Straight-shaft engine

Abstract

The invention relates to a straight-shaft engine. The straight-shaft engine is characterized by comprising a main work cylinder, wherein the main work cylinder comprises a cavity; a main work piston, a connecting rod, a clutch internal tooth assembly and a transmission straight shaft passing through a gear are arranged in the cavity; a strip groove is formed on the middle part of the clutch internal tooth assembly; an internal tooth ring is arranged on the inside edge of the strip groove; the transmission straight shaft passes through the gear and the strip groove; a gear meshed with the single edge of the internal tooth ring is arranged on the transmission straight shaft; and a clutch mechanism for allowing the gear and the internal tooth ring to make unidirectional circulating rotation is arranged on the transmission straight shaft. The straight-shaft engine has the advantages that: 1, by the matching motion of the clutch internal tooth assembly and the gear, a straight shaft is driven to make unidirectional rotation, and the complex energy conversion mode of a crankshaft is changed, so the friction force is reduced and the effective power is improved; 2, an work assisting cylinder is arranged, so that the piston of the main work cylinder compresses exhaust gas upwards to push a piston of the work assisting cylinder to assist in applying work downwards, and the straight-shaft engine is favorable for energy conservation and emission reduction; and 3, the straight-shaft engine has a simple structure, reduces the cost of manufacturing the engine, and is favorable for popularization and application.

Description

【Technical field】

[0001] The present invention relates to an engine, and more particularly to a direct shaft engine. 【Background technique】

[0002] At present, the engines on the market are generally crankshaft engines. The crankshaft engine uses the working principle of four strokes. Three strokes assist one stroke to do work. In the third stroke, the piston moves downward in a straight line to do work, which is transferred to the crankshaft by the piston connecting arm and converted into rotational motion. At this time, when the piston is at the top dead center position and the crankshaft is at the top dead center, the maximum force of the combustion chamber at the moment of explosion has not been optimally utilized, which affects the effective performance of work. Moreover, the utilization of waste gas is a subject that people have been trying to solve but has not been able to solve well. If the waste gas can be used to assist work, it will be more conducive to energy sa...
