Problems solved by technology

In the structure of traditional engines, this temperature cannot be raised any further, otherwise problems such as oil deterioration, cylinder liner melting, and piston heat loss may occur.
However, as we all know, in order to maintain this lower temperature between the piston and the cylinder liner, the engine will be forced to cool so that about 30% of the energy of the fuel will flow out through the cylinder liner, piston and cylinder head, forming a low-value engine with little value. Quality waste heat

Embodiment Construction

[0051] Such as figure 1 The suspended piston engine shown includes a cylinder 1 and a piston 2, and the piston 2 is wholly or partially arranged in the cylinder 1, and the top dead center of the cylinder 1 corresponding to the piston top dead center of the piston 2 The piston 2 and the cylinder 1 are non-contact suspended in the entire stroke range or part of the stroke range between the point 121 and the bottom dead center 122 on the cylinder 1 corresponding to the piston bottom dead center of the piston 2 Or a quasi-floating setup.

[0052] Such as figure 2 and image 3 In the suspension piston engine shown, the piston 2 is composed of a piston suspension section 201, a piston sealing section 202 and a piston power section 203, the piston suspension section 201 is connected with the piston sealing section 202, and the piston sealing section 202 is connected with the piston sealing section 202. The piston power section 203 is connected, the length of the piston suspension...

Abstract

The invention discloses a suspended piston engine which comprises a cylinder and a piston, wherein the piston is entirely or partially arranged in the cylinder, and the piston and the cylinder are arranged in a noncontact suspension or quasi suspension way within an entire travel range or a partial travel range between an upper dead point on the cylinder corresponding to the upper dead point of the piston and a lower dead point on the cylinder corresponding to the lower dead point of the piston. The invention can realize the sealing and no abrasion of an engine piston and a cylinder sleeve inthe state of high temperature, thereby improving the efficiency of the engine.

Description

technical field [0001] The invention relates to the field of engines. 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 oil, which determines that the working temperature of the engi...
