Abstract
The invention discloses a suspension piston motor which comprises an air cylinder and a piston. The piston is arranged in the air cylinder in a sliding and matched mode. The piston is in non-contact suspension arrangement or ready suspension arrangement with the air cylinder in a 1/4 stroke near a top dead center. According to the suspension piston motor, the motor piston and an air cylinder sleeve can be sealed in the high temperature stage without abrasion and motor efficiency is improved.
Description
Technical field
the present invention relates to engine art, relate in particular to a kind of engine with suspension piston.
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 cylinder liner, make slipper seal between piston and cylinder liner, this structure has increased substantially the sealing of motor really, but owing between cylinder liner and piston and piston ring, having sliding friction, for piston, the piston ring especially material requirements of cylinder liner has quite high wear-resisting property, in order to maintain 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, the operating temperature that has so just determined air cylinder sleeve of engine and piston must remain on reduced levels (Modern Engine is between 400～500 ℃).In the structure of conventional engines, this temperature can't improve again, otherwise the problems such as machine oil is rotten, cylinder liner fusing, piston heat waste just may occur.Yet, well-known, in order to maintain this lower temperature between piston and cylinder liner, will be forced the energy of cooling so that fuel 30% left and right to flow out by cylinder sleeve, piston and cylinder cap to motor, form the little low-quality waste heat of value.If we can avoid or reduce the heat that flows out cylinder sleeve, piston and cylinder head, we just can increase substantially the efficiency of motor.If this problem is resolved, the efficiency of motor almost can significantly improve, the key addressed 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 in the condition of high temperature between engine piston and cylinder liner, therefore need a kind of new work engine of invention can make cylinder liner and piston at high temperature work.
Summary of the invention
in order to overcome the above-mentioned defect of conventional engines, the invention discloses a kind of engine with suspension piston.
the object of the present invention is achieved like this: a kind of engine with suspension piston, comprise cylinder and piston, described piston is located in described cylinder with being slidably matched, and described piston is that the non-contact suspension arranges or the accurate setting that suspends with described cylinder in close 1/4 stroke of its top dead center.
a kind of engine with suspension piston, comprise cylinder and piston, described piston is arranged in described cylinder with being slidably matched, and described piston comprises that described suspension section height is not more than 1/4 of described piston stroke near the seal section of the suspension section of described piston crown and close described piston base.
non-contact suspension setting of the present invention refers between cylinder and piston and neither comes in contact and maintain quite little gap, thereby realizes the purpose that not only seals but also do not wear and tear.So-called accurate suspend to arrange refer between piston and cylinder and so just can further improve sealing, Wear again in contact and non-contacting threshold state.
the present invention has following actively useful effect:
1, the present invention is simple in structure, volume is little, adult is cheap;
2, the present invention can realize that engine piston and cylinder liner can not only seal but also do not wear and tear under the condition of high temperature, thereby improves engine efficiency.
, motor disclosed in this invention the operating temperature at cylinder, piston and other interface, firing chamber can reach quite high temperature, situation about even allowing at material is issued to the flame combustion chamber temperature, therefore can increase substantially engine thermal efficiency.
The accompanying drawing explanation
the structural representation that Fig. 1 is the embodiment of the present invention 1;
the structural representation that Fig. 2 is the embodiment of the present invention 2.
accompanying drawing number
1 cylinder, 2 pistons, 101 suspension sections, 102 seal sections, 121 top dead centers, 122 lower dead center.
Embodiment
embodiment 1
engine with suspension piston as shown in Figure 1, comprise cylinder 1 and piston 2, and described piston 2 is located in described cylinder 1 with being slidably matched, and described piston 2 is that the non-contact suspension arranges with described cylinder 1 in close 1/4 stroke of its top dead center 121;
selectable, described piston 2 is arranging near being as the criterion to suspend with described cylinder 1 in 1/4 stroke of its top dead center 121.
engine with suspension piston as shown in Fig. 2, comprise cylinder 1 and piston 2, described piston 2 is arranged in described cylinder 1 with being slidably matched, described piston 2 comprises that the height of described suspension section 101 equals described piston 2 at 1/4 of described cylinder 1 stroke near the seal section 102 of the suspension section 101 of described piston 2 heads and close described piston 2 bottoms.
selectable, the height of described suspension section 101 is less than described piston 2 at 1/4 of described cylinder 1 stroke.
Obviously, the invention is not restricted to above embodiment, according to known technology and the technological scheme disclosed in this invention of related domain, can derive or association goes out many flexible programs, all these flexible programs, also should think protection scope of the present invention.
