Abstract

The invention discloses a free piston type engine with a piston guiding device, which comprises the free piston type engine which consists of a hydraulic pump body component, a first cylinder and a second cylinder, wherein the first cylinder and the second cylinder are respectively connected with two sides of the hydraulic pump body component; an inner piston component and an outer piston component are respectively mounted in the first cylinder and the second cylinder; and the outer piston component comprises a first outer piston and a second outer piston, a first piston pin is arranged at the tail part of the first outer piston far away from the hydraulic pump body component, and a second piston pin is arranged at the tail part of the second outer piston far away from hydraulic pump body component. According to the invention, the engine has the benefits that interactive lateral force is formed between the side surfaces of the pistons and the cylinder walls, so as to reduce the friction between the pistons and the cylinder walls; and in case of the deformation of the piston pins under the performance loading of the engine, piston guide posts can provide the correct direction of the pistons in the air cylinders.

Description

technical field [0001] The invention relates to a free-piston engine, in particular to a free-piston engine provided with a piston guiding device. Background technique [0002] Conventionally, the movement of the piston in an internal combustion engine is a mechanically fixed movement. For example, a conventional automobile engine includes a crankshaft and several connecting rod assemblies that determine the mechanical movement of each piston within its respective cylinder. This pattern of engine piston motion is desirable because the position of the piston at any given point in the engine cycle is known with certainty, which simplifies the timing and motion of the engine. Although the efficiency of this conventional type of engine has been greatly improved in recent years, the inherent characteristics of this conventional engine still limit its efficiency. The power density of the engine is also limited, especially since the mechanically fixed movement of the pistons fixe...
