, and while and intake duct, air outlet flue is communicated with, in this structure, if the intake and exhaust group of flow fields is woven, or compressor turbine is set on intake duct, and on air outlet flue, establish power turbine, and two turbines are coaxial, so just can make blast air to air outlet flue, fresh air is pressed in the cylinder by gas compressor, and in this structure, engine spark plug and/or engine fuel injection device can be arranged on the cylinder wall side and the portion cooling channel of setting a trap in spark plug and/or fuel injector and cylinder sidewall contacting point.For piston can better be suspended in the cylinder, the invention also discloses a kind of magnetic suspension and a kind of gas (vapour) suspension structure, its purpose is to make the piston can be at magnetic force or gas pressure low suspension in cylinder, only moves reciprocatingly by the cylinder axial direction and does not contact with cylinder sidewall.
