Embodiment 1

[0014] Embodiment 1: Embodiment 1 of the present invention—spline output variable compression ratio internal combustion engine. For the schematic diagram of the connection and structural relationship of the power output part, see figure 1 . Assuming that the internal combustion engine is a four-cylinder, the cylinder diameter is 79 millimeters, and the piston stroke is 100 millimeters. Double straight guide rails parallel to the reciprocating direction of the piston are set, and double guide wheels or double guide blocks are arranged on the crankshaft bearing support to cooperate with the double straight guide rails, so that the crankshaft and its bearings can and can only move along the double straight guide rails. The displacement of the crankshaft and its bearings is controlled by the screw drive, and the movable stroke of the crankshaft and its bearings is 70 millimeters.

Abstract

The invention relates to a piston reciprocating internal combustion engine. A crankshaft of the piston reciprocating internal combustion engine and a bearing of the crankshaft can move, a straight guide rail is utilized to set moving paths of the crankshaft and bearing, a screw drive mechanism is utilized to control the movement of the crankshaft and bearing of the crankshaft, thereby capable of continuously changing the compression ratio of the internal combustion engine. A matched spline output method for solving the problem of power output of the movement of the crankshaft is applied to adjust the design and manufacture of other subsidiary mechanisms of the internal combustion engine to adapt to the movement of the crankshaft and bearing of the crankshaft, thereby being capable of forming the complete and feasible internal combustion engine of the spline output of the variable compression ratio.

Description

technical field [0001] The invention relates to a piston reciprocating internal combustion engine, specifically a piston reciprocating internal combustion engine which changes its compression ratio by moving a crankshaft and outputs power through a specific bevel gear transmission and spline connection transmission. Background technique [0002] In order to improve the efficiency of the internal combustion engine, it is a technical improvement direction of the piston reciprocating internal combustion engine to adopt different compression ratios according to different working conditions. The existing variable compression ratio internal combustion engine realizes the variation of the compression ratio mainly by moving the cylinder head or by changing the length of the connecting rod. No one has proposed a complete and feasible method to change the compression ratio by controlling the moving crankshaft. If you want to change the compression ratio of the internal combustion engi...
