Embodiment 1

[0041] Such as figure 1The liquid-occupied suspension piston engine shown includes a cylinder 1 and a piston 2, the top dead center 21 on the cylinder 1 corresponding to the top dead center of the piston 2 and the bottom dead center of the piston 2 In the entire stroke range between the bottom dead center 22 on the cylinder 1 corresponding to the point, the piston 2 is non-contact suspended with the cylinder 1, and the piston 2 corresponding to the top dead center of the piston 2 A liquid channel 7 is provided on the cylinder side wall 201 corresponding to the suspension section of the piston 2 below the top dead center 21 on the cylinder 1, and the liquid channel 7 communicates with the liquid source 6 through a high-pressure liquid pump 30, wherein the The liquid in the liquid source 6 is water.

[0042] In each stroke of the movement of the piston 2, through experiments or / and theoretical calculations, adjust the size of the gap 33 between the piston 2 and the cylinder 1 f...

Embodiment 2

[0047] like figure 2 The difference between the liquid-occupied suspended piston engine shown in Embodiment 1 is that the liquid source 6 communicates with the high-pressure liquid pump 30 through the cooling system 20 of the liquid-occupied suspended piston engine. A timing control device is provided between the source 6 and the liquid channel 7 .

[0048] The liquid in the liquid source 6 first passes through the cooling system 20 to cool the liquid-occupied suspended piston engine, and then is pumped into the gap 33 by the high-pressure liquid pump 30 .

[0049] In this embodiment, the timing control device is a solenoid valve timing control device 5 , and the solenoid valve timing control device 5 is arranged between the liquid passage 7 and the high-pressure liquid pump 30 .

[0050] Optionally, the cooling system 20 can also be located between the high-pressure liquid pump 30 and the liquid passage 7; the timing control device can also be arranged between the high-pres...

Embodiment 3

[0052] like image 3 The liquid occupancy suspended piston engine shown differs from Embodiment 2 in that: the outer surface of the piston 2 is fixedly connected with a piston heat insulating layer 32, and the inner top wall and the inner side wall of the piston 2 are provided with The piston heat insulation interlayer 31; the cylinder inner wall of the cylinder 1 is fixedly connected with a cylinder heat insulation layer 42, and the outer wall is provided with a cylinder heat insulation interlayer 41.

[0053] The purpose of setting the heat insulation structure of the piston is to reduce heat loss, and similarly, the setting of the heat insulation structure of the cylinder is also to reduce heat loss. The so-called heat insulation interlayer refers to the vacuum structure arranged inside the cylinder or the piston, which is also used to reduce heat loss.

[0054] Selectively, it is also possible to fixedly connect the piston heat insulation layer 32 only on the outer surfac...

Abstract

The invention discloses a liquid occupation suspension piston engine, which comprises an air cylinder and a piston, wherein the piston and the air cylinder are arranged in a non-contact suspension way in an entire stroke range or a part of the stroke range between an upper dead point on the air cylinder which corresponds to an upper piston dead point of the piston and a lower dead point on the air cylinder which corresponds to a lower piston dead point of the piston; an air cylinder side wall which corresponds the suspension section of the piston below the upper dead point on the air cylinder which corresponds to the upper piston dead point of the piston and / or the piston suspension section side wall of the piston is provided with a liquid channel; and the liquid channel is communicated with a liquid source through a high-pressure liquid pump. According to the liquid occupation suspension piston engine, an engine piston and the air cylinder can be sealed without being worn in a high temperature state, the heat efficiency is increased while nitrogen oxide is reduced, and the consumption of fuel is lowered, so that the engine efficiency is increased, energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a suspended piston engine. Background technique [0002] Since the birth of the engine, the high-efficiency sealing of the engine combustion chamber has always been the top priority pursued by the developers and manufacturers of the engine. The setting of the piston ring lubricated by oil between the piston and the cylinder liner of the modern engine makes the gap between the piston and the cylinder liner This structure does greatly improve the sealing performance of the engine, but due to the sliding friction between the cylinder liner, piston and piston ring, the requirements for the material of the piston, piston ring, especially the cylinder liner are quite high. Performance, in order to maintain the sealing of the engine, the continuity of the sealing and the life of the engine, the cylinder liner made of high wear-resistant material must be used and lubricated with o...
