Embodiment 1

[0014] Embodiment 1: Embodiment 1 of the present invention—three-gear 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.

[0015] A crankshaft gear is arranged at one end of the crankshaft, a driven gear whose axis is...

Abstract

The invention relates to a piston reciprocating internal combustion engine. A crankshaft and a bearing thereof can move, a straight guide rail is used for setting the movement path of the crankshaft and the bearing thereof, a screw transmission mechanism is used for controlling the movement of the crankshaft and the bearing thereof, and then the compression ratio of the internal combustion enginecan be continuously changed. A matched three-gear-output method for solving the problem about power output of the moving crankshaft of the internal combustion engine is applied, the designing and manufacturing of other auxiliary mechanisms of the internal combustion engine are adjusted to adapt to the movement of the crankshaft and the bearing thereof, and the complete and feasible three-gear-output variable-compression-ratio internal combustion engine can be formed.

Description

technical field [0001] The invention relates to a piston reciprocating internal combustion engine, in particular to a piston reciprocating internal combustion engine which changes its compression ratio by moving a crankshaft and outputs power through specific intermeshing three-gear 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 engine by moving the cra...
